Creating a data-driven test using JUnit

JUnit is a popular testing framework used to create Selenium WebDriver tests in Java. We can create data-driven Selenium WebDriver tests using the JUnit 4 parameterization feature. This can be done by using the JUnit parameterized class runner.

In this recipe, we will create a simple JUnit test case to test our BMI calculator application. We will specify the test data within our JUnit test case class. We will use various JUnit annotations to create a data-driven test.

Getting ready

The following are the things we need to do:

• Set up a new project and add JUnit4 to the project's build path. You can set up the project in an IDE of your choice.

• Identify the set of values that need to be tested.

How to do it...

Let's create a data-driven test using JUnit by following these steps:

1. Create a new JUnit test class that uses a parameterized runner using @RunWith(Parameterized.class):

   package com.secookbook.examples.chapter07;
   
   import org.openqa.selenium.firefox.FirefoxDriver...
