TestNG Dependencies | TestNG Tutorial

TestNG Dependencies:

Sometimes, you may need to invoke methods in a test case in a certain order. Here comes TestNG Dependencies into the picture.

TestNG allows you to specify dependencies either with annotations or in XML.

First, we see Dependencies with annotations:

TestNG allows you to specify dependencies either with:

• Using attribute dependsOnMethods in @Test annotations, OR.
• Using attribute dependsOnGroups in @Test annotations.

Check below video to see “TestNG Dependencies with Annotations”

package softwareTestingMaterial;

import org.testng.annotations.Test;

public class DependsOnMethodsTestCase {
	
	@Test
	public void testCase1(){
		System.out.println("Test Case 1");
	}
	@Test
	public void testCase2(){
		System.out.println("Test Case 2");
	}

}

testng.xml

<?xml version="1.0" encoding="UTF-8"?>
<!DOCTYPE suite SYSTEM "http://testng.org/testng-1.0.dtd" >

<suite name="softwaretestingmaterial">
	<test name="testngTest">
	
		<classes>
			<class name="softwareTestingMaterial.DependsOnMethodsTestCase" />
		</classes>
		
	</test>
</suite>

Console Output:

[TestNG] Running:

Test Case 1
Test Case 2

===============================================
softwaretestingmaterial
Total tests run: 2, Failures: 0, Skips: 0
===============================================

Now we add the dependsOnMethods attribute to the @Test Annotations and execute the same program.

See the script below.

package softwareTestingMaterial;

import org.testng.annotations.Test;

public class DependsOnMethodsTestCase {
	
	@Test(dependsOnMethods = {"testCase2"})
	public void testCase1(){
		System.out.println("Test Case 1");
	}
	@Test
	public void testCase2(){
		System.out.println("Test Case 2");
	}

}

Execute the same testng.xml which was placed above and see the difference in Console Output

Console Output:

[TestNG] Running:

Test Case 2
Test Case 1

Let’s see Dependencies with XML:

package softwareTestingMaterial;

import org.testng.annotations.Test;

public class DependsOnMethodsTestCase {
	
	@Test(groups = {"FirstGroup"})
	public void testCase1(){
		System.out.println("Test Case 1");
	}
	@Test(groups = {"SecondGroup"})
	public void testCase2(){
		System.out.println("Test Case 2");
	}

}
