TestNG - Basic Annotations - AfterGroups
@AfterGroups annotated method will run only once after the execution of all the test methods of a specified group.
The following is a list of attributes supported by the @AfterGroups annotation:
Attribute | Description |
---|---|
alwaysRun |
For before methods (AfterClass, beforeTest, beforeTestClass and beforeTestMethod, but not beforeGroups): If set to true, this configuration method will be run regardless of what groups it belongs to. For after methods (afterSuite, afterClass, ...): If set to true, this configuration method will be run even if one or more methods invoked previously failed or was skipped. |
dependsOnGroups |
The list of groups this method depends on. |
dependsOnMethods |
The list of methods this method depends on. |
enabled |
Whether methods on this class/method are enabled. |
groups |
The list of groups this class/method belongs to. |
inheritGroups |
If true, this method will belong to groups specified in the @Test annotation at the class level. |
onlyForGroups |
Only for @BeforeMethod and @AfterMethod. If specified, then this setup/teardown method will only be invoked if the corresponding test method belongs to one of the listed groups. |
Create a Class
Create a java class to be tested, say, MessageUtil.java in /work/testng/src.
/* * This class prints the given message on console. */ public class MessageUtil { private String message; //Constructor //@param message to be printed public MessageUtil(String message) { this.message = message; } // prints the message public String printMessage() { System.out.println(message); return message; } }
Create Test Case Class
Create a java test class, say, TestAnnotationAfterGroups.java in /work/testng/src.
Add a test method testMethod() to your test class.
Add an Annotation @Test to method testMethod() and add this method to a group testOne.
Add a method afterGroups to the test class with annotation @AfterGroups and execute it after the testOne group by adding this annotation @AfterGroups("testOne")
Implement the test condition and check the behaviour of @AfterGroups annotation.
Following are the TestAnnotationAfterGroups.java contents:
import org.testng.Assert; import org.testng.annotations.Test; import org.testng.annotations.AfterGroups; public class TestAnnotationAfterGroups { MessageUtil messageUtil = new MessageUtil("Test method"); @AfterGroups("testOne") public void afterGroups(){ System.out.println("afterGroups method executed after testOne group"); } @Test(groups={"testOne"}) public void testMethod(){ Assert.assertEquals("Test method", messageUtil.printMessage()); } }
Create testng.xml
Next, let's create testng.xml file in /work/testng/src, to execute test case(s). This file captures your entire testing in XML. This file makes it easy to describe all your test suites and their parameters in one file, which you can check in your code repository or e-mail to coworkers. It also makes it easy to extract subsets of your tests or split several runtime configurations (e.g., testngdatabase.xml would run only tests that exercise your database).
<?xml version="1.0" encoding="UTF-8"?> <!DOCTYPE suite SYSTEM "https://testng.org/testng-1.0.dtd"> <suite name="Suite"> <test thread-count="5" name="Test"> <classes> <class name="TestAnnotationAfterGroups"/> </classes> </test> <!-- Test --> </suite> <!-- Suite -->
Compile the test case using javac.
/work/testng/src$ javac TestAnnotationAfterGroups.java MessageUtil.java
Now, run the testng.xml, which will run the test case defined in <test> tag. As you can see the @AfterGroups is called after all other test cases.
/work/testng/src$ java org.testng.TestNG testng.xml
Verify the output.
