Add cabbage mix tasks

[gmile]

I think it'd be great to have a cabbage mix task to tasks, tailored to features.

• mix cabbage run

  Particularly it'd be great to be able to run only features, optionally pointing to specific features:

  Like this:

  $ mix cabbage run                                              # runs all feature files
  $ mix cabbage run path/to/first.feature                        # runs only my_first.feature
  $ mix cabbage run path/to/first.feature path/to/second.feature # runs only my_first.feature and second.feature

• mix cabbage features

  Would display currently developed features.

  $ mix cabbage features
  Serve coffee
  Park a coffee
  Meet a bartender (wip)
  Make a dinner (wip)
  Register a user

So the current plan is to lean on ex unit to do that for you... Perhaps the readme could use some love but this is how it works today:

mix test path/to/feature.exs or mix test --only integration

I guess we could add tasks that basically did the same thing if that would be helpful since I know running the exs file isn't the most intuitive...

The #34 PR will give the ability to do the following:

Feature: Run just one test
  @any-made-up-tag-you-want
  Scenario: Targeting specific tests
    Given there is a test I wish to run
    When I execute "mix test --only any-made-up-tag-you-want"
    Then only this test is run

  Scenario: Another test
    Given this a test that should not run
    When I execute "mix test --only any-made-up-tag-you-want"
    Then this test does not run

Also, given that the exs version of that feature file is in test/tag_test.exs, you could run each specific test like: First scenario mix test test/tag_test.exs:3 Second scenario mix test test/tag_test.exs:8

Lastly it will allow a timeout value to be set in ExUnit by doing

Feature: Run just one test
  # Has double the standard test timeout of 60 seconds
  @timeout 120000
  Scenario: Targeting specific tests
    Given there is a test I wish to run
    When I execute "mix test --only any-made-up-tag-you-want"
    Then only this test is run

Is it possible to get mix test running all the tests, including the cabbage tests?

[revati]

Yes, currently works like that.

mix test <- runs all tests.

If you want to run only cabbage tests, set global tag for all cabbage tests via config.

 config :cabbage,
   # Default is []
   global_tags: :cabbage

`mix test --only=cabbage` <- will only run cabbage tests
