ThreadPoolSize

The attribute will be invoked from multiple threads as specified by invocationCount.

Note: this attribute is ignored if invocationCount is not specified

Lets create java class
import org.testng.annotations.Test;
publicclassthreadpoolsizeexample {
@Test(invocationCount = 10,threadPoolSize=3 )
publicvoid testMethod1() {
System.out.println("This is testMethod1");
}
@Test
publicvoid testMethod2() {
System.out.println("This is testMethod2");
}
}
