Ruby Tests Profiling Toolbox
TestProf is a collection of different tools to analyze your test suite performance.
Why does test suite performance matter? First of all, testing is a part of a developer's feedback loop (see @searls talk) and, secondly, it is a part of a deployment cycle.
Simply speaking, slow tests waste your time making you less productive.
TestProf toolbox aims to help you identify bottlenecks in your test suite. It contains:
Plug'n'Play integrations for general Ruby profilers (
Factories usage analyzers and profilers
RSpec and minitest helpers to write faster tests
Who uses TestProf
- Discourse reduced ~27% of their test suite time
- Gitlab reduced 39% of their API tests time and improved factories usage
- Open Project
- ...and others
