Getting SimpleCov-summary (0.0.5) to work with SimpleCov (0.16.1) and Rails 5.2

Standard

If you run into issues with installing simplecov-summary using:

# Put this in for RSpec, Minitest will plug in automatically
  RSpec.configure do |config|
    config.after(:suite) do
      if SimpleCov.running
        silence_stream(STDOUT) do
          SimpleCov::Formatter::HTMLFormatter.new.format(SimpleCov.result)
        end
 
        SimpleCov::Formatter::SummaryFormatter.new.format(SimpleCov.result)
      end
    end
  end
 

Here’s how to fix it:

# Put this in for RSpec, Minitest will plug in automatically
  RSpec.configure do |config|
    config.after(:suite) do
      SimpleCov.at_exit do
        SimpleCov::Formatter::SummaryFormatter.new.format(SimpleCov.result)
        SimpleCov::Formatter::HTMLFormatter.new.format(SimpleCov.result)
      end
    end
  end
 

Since Rails 5 removed silence_stream because it is not thread-safe. I found implementations of silence_stream but I got it to work by just removing it completely and I prefer to see these outputs at the end of my test run.
