simplecov-single_file_reporter

Install

gem install simplecov-single_file_reporter

Usage

Simple setup

Print coverage percent when you run a single file

require "simplecov/single_file_reporter"
SimpleCov.start
SimpleCov::SingleFileReporter.print

ruby test/a_test.rb
1 tests, 1 assertions
lib/a.rb coverage: 80.0

Customizing file-finding rules

SingleFileReporter needs to find the file that is tested.

test/test_xxx.rb -> lib/xxx.rb or app/xxx.rb

If it's something common, make a pull request.
If your app has special rules you can add them:

class MyReporter < SimpleCov::SingleFileReporter
  remove :file_under_test
  def self.file_under_test(test_file)
    super(test_file) || test_file.split("test/").last.sub("foo", "bar").sub("_test.rb", ".rb")
  end
end

SimpleCov.start
MyReporter.print
