MixTestObserver is a semiauto test runner. Run mix test when each time you write whose target path to the observing file.

For why:

• I want to run tests right away when I write codes.
• I sometimes think that run tests when I want it.

For your information:

• Maybe what you're looking for is mix-test.watch which is auto test runner.

This has been confirmed to work under the following conditions.

$ elixir -v
Erlang/OTP 24 [erts-12.2] [source] [64-bit] [smp:8:8] [ds:8:8:10] [async-threads:1] [jit]

Elixir 1.13.1 (compiled with Erlang/OTP 24)

def deps do
  [
    {:mix_test_observer, "~> 0.1.0", only: [:dev]},
  ]
end

Run the mix task:

mix test.observer <filepath>

Start observing <filepath>.

Next try writing test target path to <filepath> like $ echo 'test/' > <filepath>, then you can get the test results (mix test test/).

• If test target path is not matched test/ or */test/*, the observer run mix test --failure and mix test --stale.
• If you hope to get test results in file, run with --output <output_filepath> following your <filepath>, like mix test.observer <filepath> --output <output_filepath>.
• If you hope to configure mix test options, you can add it to the end of command, like mix test.observer <filepath> --include external:true.

For your information:

• Maybe you should prepare the shortcut function on your editor which write 'filepath:line' or 'filepath' to <filepath>.
