Chapter 5: Analyzing Results & Reporting

Running a test is only half the job. The real value comes from analyzing the results and communicating findings to developers and stakeholders. In this chapter, you will learn how to:

  • Run tests from the command line (CLI mode) for accurate results.
  • Work with .jtl result files.
  • Generate the built-in HTML Dashboard Report.
  • Interpret key metrics and share reports with your team.

Reminder: Always run load tests in CLI (non-GUI) mode. The GUI extra consumes resources and can ruin your test or produce false-negative results because JMeter won’t be able to send requests fast enough.

Let’s start with JTL results files analysis using Listeners.
