TestNG Based Selenium Tests not running in Parallel

Question

I am using the below TestNG Config to enable parallel execution of Selenium tests.

<?xml version="1.0" encoding="UTF-8"?>
<!DOCTYPE suite SYSTEM "http://testng.org/testng-1.0.dtd">

<suite name="Test-Automation" parallel="methods" thread-count="2" verbose="1">

    <test name="Suite Test">
        <classes>
            <class name="SampleTest">
                <methods>
                    <include name="firstTest"/>
                    <include name="secondTest"/>
                    <include name="thirdTest"/>
                </methods>
            </class>
        </classes>
    </test>
</suite>

Java Code:

@Test(dataProvider = "TestData")
public void firstTest(String data){
   //Code
}

@Test(dataProvider = "TestData")
public void secondTest(String data){
   //Code
}

@Test(dataProvider = "TestData")
public void thirdTest(String data){
   //Code
}

The Selenium tests are expected to run in parallel. I expect 2 browsers to be open and run the test script.

But I see only 1 browser and all 3 tests run one after the other and not in parallel. I have tried using test, methods, class, instance options for "parallel" attribute.

Any help?

What version of TestNG are you working with ?

This is due to a bug in TestNG 6.13.1 [ See GITHUB-1636 for more details ]

I have fixed this in the latest SNAPSHOT of TestNG (6.14-SNAPSHOT) and this should be available for use in the released version of TestNG (6.14).

But until then, please alter your suite xml file to look like below :

<?xml version="1.0" encoding="UTF-8"?>
<!DOCTYPE suite SYSTEM "http://testng.org/testng-1.0.dtd">

<suite name="Test-Automation" parallel="methods" thread-count="2" verbose="1">
    <test name="Suite Test" parallel="methods" thread-count="2" verbose="1">
        <classes>
            <class name="SampleTest">
                <methods>
                    <include name="firstTest"/>
                    <include name="secondTest"/>
                    <include name="thirdTest"/>
                </methods>
            </class>
        </classes>
    </test>
</suite>

The work-around is basically to add the attributes parallel="methods" thread-count="2" at the <test> level also.

I am seeing this problem again in 6.14.3 github.com/cbeust/testng/issues/1898

Krishnan Mahadevan Over a year ago

@sjethvani - Then you should file a new bug, and include all supporting information along with samples etc., which can be used to recreate the problem.

I have already commented this thing under relevant issue (github.com/cbeust/testng/issues/1898) . Should I file a new issue ?

Seperate all the test and then try with parallel="test"

    <test name="Suite Test1">
        <classes>
              <class name="//..//packg name..SampleTest">

            </class>
        </classes>
    </test>
  <test name="Suite Test2">
        <classes>
            <class name="//..//SampleTest">

            </class>
        </classes>
    </test>
  <test name="Suite Test3">
        <classes>
            <class name="//..//packg name..SampleTest">

            </class>
        </classes>
    </test>

</suite>

Is separating all methods from 1 class to multiple test, the only way? All test methods are from single class.

Krishnan Mahadevan Over a year ago

This is incorrect. Separating a class with 3 methods that are part of a single <test> tag into 3 <test> tags with each class and one method is the same. This doesn't solve the problem.

ACtually this duplication works and runs in 2 browsers parallel. But this will make duplicated lines in xml config.
