Previous post: TestNG Annotations Example

This article describes the use of @beforegroups, @AfterGroups annotations in testng group tests.

TestNG allows us to run multiple test methods in the form of a group.

We can group the test methods according to the behavior and so on.

Multiple tests can belong to a group, and a test can be part of multiple groups.

--------------------------------------

@BeforeGroups, @AfterGroups

The method with @beforegroups annotations will be executed once before any test methods in this group are executed.

Similar to this is the method with @aftergroups annotations that will be executed after any test method in this group

Package com.websystique.testng;
Import org.testng.annotations.AfterGroups;
Import org.testng.annotations.BeforeGroups;
 
Import Org.testng.annotations.Test; public class Testnggroupexample {@BeforeGroups ("security") public void setupsecurity () {System.out.pri
    Ntln ("setupsecurity ()"); 
    } @AfterGroups ("Security") public void teardownsecurity () {System.out.println ("teardownsecurity () \ n");
    } @BeforeGroups ("database") public void Setupdatabase () {System.out.println ("setupdatabase ()"); } @AfterGroups ("database") public void Teardowndatabase () {System.out.println ("teardowndatabase () \ n
    ");
    } @BeforeGroups (value= "UI") public void Setupui () {System.out.println ("setupui ()");
    } @AfterGroups (value= "UI") public void Teardownui () {System.out.println ("Teardownui () \ n"); } @Test (groups= "database") public void Testinsert () {System.out.println ("TeStinsert () ");
    } @Test (groups= "database") public void Testupdate () {System.out.println ("testupdate ()");
    } @Test (groups= "database") public void Testdelete () {System.out.println ("testdelete ()");
    } @Test (groups= "security") public void Accesshomepage () {System.out.println ("accesshomepage ()");
    } @Test (groups= "security") public void Accessadminpage () {System.out.println ("accessadminpage ()"); } @Test (groups= "UI") public void Openconfirmationdialog () {System.out.println ("openconfirmationdial
    OG () ");
    } @Test (groups= "UI") public void OpenFileDialog () {System.out.println ("OpenFileDialog ()"); }
}

MVN clean test or the TestNG Eclipse plugin mentioned in the first article runs this test:

Setupsecurity ()
accessadminpage ()
accesshomepage ()
teardownsecurity ()
 
setupui ()
Openconfirmationdialog ()
OpenFileDialog ()
Teardownui ()
 
setupdatabase ()
testdelete ()
Testinsert ()
testupdate ()
teardowndatabase ()
 
passed:accessadminpage
passed:accesshomepage
Passed:openconfirmationdialog
Passed:openfiledialog
passed:testdelete
passed:testinsert
passed:testupdate

@BeforeGroups is called once before any test methods in this group are executed.

@AfterGroups is called once after any test method in this group has been executed.

Group Expansion:

Let's say we only want to perform security and database-related tests, not UI-related.

We can use the TestNG configuration XML file to exclude the UI.

Create Testng.xml under the Src/test/resources folder

<?xml version= "1.0" encoding= "UTF-8"?> <!
DOCTYPE Suite SYSTEM "Http://testng.org/testng-1.0.dtd" >
<suite name= "tests" >
  
    <test name= " Backend ">
        <groups>
            <run>
                <exclude name=" UI "/>
            </run>
        </groups >
        <classes>
            <class name= "com.websystique.testng.TestNGGroupExample"/>
        </classes >
    </test>
  
</suite>

If you are practical with MAVEN-based projects, you can configure Maven-surefire-plugin in Pom.xml

Here is the configuration of the pomx.ml:

ersion>
                <configuration>
                    <suiteXmlFiles>
                        <suitexmlfile>src/test/resources/ testng.xml</suitexmlfile>
                    </suiteXmlFiles>
                </configuration>
            </plugin>
        </plugins>
    </build>
</project>

Right-click Testng.xml file-> runas->testng Suite]

Setupsecurity ()
accessadminpage ()
accesshomepage ()
teardownsecurity ()
 
setupdatabase ()
Testdelete ()
Testinsert ()
testupdate ()
teardowndatabase ()

You can see that the UI-related test methods and corresponding beforegroups/aftergroups are not running.
