guard-minitest falsely claims there are 0 tests to run

$ ruby hamming_test.rb
# ...
15 runs, 0 assertions, 0 failures, 2 errors, 13 skips

BUT:

$ guard

$ guard -d

ruby -I"test" -I"spec" -r minitest/autorun -e ""

What if you run just that command instead of guard?

[jottr]

$ ruby -I"test" -I"spec" -r minitest/autorun -e ""
#...
0 runs, 0 assertions, 0 failures, 0 errors, 0 skips

When I edit it as follows, the tests are run:

$ ruby -I"-r minitest/autorun -e " hamming_test.rb
# ...
15 runs, 0 assertions, 0 failures, 2 errors, 13 skips

The files have to be within directories specified with the test_folders option.

Your file hamming_test.rb is neither in spec nor test, so it's ignored.

See: https://github.com/guard/guard-minitest#test_folders-and-test_file_patterns

I'd suggest just moving hamming_test.rb to a test subdirectory.

And change the watches to handle this.

Thx for the info. Instead of moving the files, I did:

guard :minitest, test_folders: './', test_file_patterns: '*_test.rb' do
which made more sense in my particular case.
