Description
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 (ruby-prof, stackprof)
- Factories usage analyzers and profilers
- ActiveSupport-backed profilers
- RuboCop cops
- etc.
Of course, we have some solutions for common performance issues too, bundled into the gem.
