After updating a project to rails 5 I was no longer able to use the minitest-ci gem without making a few changes. My project was failing with the following exception:
/home/ubuntu/ebth-com/vendor/bundle/ruby/2.2.0/gems/railties-5.0.1/lib/rails/test_unit/minitest_plugin.rb:57:in `plugin_rails_options': invalid option: --ci-dir=/tmp/circle-junit.pSCJhIM/minitest (OptionParser::InvalidOption)
To fix I basically had to override the test command so –ci-dir wouldn’t be specified. Here is the process as if you hadn’t even set up minitest-ci before:
1. Add minitest-ci to your Gemfile.
2. Run bundle
3. Add the following to your test_helper.rb:
|
1 2 3 4 5 6 7 |
require 'minitest' require 'minitest/autorun' require 'minitest/ci' if ENV['CIRCLE_TEST_REPORTS'] Minitest::Ci.report_dir = "#{ENV['CIRCLE_TEST_REPORTS']}/reports" end |
4. Edit your circle.yml and set up this test override:
|
1 2 3 4 5 |
override: - bundle exec rails test: parallel: true files: - test/**/*_test.rb |
