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.

Must-have gems for mature Rails
gem "test-prof" - https://github.com/test-prof/test-prof | Toolkit for inspecting and optimising your test-suite, a must-have.
-
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. Docs: https://api.rubyonrails.org/classes/ActiveSupport/Notifications.html

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.

- Faker – generate fake data such as names, addresses, and phone numbers

Test Driving a Rails API - Part Two
While we’re at it, let's add a couple of other gems we’ll need for our test environment: factory_bot_rails is a fixtures replacement and generates test model instances. faker is handy for generating fake strings of data to be used in tests. Add those gems to the development and test group of your Gemfile:

Full-Text Search for Ruby on Rails with Litesearch
Next up, we'll combine a few of the techniques we've reviewed to implement snappy typeahead searching. Before we do that, though, let's generate more sample data. I will use the popular faker gem to do that:

Leveling up your custom fake data with Faker.js
Faker was originally written in Perl and is also available as a library for Ruby, Java, and Python.

Users of the Ruby programming language now have FFXIV mock data
Ah, so the data is just a giant .yml file of potential options, that I compiled, and then faker grabs a random one based on that data. There's no "database" or anything akin to that.
-
A proposal on how to deal with Monkey Patching
It's with the Faker library. I was able to reproduce it by spinning up a new rails up, specifying the faker gem , yours, and running the command gives the same error.
-
Faker Gem
To begin using faker, you need to install the gem, which is simply done by running "gem install faker". After you do that, you should add "gem "faker"" to your gem file to ensure correct usage, otherwise you may get an error. Once thats done you can head over to the seeding file and add require "faker" the page. In the seeding file is where you would start to "fake" your data and we use the faker library to pick out random dummy data. In the seeding, your gonna start implementing the data which should look like this,
