TestNG Depedency Test – Multiple Test Method Dependency

Dependency is a feature in TestNG that allows a test method to depend on a single or a group of test methods. This will help in executing a set of tests to be executed before a test method.

The dependency on multiple test methods is configured for a test by providing comma separated dependent test method names to the attribute dependsOnMethods while using the Test annotation.

The following example shows a test class where process() test method depends on multiple test methods start() and initi() of the same class.

Code

package com.skilledmonster.example;
import org.testng.annotations.Test;
/**
* Example to demonstrate TestNG multiple dependency method execution
*
* @author Jagadeesh Motamarri
* @version 1.0
*/
public class MultipleDependencyTest {
@Test
public void start() {
System.out.println("Starting the server");
}
@Test(dependsOnMethods = { "start" })
public void init() {
System.out.println("Initializing the data for processing!");
}
@Test(dependsOnMethods = { "start", "init" })
public void process() {
System.out.println("Processing the data!");
}
@Test(dependsOnMethods = { "process" })
public void stop() {
System.out.println("Stopping the server");
}
}

Output


TestNG Depedency Test - Multiple Test Method Dependency - Output

As seen in the above console output, process() method executed after start() and init() methods are executed and like wise stop() method is executed after process()  method is executed.
