Exploring how to run specific tests using minitest

README.md

Hopefully this'll help me remember how to run individual tests using minitest.

Running all tests

$ ruby mini-test-name-matching.rb --verbose --seed 1
Run options: --verbose --seed 1

# Running:

TestNamesWithMiniTestAndShoulda#test_: NamesWithMiniAndShoulda should test_bar_1.  = 0.00 s = .

TestNamesWithMiniTest#test_foo_2 = 0.00 s = .

Finished in 0.002727s, 4400.7773 runs/s, 4400.7773 assertions/s.

12 runs, 12 assertions, 0 failures, 0 errors, 0 skips

Running single standard test

$ ruby mini-test-name-matching.rb --verbose --seed 1 \
--name "TestNamesWithMiniTest#test_bar_1"
Run options: --verbose --seed 1 --name TestNamesWithMiniTest#test_bar_1

# Running:

TestNamesWithMiniTest#test_bar_1 = 0.00 s = .

Finished in 0.001402s, 713.2530 runs/s, 713.2530 assertions/s.

1 runs, 1 assertions, 0 failures, 0 errors, 0 skips

Running single shoulda test

Note the additional space required at the end of the test name.

$ ruby mini-test-name-matching.rb --verbose --seed 1 \
--name "TestNamesWithMiniTestAndShoulda#test_: NamesWithMiniAndShoulda should test_bar_1. "
Run options: --verbose --seed 1 --name "TestNamesWithMiniTestAndShoulda#test_: NamesWithMiniAndShoulda should test_bar_1. "

# Running:

TestNamesWithMiniTestAndShoulda#test_: NamesWithMiniAndShoulda should test_bar_1.  = 0.00 s = .

Finished in 0.001786s, 559.9988 runs/s, 559.9988 assertions/s.

1 runs, 1 assertions, 0 failures, 0 errors, 0 skips

Running all tests matching 'foo_1'

$ ruby mini-test-name-matching.rb --verbose --seed 1 \
--name /foo_1/
Run options: --verbose --seed 1 --name /foo_1/

# Running:

TestNamesWithMiniTestAndShoulda#test_: NamesWithMiniAndShoulda should test_foo_1.  = 0.00 s = .
TestNamesWithMiniTestAndShoulda#test_: example-context should test_foo_1.  = 0.00 s = .

3 runs, 3 assertions, 0 failures, 0 errors, 0 skips

Running all tests matching 'should test_bar'

$ ruby mini-test-name-matching.rb --verbose --seed 1 \
--name "/should test_bar/"
Run options: --verbose --seed 1 --name "/should test_bar/"

# Running:

TestNamesWithMiniTestAndShoulda#test_: NamesWithMiniAndShoulda should test_bar_1.  = 0.00 s = .
