This article describes the TestNG Suite test, which is represented by a suite of XML files called Testng.xml in TestNG.

Each test method that uses testng is part of the suite.  A suite in testng is represented by an XML file that is typically named Testng.xml. The <suite> tag is the first label for this XML that represents a suite that can contain
<test> tags. Each <test> label corresponding may also contain one or more <classes>.
<packages>, <groups> tags.

When TestNG executes a suite, he mainly reads the XML content and executes it according to the XML definition.

Examples of Testng.xml

<?xml version= "1.0" encoding= "UTF-8"?> <!
DOCTYPE Suite SYSTEM "Http://testng.org/testng-1.0.dtd" >
<suite name= "tests" parallel= "tests" thread-count = "2" >
     
    <test name= "front-end" >
        <packages>
            <package name= " com.websystique.testng.frontend.* "/>
        </packages>
    </test>
 
    <test name=" Back-end " >
        <packages>
            <package name= "com.websystique.testng.backend.*"/>
        </packages>
    </test>
 
</suite>

<test> label has two value ' front-end ' & ' Back-end ' with name.

Each <test> label contains the specified package name. When TestNG wants to run this suite, it checks the packages to get the required running

Test classes and methods.

In this case the front-end and back-end tests can run in parallel.

Note: Each category of the suite, such as front-end, will run through a separate thread.

more Suite (suite) Examples
1 Perform all tests:

<?xml version= "1.0" encoding= "UTF-8"?> <!
DOCTYPE Suite SYSTEM "Http://testng.org/testng-1.0.dtd" >
<suite name= "tests" >
     
    <test name= "full" >
        <packages>
            <package name= "com.websystique.*"/>
        </packages>
    </test>
 
</suite>

2 perform all tests except the UI group

<?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>
        <packages>
            <package name= "com.websystique.*"/>
        </packages>
    </test>
 
</suite>

2 perform all tests except the UI group (with classes instead of packages)

<?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.TestCalculator"/>
        </classes>
    </test>
 
</suite>

Suite & Test Label level annotations: @BeforeSuite, @AfterSuiteTake @BeforeSuiteThe annotation method is executed once before any test method in the suite is executed.
This is a better fit to set up or initialize a shared environment for multiple groupings. @AfterSuite
The annotation method is executed once after any test method in the suite is executed.
This is a better fit to set up or initialize a shared environment for multiple groupings.
@BeforeTest, @AfterTest
@BeforeTest will be executed once before any method with <test> label is executed.
@AfterTest is the opposite. a complete example
