How to use IntelliJ IDEA & Selenium Webdriver

Intellij is an IDE that helps you to write better and faster code. Intellij can be used in the option to Java bean and Eclipse.

In this tutorial, you will learn-

What is intelliJ

IntelliJ IDEA is a Java Integrated Development Environment (IDE). It is used for software development. It is developed by JetBrains. It comes under apache2 licenced ‘community edition‘ as well as ‘proprietary commercial edition‘. It is the finest available Java IDEs. It provides facilities like advanced code navigation and code refactoring capabilities.

The advantage of using intelliJ is that

  • It quickly generates getter and setter methods for object attributes.
  • With simple keystrokes, you can wrap a statement in a try-catch or if-else block.
  • The IDE delivers inbuilt packaging tools like gradle, SBT, grunt, bower, etc.
  • Database like SQL, ORACLE, PostgreSQL, Microsoft SQL Server can be accessed directly from the IDE.
  • It supports different languages like Java, javascript, Clojure, etc.
  • It is supported with different operating systems like Windows, Linux, etc. It can be downloaded from JetBrains official website.

Pre-requisites to IntelliJ with selenium webdriver

For that, we need to have some pre-requisites which are as follow.

  • IntelliJ
  • Any Web browser (preferably Mozilla Firefox)
  • JDK (Java Development Kit)
  • Selenium .jar files

The required jar files can be downloaded from Selenium.org official site. After download, the file extracts the .jar files into the desired directory.

How to Download & Install IntelliJ

Step 2) In the previous step when you Click -> Next. A new screen will open. In this screen, give project name. In our case, we have given name Selenium_Guru99. Then Click -> Finish. Your project has been created in IntelliJ.

Step 3) Now You need to add the Selenium‘s .jar files into intelliJ as external libraries.

For this Click go to File -> Project Structure -> in a project setting tab look for Modules ->Dependencies -> Click on ‘+‘ Sign -> Select for JARs or directories.

Step 4) Select all the selenium .jar files from the directory and subdirectory /lib, where you have extracted after download.

Now, you have successfully added the .jar files into intelliJ. If you see your project structure, then you will notice that you project‘s /src directory is empty.

Step 5) Right Click on /src directory -> New -> Java Class. Your project structure will look as shown below.

Example

We will use the site http://demo.guru99.com/.

In this test scenario

  • We will launch the URL
  • Enter Invalid Email ID
  • Click the ‘Submit‘ button
  • The output will be as shown below- ‘Email id is not valid‘

In above result, you can see that

  • When we run the code, Firefox instance is open.
  • At code level, we have provided an email to webelement. Which is an input field (abc.gmail.com).
  • When Selenium Webdriver clicks the ‘submit‘ button, email id is verified by guru99 site.
  • As we said that unregistered email would show message "Email ID is not valid."

Following is java code for test1.

import org.openqa.selenium.By;
import org.openqa.selenium.WebElement;
import org.openqa.selenium.firefox.FirefoxDriver;

public class TestSelenium {											
			public static void main(String[] args){        
				FirefoxDriver driver=new FirefoxDriver();        
				driver.get("http://demo.guru99.com/");        
				WebElement element=driver.findElement(By.xpath("//input[@name=‘emailid‘]"));        
				element.sendKeys("[email protected]");            

				WebElement button=driver.findElement(By.xpath("//input[@name=‘btnLogin‘]"));         
			button.click();    
		}
}

Summary
