How to test Decidim engines


You need to create a dummy application to run your tests. Run the following command in the decidim root’s folder:

bundle exec rake test_app

Running a specific test file or just a single spec

If you are writing new specs, you can run the tests contained in a single file by opening a console window in the corresponding module and calling rspecon the file. For example:

cd decidim-participatory_processes
bundle exec rspec spec/forms/participatory_process_form_spec.rb

You can also run a single test by appending its start line number to the command:

bundle exec rspec spec/forms/participatory_process_form_spec.rb:134

Running tests for a specific component

A Decidim engine can be tested running the rake task named after it. For example, to test the proposals engine, you can run:

bundle exec rake test_proposals

Running the whole test suite

You can also run the full thing including test application generation and tests for all components by running

bundle exec rake test_all

But beware, it takes a long time…​ :)
