Performance testing using k6

Practical introduction to performance testing using k6 tool.

During this workshop you will go from analysis of tested app through writing your own performance tests in JavaScript to report creation and analysis.

At the end of this 24-hours long training you will be able to define stratego for your performance tests, write your own scripts in JavaScript, choose the right metrics, analyze reports and provide valuable information to business and management.
