The Path to Rails 8 -Remediate Code Coverage Issue Introduced by the 7.1 Upgrade

We use the SimpleCov gem and our GitHub Action to report code coverage information to Coveralls, which provides code coverage metrics reporting for open source projects for free. In Rails 7.1, a feature was introduced where bin/rails test now runs test:prepare task. In most cases this provides a benefit, but when it comes to our test coverage measurement and reporting, this change poses a problem. We explore an issue in the SimpleCov GitHub repo that supports a similar issue with coverage reporting starting with Rails 7.1. We attempt to implement the solution offered, but it doesn't quite get things to the levels where they were before the upgrade. After reviewing the line-level coverage, it turns out that the lines newly marked as uncovered aren't actually being tested, so the coverage reporting is more accurate now. At the end, we inspect things, and the upgrade from 7.1 to 7.2 erased most of the inaccuracy anyway. We'll take it in stride and move on to the next video. This video covers: 0:00:00 Introduction and overview of the problem 0:02:10 Demonstrate the issue using the local version of SimpleCov's HTML output files 0:03:02 Review the SimpleCov GitHub issue about coverage dropping on the Rails 7.1 upgrade 0:03:47 Update the config/boot.rb file to require the SimpleCov code there instead of the beginning of the test_helper 0:04:14 Add parallelization code to test_helper 0:04:26 Re-run test suite and evaluate results: Coverage not up to previous level but appears more accurate 0:05:19 Attempt variant ways to invoke the tests: No effect on coverage reporting, but number of hits per line changes 0:06:25 Try moving the SimpleCov.start block into the config/boot.rb file. Negligible difference but left in. 0:07:56 Decide it's good enough and commit the changes, fixing a weird whitespace issue in the process. 0:09:09 Verify that the coverage registers properly in the GitHub action and Coveralls after pushing 0:10:59 Concluding remarks and looking forward to the upcoming videos #ruby #rails8 #simplecov #coveralls #rails #rubyonrails #rubygems #codecast #screencast #github #opensource #minitest #TDD #agile #NerdDice #DnD #roleplaying #softwaredevelopment #learntocode #tailwind #postgresql #rubocop #devise #turbo #controllers #views #selenium #capybara #systemtest See other related StatelessCode videos:    • Codecast: Create a RubyGem 28: Add Coveral...      • Add Coveralls to a Rails 7 Project      • The Path to Rails 8 - Upgrade Ruby from 3....      • The Path to Rails 8 - Upgrade Tailwind fro...      • The Path to Rails 8 - Update bundle and Up...      • The Path to Rails 8 - Upgrade Rails from 7...      • The Path to Rails 8 - Upgrade Rails from 7...   Resources that we relied upon for this solution: Coverage dropped in Rails 7.1 (fixed) issue on SimpleCov repo https://github.com/simplecov-ruby/sim...
