minitest-funcarg

This is an extension to minitest which adds the ability to use funcargs as a method of test-level isolation. Funcargs are a form of dependency injection.

WARNING: This is a proof of concept. It works, but is not intended -- in its current form -- to be used for production tests.

Example

Defining And Using Funcargs

Define a test class:

require "minitest/autorun"
require "minitest/unit"
require "minitest/funcarg"

class MyTest < MiniTest::Unit::TestCase
  def minitest_funcarg__number
    return 7
  end

  def test_things(number)
    assert number > 0
  end
end

Run them:

$ ruby my_test.rb
Started
.
Finished in 0.000343 seconds.

1 tests, 1 assertions, 0 failures, 0 errors, 0 skips

The result is that the number parameter for test_things was given as the number 7 since that is what the magic method minitest_funcarg__number returned.
