Tutorial, First Selenium Webdriver Script: JAVA Code Example Tutorial, Customize, PDF & Email TestNG Reports in Selenium WebDriver. Selenium with TESTNG and eclipse IDE- Automation Beginner's guide Selenium IDE/Web driver has becoming a very popular testing tool as it is an open . The below given code is an example of how java classes and functions can be.

And it has been hard to recruit good testers with Selenium experience. I speak to so many people who get stuck at the IDE and don't progress further. I speak to so many testers who could get benefits from using automation but don't think they can understand the 'technical' aspects.

And there was nowhere I could direct those testers so they could learn. I wrote this book so that those testers can read through this tutorial, work through it at their own pace, and learn to automate web tests. I honestly wrote this because I want to see more testers with the technical skills to incorporate automation into their test processes.

And I know that it can seem daunting before you start. But automation is actually pretty simple.

Selenium Webdriver Tutorials

And I hope that by working through this tutorial, anyone can pick up the basics and start doing automated web testing. About the Author: Alan Richardson I've been doing testing my entire professional career - knocking on 18 years now. And over that time I've done a lot of automation, in a lot of different tools.

I've also done a lot of programming in a lot of different languages. At work, we use Selenium for our automation. It Is reference variable of object vehicle. Based on this example, Now we can say that object has three parts as bellow. Variable declaration for object. In this example, bicycle is the reference variable for object. This way you can use object of class and also you can create multiple objects of any class.

Bellow given example will show you how to create multiple object of class to pass different kind of multiple values In constructor. Both have different reference variables. As you know, Variable provide us a memory space based on type and size of declared variable to store a value.

There are different three types of variables available In java as bellow. Local Variables. Variables which are declared Inside methods or constructor are called as local variables for that method or constructor. Variables declared Inside method or constructor are limited for that method or constructor only.

You can not access to It outside that method or constructor. You can not use access modifiers with local variables because they are limited to that method or constructor block only. Need to initialize the value of local variables before using It because there Is not any default value assigned to local variables. Instance variables are declared on class level which is parallel to methods or constructors outside the method or constructor block.

Instance variables are generally used with objects. So they are created and destroyed with object creation and destruction. Instance non static variables are accessible directly by all the non static methods and constructors of that class.

If you wants to access Instance non static variables Inside static method, You needs to create object of that class. Instance variables are always Initialized with Its default values based on Its data types.

You can access Instance variable directly by Its name Inside same class. If you wants to access It outside the class then you have to provide object reference with variable name. Same as Instance variables, Class variables are declared on class level outside the method or constructor block. Only difference Is class variables are declared using static keyword. Class variables are used In rare case like when It Is predefined that value of variable will never change.

In that case we can use class variables. Class variables are visible to all methods and constructors of class. Class variables are visible to other class based on Its access modifiers.

Generally they are public. We can access class variables directly using Its name Inside same class. If you wants to access It outside the class then you need to use class name with variable. Bellow given example will give you some Idea about all three types of variables. Created two class to show you how to access class variable inside other class. Both these class will show you the access levels of all three types of variables. Console output will looks like bellow.

If interviewer asks you a definition of constructor then you can give him answer like: Constructor Is a code block which Is Called and executed at the time of object creation and constructs the values i. Each class have default no argument constructor In Java If you have not specified any explicit constructor for that class.

In java, Constructor looks like methods but bellow given properties of constructor are differentiate them from the methods. Constructor Creation Rules. Name of the constructor must be same as class name. Means If your class name Is Student then constructor name must be Student. Same as methods, We can pass parameters to constructors. Let me show you simple example of parameterized cunstructor In java.

Constructor will pass the values of objects one by to print them. Constructor Overloading As we know, Constructors name must be same as class name, When you create more than one constructors with same name but different parameters In same class Is called constructor overloading.

So question Is why constructor overloading Is required? Constructor overloading Is useful when you wants to construct your object In different way or we can say using different number of parameters. You will understand It better when we will look at simple example but before that let me tell some basic rules of constructor overloading.

If you are calling constructor from overloaded using this keyword, It must be first statement. It is best practice to call constructor from overloaded constructor to make It easy to maintain. Bellow given example shows best example of constructor overloading. First Name Is Jim 2. First Name Is Mary 2. Middle Name Is Elizabeth We can do same thing using single object creation too using this keyword as bellow. Used this keyword In overloaded constructor to call another constructor.

All these java object oriented concept tutorials are very. That's why I recommend you all to learn them very carefully. All these tutorials will also helps you to pass selenium webdriver Interview.

Now let me take you one step ahead to Inheritance In java. What Is Inheritance In Java? Inheritance parent-child Is very useful concept of java object oriented programming language by which we can reuse the code of parent class. Inheritance Is providing us a mechanism by which we can inherit the properties of parent class In to child class.

Using Inheritance, we can reuse the code of parent class In to child class so that size of code will decrease. Maintenance of code will be also very easy. Let me show you very simple example of Inheritance In java. In this example, Car class Is parent class of Audi class so all the non private properties of Car class are Inherited and able to use In Audi class.

This Is just basic example of Inheritance In Java. Overriding In sub class, When you create a method with same signature, return types and arguments of parent class's method then that sub class's method Is known as overridden method and It Is called as overriding In java. Overriding Is useful to change to the behavior of parent class methods. Let me show you simple example of method overriding In java.

Consider same above given example. Generally all cars have 4 seats so we have created Seats method with 4 seat variable. But supposing ford car has 6 seats and I wants to print 6 seats for Ford car.

In this case we can use method overriding In Ford class as bellow. For this example, Consider Car class of above example as parent class of Ford class. Here method Seats Is overridden In sub class. Another main thing to notice here Is we have created object of child class but reference Is given of parent class. If you will go for selenium webdriver Interview then Interviewer will ask you first question: What Is WebDriver?

So It Is most Important thing for all selenium webdriver learner to understand an Interface properly. Using Interface, We can create a contract or we can say set of rules for behavior of application. Interface Is looks like class but It Is not class. When you implements that Interface In any class then all those Interface rules must be applied on that class. In sort, If you Implement an Interface on class then you must have to override all the methods of Interface In your class.

This way, If you look at the code of Interface, You can get Idea about your program business logic. When you are designing big architecture applications like selenium webdriver, You can use Interface to define business logic at Initial level. Interface can be Implemented with any class using implements keyword. There are set of rules to be followed for creating an Interface.

Let me tell you all these rules first and then give you an example of an Interface. Variables Inside Interface must be static and mandatory to initialize the variable. By default all the methods and variables of Interface are public so no need to provide access modifiers. It will open New java Interface popup.

Give any name to Interface Example: College and click on save button. It will add College. No need to implement Interface. StudentDetails ; compdept. StudentDetails ; mecdept. XYZ Collage student details. Computer Dept. Student Detail Part Computer Dept. Student Result Part Mechanical Dept. Student Detail Part Mechanical Dept. When you are Initializing any browser using selenium WebDriver, You are writing statements like bellow.

ArrayList In Java. WebDriver Tutorial: Then question Is what Is arraylist In java and why we need It? Interviewer can ask you this question then you can give him answer like: ArrayList helps us to overcome this limitation of array because It can re-size automatically by Itself.

So finally we can say that when you don't know how many values you have to store In array, You can use ArrayList at place of simple array. We have to use arraylist many times In our selenium webdriver test case development. Store all links from page, store all buttons Id from page etc..

In all such case, You will not aware about how many values you have to store. Same thing we will use In selenium WebDriver test case development to store values. It will store only string values. Size constrain will comes never. You can do many more actions on arraylist object. One more thing we needs to use In selenium webdriver Is Hashtable.

What Is Hashtable? Hashtable Is a class In java and provides us a structure to store key and its value as a pair In table format. Means we can store value with Its key and can access that value using Its key. There Is not any Index of value In Hashtable. Key's Hashcode will be used to map the value with key In Heshtable. Let me show you very simple example of Hashtable.

Then I have used keys to access and print Its values. This way we can store and access values from hash table whenever required. Many times you will need reading or writing text file In your selenium webdriver test case development. For Example, You are reading some large data from web page and wants to store It In text file to use It somewhere else In future. Same way, You have to read data from file for some purpose. It Is very easy to Create, Write and read text file In java. Bellow given example will first of all create temp.

Then It will read both lines one by one from text file using while loop and print In console. You can use bellow given example code for reading or writing text file In your selenium webdriver test case whenever needed.

BufferedReader; java.

BufferedWriter; java. File; java. FileReader; java. FileWriter; java. Tutorials For Selenium WebDriver Anyone don't like exceptions and at the same time, anyone can not hide himself from exceptions when running webdriver tests because What Is An Exception? Exception can arise due to the many reasons like, network connection or hardware failure, Invalid data entered by user, DB server down etc.. So all these things can happens any time when you run your selenium webdriver test case and we can not stop It.

So Instead of thinking about stopping exception Which Is not possible during run time, Think about handling exceptions. Java provides very good exception handling mechanism to recover from this kind of errors. Let us learn different ways of handling exception In java. There are two types of exceptions In java as bellow. Checked Exception: Checked exceptions are those exceptions which are checked during compile time and needs catch block to caught that exception during compilation.

If compiler will not find catch block then It will throw compilation error. Very simple example of checked exception Is using Thread. If you will not put this statement Inside try catch block then It will not allow you to compile your program. Unchecked Exceptions: Unchecked exception are those exception which are not checked during compile time.

Generally checked exceptions occurred due to the error In code during run time. Handling exceptions using try-catch block We need to place try catch block around that code which might generate exception. In bellow given example, System. If you see, that statement Is written Inside try block so If that statement throw an exception - catch block can caught and handle It. Always use try catch block to log your exception In selenium webdriver reports.

Handling exceptions using throws keyword Another way of handling exception Is using throws keyword with method as shown In bellow given example. Supposing you have a throwexc method which Is throwing some exception and this method Is called from some other method catchexc. Now you wants to handle exception of throwexc method In to catchexc method then you need to use throws keyword with throwexc method.

As we learnt, throws keyword Is useful to throw those exceptions to calling methods which are not handled Inside called methods. Throw keyword has a different work - throw keyword Is useful to throw an exception explicitly whenever required. This Is the difference between throw and throws In java.

Interviewer can ask this question. Let us look at practical example. Code written Inside finally block will be executed always regardless of exception Is occurred or not. Main intention of using finally with try catch block Is: If you wants to perform some action without considering exception occurred or not. Let us see simple example of finally. Run above example and observe result. So In both the cases finally block will be executed.

So all these things about exception and ways of handling them will helps you In your webdriver test exception handling. Introduction of Selenium WebDriver What is selenium webdriver What is selenium webdriver and how it help us in software testing process? Webdriver in selenium http: However selenium WebDriver's development is in process so still there are few limitations and known issues available in.

Selenium WebDriver is also known as Selenium 2 and used for web as well mobile applications testing. It is freeware software testing tool and mostly used as a regression testing tool for web and mobile applications.

Selenium 2 supports most of all browsers to run your test cases and many programming languages like C , Java, Python, Ruby,. Net, Perl, PHP, etc.. Selenium 2 WebDriver controls browser directly from operating system level so it is interacting very fast and with more realistic way with browsers. Major people in world using Selenium webdriver with java.

WebDriver is using native automation from each and every supported language for running automation scripts on browsers. WebDriver supports web as well mobile application testing so you can test mobile applications iPhone or Android. You can share if you know any limitations or advantages of Selenium WebDriver by posting comments bellow. Click here to read more about WebDriver. You can read my next post about selenium webdriver download install.

Actually there is nothing to install except JDK. Let me describe you step by step process of download, installation and configuration of web driver and other required components.

You can view my post about "What is selenium webdriver" if you wants to know difference between WebDriver and selenium RC software tool. I am suggesting you to take a tour of Basic selenium commands tutorials with examples before going ahead for webdriver.

It will improve your basic knowledge and helps you to create webdriver scripts very easily. So your next question will be "how can i download java" Click here to download Java and install it in your system as per given installation guide over there.

Step 2: It is totally free. You can run 'eclipse. Step 3: Download WebDriver Java client driver. Selenium webdriver supports many languages and each language has its own client driver. Here we are configuring selenium 2 with java so we need 'webdriver Java client driver'. Click here to go on WebDriver Java client driver download page for webdriver download file. On that page click on 'Download' link of java client driver as shown in bellow image.

Downloaded 'webDriver Java client driver' will be in zip format. Extract and save it in your system at path D: There will be 'libs' folder, 2 jar files and change log in unzipped folder as shown in bellow figure. We will use all these files for configuring webdriver in eclipse. Double click on 'eclipse. First time when you start eclipse, it will ask you to select your workspace where your work will be stored as shown in bellow image.

Create new folder in D: You can change it later on from 'Switch Workspace' under 'file' menu of eclipse. Click on finish button. Now your new created project 'testproject' will display in eclipse project explorer as bellow. It will add new package with name 'mytestpack' under project name 'testproject'. It will add new class 'mytestclass' under package 'mytestpack'. That's all about configuration of WebDriver with eclipse.

Now you are ready to write your test in eclipse and run it in WebDriver. Run First Webdriver Script You need to install webdriver with eclipse to run your script in webdriver.

After installation of webdriver, You need to write a java code in eclipse for your test case of software web application. Let me give you one simple example of creating simple webdriver script. First of all you need to write code as bellow in your 'mytestclass. You can request if you wish this sample code file by submitting comment bellow with your email id.

Then driver. You can do same thing using "storeLocation" command in selenium IDE. So this is the simple webdriver script example. You can create it for your own software web application too by replacing URL in above script.

We will learn more scripts in detail in my upcoming posts. As you know, webdriver support Google Chrome browser too. You need to do something extra for launching webdriver test in in Google chrome browser.

Let me describe you steps to launch webdriver test in Google Chrome. Download ChromeDriver server First of all, download latest version of ChromeDriver server for webdriver.

You can download it directly from http: Click on link shown above to download chrome driver zip file. On completion of download, extract zip file to D: Don't forget to select 'public static void main String[] args ' method during new java class creation. Write code as shown bellow in class file. You can request this copy of this code by submitting comment bellow this post.

Look in to above image.

I set path for Google chrome driver as System. Downloading and installation Of JUnit with Eclipse How to download and install junit with eclipse step by step. We have already learn how to configure eclipse for webdriver, Creating new project, new package and then adding new class in my one of the previous post. In that post you can see how to add external jars of webdriver in eclipse. Also you can view how to run your first webdriver test in eclipse for better understanding.

Generally you do not need to install junit with eclipse if you have already added external jar files of webdriver with eclipse. Because required jar file for junit will be already there with webdriver jar files. In that window, go to Libraries tab. Here you will see all your jar files. In jar file tree view, look for the jar file name which is starting with junit. Java build path window.

If this kind of junit jar file is already there then you do not need to install junit jar with eclipse and you are ready to use junit with eclipse. But if junit jar file is not there then you need to add it. Downloading junit jar file Go to http: Here you will find the link like "junit. Click on it will redirect to junit jar file downloading page.

From this page download the latest version of junit jar file. Installing junit jar file with eclipse Go to java build path window as shown in above figure. After adding junit jar file, click on OK button to close java build path window. Now you are ready to use junit with eclipse for your webdriver test of software application. Click here to view all articles on webdriver. Please note that you need to add junit jar file only if it is not available in webdriver jar file folder. If it is already there with webdriver jar file folder then you not need to do anything to create and run junit test.

Now let me describe you how to create webdriver test case using junit. Webdriver test case creation using junit and eclipse You are already aware about how to create new project and package in eclipse and if you are not aware then please visit this post page. Look at bellow given image to know how to add JUnit Test Case. On Next page, Enter your test case name and click on Finish button.

When you add JUnit Test Case, your eclipse project explorer window will looks like bellow given image. Now replace bellow given code with your original code. Test; import org. WebDriver; import org.

It will show you Run As dialog as shown bellow. Eclipse will run your test case using JUnit and on completion of execution, you can see your result in JUnit pane as bellow.

Selenium Easy

Example - There are 2 junit test cases under your project's package. Now if you wants to run both of them then how will you do it? Simple and easy solution is creating JUnit test suite. If your project has more than 2 test cases then you can create test suite for all those test cases to run all test cases from one place. Before creating junit test suite, you must have to read my post about "How to download and install junit in eclipse" and "How to create and run junit test in eclipse".

Now let me describe you how to create junit test suite in eclipse for your junit test case. Add required external jar files for selenium webdriver. Test; org. By; org. WebDriver; org. After; org. Before; org. Ignore; org. Now we have 2 test cases junittest1. Now click on Next button. RunWith; import org. SuiteClasses; RunWith Suite.

RunWith annotation will references junit to run test in class and SuiteClasses describes classes included in that test suite. Now your junit test suite is created and project structure will looks like bellow. When you run junit test suite, eclipse will run both test cases junittest1 and junittest2 one by one. When execution completed, you will see bellow given output lines in console. This way we can create junit test suite to run multiple test cases from one place.

You must need to insert JUnit annotation inside the java code to execute your test case as junit test case. You can look in my previous post where i have used JUnit Test annotation before test method. Let me describe you mostly used 3 JUnit Annotations with example. You can view more details on JUnit at http: Before 2.

Test 3. After 2 other frequently used annotations are BeforeClass and AfterClass. Depending on annotation names, JUnit framework will decide the code execution flow. First JUnit framework will execute Before method, Second it will execute Test method and at last it will execute After method. Before Annotation As name suggest. Based on Before annotation, JUnit framework will execute that before method first. Generally method under Before annotation is used to initializing website and other environment related setup.

Before annotation method will be executed before each Test annotation method means if there are two Test methods in your class then Before method will be executed two times.

Method under After annotation is known as after method and execution of After method will start as soon as completion of Test method execution completion. Same as Before , After annotation method will be executed two times if there are two Test methods in your class. Test Method under Test annotation is known as test method. Execution of Test method will start as soon as Before method execution completed.

Generally we are writing all testing related activity under Test. We can use multiple Test methods in single class too.

BeforeClass Methods under BeforeClass annotation will be executed before the any test method starts execution. It will be executed only once even if there are multiple Test methods in your class. AfterClass AfterClass method will be run on completion of all the test method's execution from that class. Same as BeforeClass, AfterClass method will be executed once only. TimeUnit; import import import import import.

Now let me describe once more and then we will look at practical example for both of them. Difference between Before and BeforeClass annotations. Test method marked with Before annotation will be executed before the each Test method.

Means if there are 5 Test methods in your class then Before test method will be executed 5 times. Test method marked with BeforeClass annotation will be executed just before the class.

Means BeforeClass method will be executed only once before the class even if there are 5 Test methods in your class. Same as Before annotation, Test method marked with After annotation will be executed after the each Test method.

AfterClass annotation will be executed only once after last Test method executed. Execute bellow given Before and After annotations example in your eclipse and observe result in console. AfterClass; org. BeforeClass; org. WebDriver has a more concise syntax than Selenium 1. When you buy a new car, you get a manual that will tell you how to operate the radio and how to change the oil. But that manual wont tell you the best place to get your car serviced, or teach you how to drive. Like driving a car, there are things you must do for yourself.

Here are some things WebDriver does not do: WebDriver doesnt have the control of the timing of the elements appearing on the web page. Some might appear later and youll need to handle this yourself. WebDriver does not know when things have changed on the page, so you cant ask it to tell you when things have changed.

WebDriver doesnt provide many utilities for writing your code. You need to write these yourself. WebDriver doesnt provide built-in support for page elements that are composed of multiple elements, such as JavaScript calendars. WebDriver does not provide a framework to write your code in.

JUnit is a natural choice. WebDriver doesnt manage the browser. For example, you need to clean up after you have used it. WebDriver wont install or maintain your browsers. You need to do this yourself. Well cover all these important tasks in this book. It was written to simulate a human users action with Internet Explorer.

It just needed Java, which most developers had already installed on their machines. Selenium IDE is a graphic interface allowing users to record a browser navigation session, which can be replayed afterwards. Selenium WebDriver became the most popular choice among the Selenium tool suite, since it offers standardized operation to various Browsers through a common interface, WebDriver.

Today, when people talk about "Selenium," theyre usually talking about Selenium WebDriver. Why it is called Selenium? Jason Huggins joked about a competitor named Mercury in an email, saying that you can cure mercury poisoning by taking selenium supplements. Thats where the name Selenium came from. The tools you need to get started On top of a computer, access to the Internet, and a development environment, you will need some additional pieces of software to get started.

Why we use Java in this book While were aware that many developers wont be using Java as their main language. We chose it as the language for this book because we wanted to write for the most people possible, and Java is the most popular programming language. If youre using one of the many languages that WebDriver supports, such 13 Chapter 1: First steps as C , Ruby or Python, you should be able to replicate many of the techniques in this book.Selenium Locators and Examples using different locators.

One more thing you require to read data from table Is generating Xpath for each cell of column. Second else if block will be executed if value of variable k is greater than or equals to value of variable i and less than or equals to value of variable j. Where can you buy it? Clicking on any element or button of webpage. There are several difference between static and not static methods In java as described bellow. If compiler will not find catch block then It will throw compilation error.

Interviewer can ask this question.
