Reading and understanding reports

TestNG's Default Report

After a run, TestNG generates an HTML report in test-output, listing which tests passed, failed, or were skipped, along with execution time and error details for failures.

What to Look For

• Overall pass/fail counts, to get a quick health check of the build.
• Stack traces on failures, to identify the exact line and cause of failure.
• Patterns across failures — are several tests failing for the same underlying reason?

Extending Reporting

Many teams add a richer reporting library (like ExtentReports or Allure) on top of TestNG's basic report for more detailed, shareable results with screenshots.
