# Minitest for Crystal
Unit tests and assertions for the Crystal programming language, using the
fantastic [minitest](https://github.com/seattlerb/minitest) as reference.
## Getting Started
Given that you'd like to test the following class:
```crystal
class Meme
def i_can_has_cheezburger?
"OHAI!"
end
def will_it_blend?
"YES!"
end
end
```
### Unit Tests
Define your tests as methods beginning with `test_`:
```crystal
require "minitest/autorun"
class MemeTest < Minitest::Test
def meme
@meme ||= Meme.new
end
def test_that_kitty_can_eat
assert_equal "OHAI!", meme.i_can_has_cheezburger?
end
def test_that_it_will_not_blend?
refute_match /^no/i, meme.will_it_blend?
end
def test_that_will_be_skipped
skip "test this later"
end
end
```
### Specs
Specs follow the same
[design rationale](https://github.com/seattlerb/minitest/blob/master/design_rationale.rb)
as the original Minitest: `describe` generates classes that inherit from
Minitest::Spec, and `it` generates test methods.
```crystal
require "minitest/autorun"
describe Meme do
let(:meme) { Meme.new }
describe "when asked about cheeseburgers" do
it "must respond positively" do
meme.i_can_has_cheezburger?.must_equal("OHAI!")
end
end
describe "when asked about blending possibilities" do
it "won't say no" do
meme.will_it_blend?.wont_match(/^no/i)
end
end
end
```
You may use assertions in your specs (they'll work the same) or you may prefer the `expect` syntax:
```crystal
expect(meme.i_can_haz_cheezeburger?).must_equal("OHAI!")
expect(meme.will_it_blend?).wont_match(/^no/i)
```
### Run Tests
Eventually run the tests:
```
$ crystal run test/meme_test.cr spec/meme_spec.cr -- --verbose
```
You may filter your tests using an exact test name, or a regexp:
```
$ crystal run test/meme_test.cr -- -n test_that_kitty_can_eat
$ crystal run test/meme_test.cr -- -n /will/
```
When using Minitest::Spec with assertions or the `expect` syntax, you can avoid to taint Object with all the `#must_` and `#wont_` expectations:
```
$ crystal run -Dmt_no_expectations spec/meme_spec.cr
```
