super_diff removes most rspec color output when run with parallel_tests

[fwolfst]

We use parallel_tests with rspec and rails. Once super_diff/rspec is required, most colors are stripped from the output. :(

When uncommenting Core::Formatters::ConsoleCodes (in monkey_patches.rb), the color comes back (but is gone in the colorful diff).

Seems to be in the console_code_for + wrap part, the only location I found (and I am wildly guessing here, do not understand the colorization), is in parallel_tests FailureLogger: https://github.com/search?q=repo%3Agrosser%2Fparallel_tests%20consolecodes&type=code .

🤦 Seems that enabling the colors via

# rails_helper.rb
SuperDiff.configure do |config|
  config.color_enabled = true
end

solves the issue. Still strange that without parallel rspec this setting was not necessary. My problem is gone however, so can be closed if no bells ring.

I suspect the following returns false as the spec suite itself does not run in a TTY session, when invoked by parallel_tests

    # lib/super_diff/configuration.rb#145
    def color_enabled_by_default?
      ENV["CI"] == "true" || $stdout.respond_to?(:tty?) && $stdout.tty?
    end
