An example of an AI chatbot conversation about configuring SimpleCov in Rails apps.
How do I configure SimpleCov in my Rails application?
To configure SimpleCov, first add it to your Gemfile: gem 'simplecov', require: false. Then, in your test helper file, require it and start it with SimpleCov.start.
Where exactly should I place the SimpleCov configuration code?
You should place the SimpleCov configuration code at the very top of your test_helper.rb or spec_helper.rb file, before any other requires.
Can I customize the coverage report output?
Yes, you can customize the output by using SimpleCov.coverage_dir to specify a different directory or by using SimpleCov.formatters to set different formatters.
What if I want to exclude certain files from the coverage report?
You can exclude files by using SimpleCov.start do block and specifying add_filter for the files or directories you want to exclude.
