Running tests inside Rails plugin invokes rails test runner instead of rake test runner:

Since there is a Rake file with Rake::TestTask in rails plugin, the runner executes with the command:

bundle exec rails test test/file_test.rb

I tried deleting gemfile.lock and Test runner invokes the right command:

bundle exec rake test TEST="test/test_file.rb"

Is there a way to manually select the default test runner per application?
