Running Specs

If you get '[Webpacker] Compilation Failed' when trying to run specs, you might need to get yarn to install its dependencies properly. One way of doing this is by precompiling the assets:

    yarn
    rake assets:precompile

This has the added benefit that it reduces the risk of timeouts when the tests are running, as assets will not get compiled on the fly.

Webpacker

You'll need to run webpack-dev-server when developing to ensure all the vue.js javascript is correctly compiled.

Writing specs

There are a few tools available to assist with writing specs:

Factory Bot

  • Strategies: You can use json :factory_name to generate the json that the API is expected to receive. This is very useful for mocking web responses. The association strategy is used for building nested json, it will usually only be used as part of other factories.

  • Traits:

    • api_object: Ensures that lots o the shared behaviour, like actions and uuids are generated automatically barcoded: Automatically ensures that barcode is populated with the correct hash, and calculates human and machine barcodes
    • build: Returns an actual object, as though already found via the api. Useful for unti tests
  • Helpers: with_has_many_associations and with_belongs_to_associations can be used in factories to set up the relevant json. They won't actually mock up the relevant requests, but ensure that things like actions are defined so that the api knows where to find them.

Request stubbing

Request stubs are provided by webmock. Two helper methods will assist with the majority of mocking requests to the api, stub_api_get and stub_api_post. See spec/support/api_url_helper.rb for details.

Note: Due to the way the api functions, the factories don't yet support nested associations.
