#Quality Assurance

Code coverage isn't enough. Discover how mutation testing reveals whether your tests actually catch bugs by systematically introducing defects and measuring if your test suite detects them. Learn to use StrykerJS to improve test quality.

Discover how to build a compelling business case for QA investment. Learn to quantify the cost of bugs, measure QA ROI, demonstrate value to stakeholders, and position quality assurance as a strategic business driver�not just a cost center.

Move beyond example-based testing and discover a powerful paradigm that automatically generates hundreds of test cases to uncover hidden bugs and edge cases in your JavaScript code. Learn how to use fast-check to write properties that hold true for all inputs.

Flaky tests undermine confidence in your test suite and slow down development. Learn proven strategies to identify, debug, and eliminate test flakiness for reliable automation.
