Minitest::PowerAssert

A Power Assert implementation for Minitest. This gem is inspired by the test-unit-power_assert gem.

Installation

Add this line to your application's Gemfile:

gem 'minitest-power_assert'

And then execute:

$ bundle

Or install it yourself as:

$ gem install minitest-power_assert

Usage

see testcase

Basic Testcase

The minitest-power_assert gem overrides the #assert method. In order to use power assert, call the assert method with a block:

class TestPowerAssert < Minitest::Test
  def test_power_assert_failed
    assert { "0".class == "3".to_i.times.map {|i| i + 1 }.class }
  end
end

If the test above fails, it displays a test result with detailed information about variables:

  1) Failure:
TestPowerAssert#test_power_assert_failed [test/test_power_assert.rb:10]:
    assert { "0".class == "3".to_i.times.map {|i| i + 1 }.class }
                 |            |    |     |                |
                 |            |    |     |                Array
                 |            |    |     [1, 2, 3]
                 |            |    #<Enumerator: 3:times>
                 |            3
                 String
