How to Run a Single Test in Minitest

Is it possible to run a single test in MiniTest?

I'm looking for similar functionality to rspec path/to/file.rb -l 25

With Nick Quaranto's "m" gem, you can say:

m spec/my_spec.rb:25

How do I run a single test file in minitest?

bin/rails test test/controllers/issues_controller_test.rb

How to run MiniTest::Unit tests in ordered sequence?

You can use i_suck_and_my_tests_are_order_dependent!() class method.

class MyTest < MiniTest::Unit::TestCase
  i_suck_and_my_tests_are_order_dependent!   # <----

  def test_1
    p 1
  end

  def test_2
    p 2
  end
end

But as the name suggest, it's not a good idea to make the tests to be dependant on orders.

How to run a single test from a Rails test suite?

NOTE: This doesn't run the test via rake. So any code you have in Rakefile will NOT get executed.

To run a single test, use the following command from your rails project's main directory:

ruby -I test test/unit/my_model_test.rb -n test_name

This runs a single test named "name", defined in the MyModelTest class in the specified file. The test_name is formed by taking the test name, prepending it with the word "test", then separating the words with underscores. For example:

class MyModelTest < ActiveSupport::TestCase
  test 'valid with good attributes' do
    # do whatever you do
  end

  test 'invalid with bad attributes' do
    # do whatever you do
  end
end

You can run both tests via:

ruby -I test test/unit/my_model_test.rb

and just the second test via

ruby -I test test/unit/my_model_test.rb -n test_invalid_with_bad_attributes

How to run all tests with minitest?

Here's a link to Rake::TestTask.

There is an example in the page to get you started.

I'll post another one that I'm using right now for a gem:

require 'rake/testtask'

Rake::TestTask.new do |t|
  t.pattern = "spec/*_spec.rb"
end

As you can see, I assume that my files are all in /lib and that my specs are in /spec and are named whatever_spec.rb

Hope it helps.

Globbing doesn't work with Minitest - Only one file is run

This is not minitest specific, but Ruby. You are effectively running a ruby program which knows nothing about the program being run.

Ruby does not support running multiple files at once afaik, so if you want to get a similar result you could try something like:

for file in spec/**/*_spec.rb; do ruby $file; done

UPDATE: for what you want you should probably create a Rake task as described here
