Reporting Results and Analyze

Built-in TestNG Reports

After a run, TestNG automatically generates an HTML report (in the test-output folder) showing which tests passed, failed, or were skipped, along with execution time.

Analyzing Failures

• Reviewing the stack trace to understand exactly where and why a test failed.
• Checking whether a failure is a genuine defect or a flaky/environment issue.
• Cross-referencing failed tests against recent code changes.

Extending Reporting

Teams often integrate additional reporting tools (like ExtentReports or Allure) alongside TestNG for more detailed, shareable HTML reports with screenshots and logs.
