M.RB
m stands for metal, a better test/unit and minitest test runner that can run tests by line number.
INSTALL
Install via:
$ gem install m
If you’re using Bundler, you’ll need to include it in your Gemfile. Toss it into the test group:
group :test do
gem "m"
endUSAGE
Basically, I was sick of using the -n flag to grab one test to run. Instead, I prefer how RSpec’s test runner allows tests to be run by line number.
Given this file:
$ cat -n test/example_test.rb
1 require 'test/unit'
2
3 class ExampleTest < Test::Unit::TestCase
4 def test_apple
5 assert_equal 1, 1
6 end
7
8 def test_banana
9 assert_equal 1, 1
10 end
11 end
You can run a test by line number, using format m TEST_FILE:LINE_NUMBER_OF_TEST:
$ m test/example_test.rb:4
Run options: -n /test_apple/
# Running tests:
.
Finished tests in 0.000525s, 1904.7619 tests/s, 1904.7619 assertions/s.
1 tests, 1 assertions, 0 failures, 0 errors, 0 skips
Hit the wrong line number? No problem, m helps you out:
$ m test/example_test.rb:2
No tests found on line 2. Valid tests to run:
test_apple: m test/examples/test_unit_example_test.rb:4
test_banana: m test/examples/test_unit_example_test.rb:8
Want to run the whole test? Just leave off the line number.
$ m test/example_test.rb
Run options:
# Running tests:
..
Finished tests in 0.001293s, 1546.7904 tests/s, 3093.5808 assertions/s.
1 tests, 2 assertions, 0 failures, 0 errors, 0 skips
If you want to run all the tests in a directory as well as its subdirectories, use the -r flag:
$ m -r test/models
"Searching provided directory for tests recursively"
Run options:
..
Finished in 3.459902s, 45.0880 runs/s, 87.5747 assertions/s.
156 tests, 303 assertions, 0 failures, 0 errors, 13 skips
If you need to pass some option down to the actual runner, that is also supported:
$ m test/models -- --seed 1234
Run options: --seed 1234
..
Finished in 3.459902s, 45.0880 runs/s, 87.5747 assertions/s.
156 tests, 303 assertions, 0 failures, 0 errors, 13 skips
Ensure that you use the -- before the options, otherwise you'll get an invalid option error. Also, these extra option should always be the last argument.
SUPPORT
m works with a few Ruby test frameworks:
- Test::Unit
- ActiveSupport::TestCase
- MiniTest::Unit::TestCase
- Minitest
CONTRIBUTING
Testing
You can run all the tests with:
bundle exec rake tests
You can also run tests selectively. For minitest 4 run:
bundle exec rake test:minitest4
and the ones for minitest 5 with:
bundle exec rake test:minitest5
