rails-minitest support

[nTraum]

Hi,

As it seems, rails-minitest and simplecov don't work nicely together yet, regardless of wether you use spec or unit test style (#235). When running the test suite via rake, the reported coverage seems to be wrong.

I'd like to help identify the problem and fix this.

---

Here's what I experienced and how my setup looks like (nTraum/tf2movies, I'm using spec style).

Test directory structure

Vanilla minitest-rails:

├── app
├── test
│   ├── controllers
│   │   └─── foos_controller_test.rb
│   ├── integration
│   ├── models
│   │   └─── foo_test.rb
│   └── test_helper.rb

With test_helper.rb requiring simplecov and starting SimpleCov with the rails profile at the very top.

Running the test suite

minitest-rails offers the following commands:

$ rake -D minitest
rake minitest
    Run default tests

rake minitest:all
    Run all tests

rake minitest:all:quick
    Run all tests, ungrouped for quicker execution

rake minitest:controllers
    Runs tests under test/controllers

rake minitest:integration
    Runs tests under test/integration

rake minitest:models
    Runs tests under test/models

Observations

rake minitest:all:quick, which runs all tests within one rake task works as expected, reported coverage is correct.

rake minitest:all, which seems to invoke separate rake tasks for each dir under test (correct me if I'm wrong) overrides previous coverage reports.

rake minitest:models, which only runs tests under test/models reports test coverage correctly for models. SimpleCov prints the following line though:

Coverage report generated for Integration Tests, Unit Tests to /home/ntraum/coding/tf2movies/coverage. 202 / 214 LOC (94.39%) covered.

Integration tests were not executed though.

rake minitest:controllers, s.a.

That's all I got.

Very similar problem with minitest-spec-rails You can reproduce the problem easily using https://github.com/ancorgs/mutant_tracker

What's in your Rakefile? See my comment #314 (comment)

Both repos use the default Rakefile. I'd recommend requiring SimpleCov at the very top, and either starting SimpleCov there, or using a .simplecov file
