TestNG Default Report: Passed Tests Count

Given the following TestNG test class, what will be the count of passed tests shown in the default TestNG report after execution?

Selenium Java

import org.testng.annotations.Test;

public class SampleTest {
    @Test
    public void testA() {
        assert true;
    }

    @Test
    public void testB() {
        assert true;
    }

    @Test
    public void testC() {
        assert false;
    }
}

A 3

B 0

C 2

D 1

💡 Hint

Remember that tests with failed assertions are not counted as passed.

Tests testA and testB pass because their assertions are true. testC fails due to assertion false. So, the passed tests count is 2.

Assertion in TestNG Default Report for Skipped Tests

If a test method is annotated with @Test and depends on another test that fails, what will the default TestNG report show for the dependent test?

Selenium Java

import org.testng.annotations.Test;

public class DependencyTest {
    @Test
    public void test1() {
        assert false;
    }

    @Test(dependsOnMethods = {"test1"})
    public void test2() {
        assert true;
    }
}

A test2 is marked as passed in the report

B test2 is marked as skipped in the report

C test2 is marked as failed in the report

D test2 is not shown in the report

💡 Hint

Think about what happens when a dependency test fails in TestNG.

Since test1 fails, test2 which depends on test1 is skipped. The default TestNG report marks such tests as skipped.

Debugging Missing Test Results in TestNG Default Report

A tester notices that some test methods are not appearing in the TestNG default report after execution. Which of the following is the most likely cause?

A Test methods have assertions that always pass

B Test methods throw exceptions but are still marked as @Test

C Test methods are private instead of public

D Test methods are missing the @Test annotation

💡 Hint

TestNG only recognizes methods with a specific annotation as tests.

Only methods annotated with @Test are included in the report. Missing this annotation means TestNG ignores those methods.

Understanding TestNG Default Report Structure

Which section is NOT part of the default TestNG HTML report generated after test execution?

A Code coverage percentage for tested classes

B Detailed stack trace for failed tests

C Summary of passed, failed, and skipped tests

D Test execution time for each test method

💡 Hint

Think about what TestNG reports by default without extra tools.

TestNG default reports do not include code coverage data; that requires additional tools like JaCoCo.

Customizing TestNG Default Reports

Which of the following is the correct way to add custom logging information to the TestNG default report?

A Implement ITestListener and override onTestSuccess to add logs

B Modify the testng.xml file to include custom log tags

C Add System.out.println statements inside test methods

D Use @Listeners annotation to disable default reports and write logs

💡 Hint

TestNG allows listeners to hook into test events for custom behavior.

Implementing ITestListener and overriding methods like onTestSuccess allows adding custom logs to reports.
