Ruby Tests Profiling Toolbox VS strong_migrations

gem "test-prof" - https://github.com/test-prof/test-prof | Toolkit for inspecting and optimising your test-suite, a must-have.

You might be able to do something with https://test-prof.evilmartians.io, but I'm not sure it has anything specific to fixtures out of the box. Maybe using the event profiler on sql.active_record events would be close enough. In the limit, you could wire together your own ActiveSupport::Notifications.instrument around the relevant blocks + an ActiveSupport::Notifications.subscribe to that event so as to log the relevant information. Docs: https://api.rubyonrails.org/classes/ActiveSupport/Notifications.html

To have a better vision of what objects are created in our spec file we can use test-prof, a powerful gem that provides a collection of different tools to analyse your test suite performance. One of this tool is really useful to identify a factory cascade, let’s introduce factory profiler.

TestProf can be used to get flamegraphs for Ruby test suites.

Rspec has spec_helper.rb.

I also love the test-prof documentation, there's a lot of good ideas on how to improve test performance.

In the Rails world, the gem strong_migrations can be used to detect these: https://github.com/ankane/strong_migrations

The docs include a handy articulation of fixes.

gem "strong_migrations" - https://github.com/ankane/strong_migrations | Helps devs write non-blocking migrations, a must-have.

Frameworks will have a preferred solution. We use Rails with the strong_migrations gem which is great: https://github.com/ankane/strong_migrations

There’s no real way to test, but you can use gems like https://github.com/ankane/strong_migrations and not allow to merge branches unless they are up-to-date with main.

The strong migrations gem in Rails alerts when you're trying to make a migration that may be dangerous. Does anyone know an alternative for Javascript? Or maybe for raw SQL.

Half of the problems in this article are migration related.

I am extremely grateful that some people have created awesome libraries like strong migrations https://github.com/ankane/strong_migrations. Even if you are not using rails, bookmark its readme, it is an awesome cheat-sheet when writing a migration.

I would suggest taking a look at strong migrations[1]. It's a rails project, but the readme does a great job explaining what it checks for and what safe alternative to use instead. I still link to their explanations in PRs for non-rails projects.
