rubocop-junit_formatter

A JUnit Formatter for RuboCop. Usable with continuous integration services (eg. CircleCI) and IDEs.

You must require the formatter file through the RuboCop CLI.

$ rubocop --require rubocop/formatter/junit_formatter --format RuboCop::Formatter::JUnitFormatter

To output the results to a file, use the -o/--out option:

$ rubocop --require rubocop/formatter/junit_formatter \
          --format RuboCop::Formatter::JUnitFormatter \
          --out /tmp/test-results/rubocop.xml

You can even have use multiple formatters (see RuboCop manual). This is good for CIs where you want to stdout to be a more human readable formatter and output the JUnit XML to a file.

Add this line to your application's Gemfile:

gem 'rubocop-junit_formatter'

You'll probably only need to scope it to the test group.
