Ruby Tests Profiling Toolbox

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 (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.
