Stars - the number of stars that a project has on GitHub. Growth - month over month growth in stars.
Activity is a relative number indicating how actively a project is being developed. Recent commits have higher weight than older ones.
For example, an activity of 9.0 indicates that a project is amongst the top 10% of the most actively developed projects that we are tracking.

Evaluating More Coverage in Ruby 3.2
Have you wondered how much of the logic in your views is exercised in your test suite? Thanks to this change, now you can see that in tools like SimpleCov.

My First Code Commit in Ruby
My talk is about different best practices - specifically when adhering to them breaks down. One of those best practices is high test coverage. I start to work on the content for my presentation by building the code samples that I want to use in the slides. For the code coverage section, I'm writing some code with some tests. I'm using SimpleCov to generate code coverage results.

Improve Code in Your Ruby Application with RubyCritic
SimpleCov - a tool to check Ruby application code coverage. You can configure it to run alongside your tests. It provides metrics on code coverage so that you can identify what you need to pay attention to and where to invest your time to create better test cases.
-
Paying Down Technical Debt
Ensure that you have sufficient test coverage. You can use code coverage analysis tools like SimpleCov to gain insight into gaps in your coverage.

How to test all workers in one big loop?
simplecov might the answer you need, it generates a report of the lines of code your test suite hits.
-
How to Improve Code Quality on a Ruby on Rails Application
Use SimpleCov to generate a report of how many statements are covered by your test suite. It won't assess the test suite quality, though.

Ruby's Got You Covered
There are many tools for measuring test coverage, but one is SimpleCov. It also supports branches coverage. To measure coverage of production code, check out Coverband, which you can set up to use oneshot lines mode.

Must-have gems for mature Rails

Measuring load time on fixtures
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.

How to optimize factory creation.
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.

A Trick For Reading Flamegraphs
TestProf can be used to get flamegraphs for Ruby test suites.

Does pytest break a lot of coding rules?
Rspec has spec_helper.rb.

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