How to execute multiple classes at once using TestNG

Question

I have just started learning selenium and was wondering that if there is a possible way of executing multiple classes at once in TestNG?

Can someone help?

Hey @Sradha, Yes it is possible in TestNG.

All you need to do is create a XML file and list all the different class you want to test at once.

Here is the syntax:

<!DOCTYPE suite SYSTEM "http://testng.org/testng-1.0.dtd" >

<suite name = "TestNG">

    <test = "Testing TestNG">
    
        <classes>
        
            <class name = "testNG.class1"/>
            <class name = "testNG.class2"/>
            <class name = "testNG.class3"/>

            
        </classes>
        
    </test>

</suite>

This way you can run the test cases in each class at once.

Hi, 

I am facing the below issue, please help if you can

Running multiple classes but classes contain priority set 1, 2, 3

xml:

<!DOCTYPE suite SYSTEM "http://testng.org/testng-1.0.dtd" >
<suite name="REGRESSION_TEST_SET" parallel="tests" thread-count="3" preserve-order="true">
    <test name="MOBILE" >

        <classes>
            <class name="LoginTest"/>
            <!--<class name="StopSizeTest" />-->
        </classes>
    </test>
</suite>

Above is the xml , so what happening is - it executed class Login Test with priority 1 test case and then jump to Class StopsizeTest with priority 1 test case

All i want is to execute class login test first with all priority test 1, 2 and 3 then come to class stopsize test run all priority of that class

Please help

So basically you want to run the tests from a single class at the same time. Is that your query?
