In TestNG, we use dependOnMethods and dependsOnGroups to implement dependency testing. If a dependent method is fail, all the subsequent test methods will be skipped, NOT failed.
1. dependOnMethods Example
A simple example, “method2()” is dependent on “method1()”.
1.1 If method1() is passed, method2() will be executed.
App.java
package com.mkyong.testng.examples.dependency;
import org.testng.annotations.Test;
public class App {
@Test
public void method1() {
System.out.println("This is method 1");
}
@Test(dependsOnMethods = { "method1" })
public void method2() {
System.out.println("This is method 2");
}
}
Output
This is method 1
This is method 2
PASSED: method1
PASSED: method2
===============================================
Default test
Tests run: 2, Failures: 0, Skips: 0
===============================================
1.2 If method1() is failed, method2() will be skipped.
App.java
package com.mkyong.testng.examples.dependency;
import org.testng.annotations.Test;
public class App {
//This test will be failed.
@Test
public void method1() {
System.out.println("This is method 1");
throw new RuntimeException();
}
@Test(dependsOnMethods = { "method1" })
public void method2() {
System.out.println("This is method 2");
}
}
Output
This is method 1
FAILED: method1
java.lang.RuntimeException
at com.mkyong.testng.examples.dependency.App.method1(App.java:10)
//...
SKIPPED: method2
===============================================
Default test
Tests run: 2, Failures: 1, Skips: 1
===============================================
2. dependsOnGroups Example
Let create few test cases to demonstrate the mixed use of dependsOnMethods anddependsOnGroups. See comments for self-explanatory.
TestServer.java
package com.mkyong.testng.examples.dependency;
import org.testng.annotations.Test;
//all methods of this class are belong to "deploy" group.
@Test(groups="deploy")
public class TestServer {
@Test
public void deployServer() {
System.out.println("Deploying Server...");
}
//Run this if deployServer() is passed.
@Test(dependsOnMethods="deployServer")
public void deployBackUpServer() {
System.out.println("Deploying Backup Server...");
}
}
TestDatabase.java
package com.mkyong.testng.examples.dependency;
import org.testng.annotations.Test;
public class TestDatabase {
//belong to "db" group,
//Run if all methods from "deploy" group are passed.
@Test(groups="db", dependsOnGroups="deploy")
public void initDB() {
System.out.println("This is initDB()");
}
//belong to "db" group,
//Run if "initDB" method is passed.
@Test(dependsOnMethods = { "initDB" }, groups="db")
public void testConnection() {
System.out.println("This is testConnection()");
}
}
TestApp.java
package com.mkyong.testng.examples.dependency;
import org.testng.annotations.Test;
public class TestApp {
//Run if all methods from "deploy" and "db" groups are passed.
@Test(dependsOnGroups={"deploy","db"})
public void method1() {
System.out.println("This is method 1");
//throw new RuntimeException();
}
//Run if method1() is passed.
@Test(dependsOnMethods = { "method1" })
public void method2() {
System.out.println("This is method 2");
}
}
Create a XML file and test them together.
testng.xml
<!DOCTYPE suite SYSTEM "http://testng.org/testng-1.0.dtd" >
<suite name="TestDependency">
<test name="TestCase1">
<classes>
<class
name="com.mkyong.testng.examples.dependency.TestApp">
</class>
<class
name="com.mkyong.testng.examples.dependency.TestDatabase">
</class>
<class
name="com.mkyong.testng.examples.dependency.TestServer">
</class>
</classes>
</test>
</suite>
Output
Deploying Server...
Deploying Backup Server...
This is initDB()
This is testConnection()
This is method 1
This is method 2
