# Minitest::PowerAssert
[](https://rubygems.org/gems/minitest-power_assert)
[](https://travis-ci.org/hsbt/minitest-power_assert)
A Power Assert implementation for Minitest. This gem is inspired by the [test-unit-power_assert](https://github.com/k-tsj/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](https://github.com/hsbt/minitest-power_assert/blob/master/test/test_power_assert.rb)
### Basic Testcase
The `minitest-power_assert` gem overrides the `#assert` method. In order to use power assert, call the assert method with a block:
```ruby
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:
```shell
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
```
