First Test Script

Creating out first test script and understanding it

Creating First Test Script

1. Create a package in src/test/java called com.practice (Can be anything).

2. Create a class FirstTest.java like below.

package com.practice;

import org.testng.Assert;
import org.testng.annotations.Test;

public class FirstTest {

	@Test
	public void helloworldTest() {
		String message = "Hello world!!";
		Assert.assertTrue(message.contains("Hello"));
	}
	
	@Test
	public void failingTestCase() {
		String message = "Hello world!!";
		Assert.assertTrue(message.contains("hello"));
	}
}

3. Run the test cases. <right-click-class> -> Run As-> TestNG Test This option should appear if you have installed TestNG plugin to eclipse.

4. Console output Once we run the test, we should see something like this in the console

Console Output

We are intentionally failing the second test.

Understanding the FirstTest

• Our FirstTest class has two methods both annotated with @Test annotation. So in TestNG all the methods that are annotated with @Test annotation are test methods or test cases.

• @Test can be applied on class level also. In that case it'll consider all the public methods in the class as test methods.

So we we run the test case using TestNG plugin, keep in mind that we are not the one who created instance of FirstTest.java and called helloworldTest() and failingTestCase() . TestNG did it. (This is why we use testing frameworks like JUnit, TestNG etc.,)

And what goes inside those test methods is entirely in our hand.

We can use both org.junit.Assert and org.testng.Assert
