Can not set different attributes to "iTestContext" while do parallel test class execution.

[Hasini weerasooriya]

I'm trying to run multiple test classes in parallel. For example, I'm running 2 test classes in parallel using xml file. In my test classes I used two different @BeforeClass annotations in which I try to set two different attributes for "iTestContext". But While I'm running the test classes the "iTestContext" value is always the same.

My expectation is to execute parallel test with @BeforeClass annotation setting different values ​​for "iTestContext" in different test classes.

Sample Script:

Test class 01:

@Listeners(CustomITestListener.class)
public class SampleTest01 {

   @BeforeClass(alwaysRun = true)
   public void init(ITestContext iTestContext) {
          iTestContext.setAttribute("feature", "Login");

   }

   @Test(description = "Sample Test 1")
   public void testSample1() {

   ...

   }

}

Test class 02:

@Listeners(CustomITestListener.class)
public class SampleTest02 {

   @BeforeClass(alwaysRun = true)
   public void init(ITestContext iTestContext) {
          iTestContext.setAttribute("feature", "Create Page");

   }

   @Test(description = "Sample Test 2")
   public void testSample2() {

   ...

   }

}

xml Script:

<!DOCTYPE suite SYSTEM "http://testng.org/testng-1.0.dtd">
<suite name="Thread Local Test Suite" parallel="classes" thread-count="20">
   <test name="Thread Local Tests" >
      <classes>
         <class name="ThreadLocalTests.SampleTest01"/>
         <class name="ThreadLocalTests.SampleTest02"/>
      </classes>
   </test>
</suite>

Requesting support on this issue.

This works fine on the latest released TestNG version (7.10.1).

Please try again using this version.

Thanks & Regards

Hi  Krishnan,

Thanks for your response. I tried with the latest released TestNG version 7.10.1 and it also had the same problem.

• If you are trying to work with a single <test> tag, then you will ONLY have 1 ITestContext object.
• Attributes within an ITestContext are stored as Key/Value Pairs.
• If you use the same key, you are going to overwrite the values.

The right way to do this would be to split your test classes into multiple <test> tags wherein each <test> tag contains exactly 1 test class and then you choose parallel as “tests” (This tells TestNG to run all my <test> tags in parallel). This gives you the same parallelism that you are going to get when you use parallel=“classes” but with just 1 <test> tag.

Here’s the sample that am working with.

import org.testng.ITestContext;
import org.testng.annotations.BeforeClass;
import org.testng.annotations.Test;

public class SampleTestClass {

    @BeforeClass(alwaysRun = true)
    public void init(ITestContext iTestContext) {

        System.err.println("Setting feature for " + iTestContext.getName());

        iTestContext.setAttribute("feature", "Login");
    }

    @Test(description = "Sample Test 1")
    public void testSample1() {
    }
}

import org.testng.ITestContext;
import org.testng.annotations.BeforeClass;
import org.testng.annotations.Test;

public class SampleTestClass2 {

    @BeforeClass(alwaysRun = true)
    public void init(ITestContext iTestContext) {

        System.err.println("Setting feature for " + iTestContext.getName());

        iTestContext.setAttribute("feature", "Create Page");
    }

    @Test(description = "Sample Test 2")
    public void testSample2() {
    }
}

import org.testng.IReporter;
import org.testng.ISuite;
import org.testng.ISuiteResult;
import org.testng.xml.XmlSuite;

import java.util.List;

public class Printer implements IReporter {

    @Override
    public void generateReport(List<XmlSuite> xmlSuites, List<ISuite> suites, String outputDirectory) {
        suites.stream()
                .flatMap(it -> it.getResults().values().stream())
                .map(ISuiteResult::getTestContext)
                .forEach(it -> {
                    System.err.println("Printing attributes for " + it.getName());
                    it.getAttributeNames()
                            .forEach(attribute -> System.err.println(attribute + ": " + it.getAttribute(attribute)));
                });
    }
}
