Testng: Dataprovider is executed for ignored tests in case of the BeforeClass failure

Quick question : why do you want the data provider to be executed when a @BeforeClass has a failure? Can you please elaborate

Hi!
The thing is that I don't want to execute dataproviders in such case, but they are executed ;)
So if it's a bug, I will be glad to hear that. But if it's a feature - alwaysRun would let someone still use it. For questionable reasons.

That's why I wrote:

Expected behavior
Dataprovider is skipped when the @BeforeClass configuration method fails, and all the tests are skipped.

Ah ok! Sorry I misread it. Let me see what is going on. I agree. It's a bit counter intuitive for the data provider to still run when there is a config failure at class level.

@baflQA - Fixing this issue is going to be tricky from TestNG side. It looks like fixing this would cause a lot of regression.

So here's an easy work-around that would ensure that the data provider doesn't get executed if there's a configuration failure.

import static org.testng.Assert.fail;

import com.rationaleemotions.github.issue2049.SampleTestClass.FailureDetecter;
import org.testng.IConfigurationListener;
import org.testng.ITestContext;
import org.testng.ITestResult;
import org.testng.annotations.BeforeClass;
import org.testng.annotations.DataProvider;
import org.testng.annotations.Listeners;
import org.testng.annotations.Test;

@Listeners(FailureDetecter.class)
public class SampleTestClass {
  @BeforeClass
  public void beforeClass() {
    System.err.println("BEFORE CLASS");
    fail();
  }

  @Test(dataProvider = "dp1master")
  public void test1(Class<?> clazz) {
    System.err.println("Running test for class " + clazz.getSimpleName());
  }

  @DataProvider
  public Object[][] dp1master(ITestContext ctx) {
    if (ctx.getAttribute(FailureDetecter.FAILURE) != null) {
      throw new RuntimeException("Failure");
    }
    return new Object[][] {new Object[] {Object.class}, {Object.class}};
  }

  public static class FailureDetecter implements IConfigurationListener {
    public static final String FAILURE = "failure";

    @Override
    public void onConfigurationFailure(ITestResult itr) {
      itr.getTestContext().setAttribute(FAILURE, Boolean.TRUE.toString());
    }
  }
}

Output

BEFORE CLASS

java.lang.AssertionError: null

Hi @krmahadevan ! Thx for Your effort.
I'm sad to hear that it's not a piece of cake to fix this ;)
Based on Your comment I've come up with this approach:
https://github.com/baflQA/testNG_parallel_debug/commit/321fbcc8872df5e611c788e13dc2e62add805163
Looks like it will do the same, but I won't need to implement the logic in each dataprovider I have.
So, I'm fine with this approach, and I think We can close this issue.

@baflQA - Awesome. Good improvisation there :)

Based on your comments, I am closing this issue.
