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.

Based on the "Testing" category.
Alternatively, view Ruby Tests Profiling Toolbox alternatives based on common mentions on social networks and blogs.
-
vcr
Record your test suite's HTTP interactions and replay them during future test runs for fast, deterministic, accurate tests. -
minitest
minitest provides a complete suite of testing facilities supporting TDD, BDD, mocking, and benchmarking. -
timecop
A gem providing "time travel", "time freezing", and "time acceleration" capabilities, making it simple to test time-dependent code. It provides a unified method to mock Time.now, Date.today, and DateTime.now in a single call. -
Spork
A DRb server for testing frameworks (RSpec / Cucumber currently) that forks before each run to ensure a clean testing state. -
Konacha
Test your Rails application's JavaScript with the mocha test framework and chai assertion library -
Fabrication
DISCONTINUED. This project has moved to GitLab! Please check there for the latest updates. -
Knapsack
Knapsack splits tests evenly across parallel CI nodes to run fast CI build and save you time. -
ActiveMocker
Generate mocks from ActiveRecord models for unit tests that run fast because they don’t need to load Rails or a database. -
Wrong
Wrong provides a general assert method that takes a predicate block. Assertion failure messages are rich in detail. -
RR
RR is a test double framework that features a rich selection of double techniques and a terse syntax. ⛺ -
turbo_tests
Run RSpec tests on multiple cores. Like parallel_tests but with incremental summarized output. Originally extracted from the Discourse and Rubygems source code. -
RSpecTracer
RSpec Tracer is a specs dependency analyzer, flaky tests detector, tests accelerator, and coverage reporter tool for RSpec. It maintains a list of files for each test, enabling itself to skip tests in the subsequent runs if none of the dependent files are changed. It uses Ruby's built-in coverage library to keep track of the coverage for each test.

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
RSpec and minitest helpers to write faster tests
RuboCop cops
etc.
Who uses TestProf
- Discourse reduced ~27% of their test suite time
- Gitlab reduced 39% of their API tests time and improved factories usage
- CodeTriage
- Dev.to
