# MouseMelon a.k.a. Mexikan Gherkin

MouseMelon is a pseudo-Gherkin DSL designed to be used in RSpec acceptance specs but it may be used elsewhere.

## Notable features:

* It runs inside RSpec (Minitest support may come later): just include module and you're ready.
* `Given`, `When`, `Then` are just methods which calls the step definitions directly.
* You can use symbols `I_am_registered_user` or feature steps `I am registered user`.
* You can define the steps globally, locally or mix them into the specs.
* Steps can have arguments `I register user`.
* Command line tool to generate step definitions.
* No fancy output of tested steps like Cucumber or Spinach.

### Currently supported/tested environment:

* RSpec 3.3.x
* Ruby 2.1.x

## Installation

Add this line to your application's Gemfile:

```ruby
gem 'mouse_melon'
```

And then execute:

$ bundle

Or install it yourself as:

$ gem install mouse_melon

Include it to RSpec helper

```ruby
RSpec.configure do |config|
config.include MouseMelon::DSL, :type => :feature
end
```

## Usage

Here is demonstration of various possible styles:

```ruby
feature 'MouseMelon features' do
# Steps shared via modules
include CommonSteps

scenario 'Steps as methods' do
given_is_defined
when_is_defined
then_is_defined
end

scenario 'Steps as symbols' do
Given :given_is_defined
When :when_is_defined
Then :then_is_defined
end

scenario 'Steps as strings' do
Given 'given is defined'
When 'when is defined'
Then 'then is defined'
And 'and is defined'
And 'and it has arguments', 'hello', 1
end

scenario 'Steps as Steps' do
Step 'given is defined'
Step 'when is defined'
Step 'then is defined'
end

scenario 'Steps as triangle bullets' do
‣ 'given is defined'
‣ 'when is defined'
‣ 'then is defined'
end

scenario 'Steps as circle bullets' do
• 'given is defined'
• 'when is defined'
• 'then is defined'
end

# INLINE STEP DEFINITIONS

def given_is_defined
puts 'GIVEN'
end

def when_is_defined
puts 'WHEN'
end

step 'then is defined' do
puts 'THEN'
end

step 'and is defined' do
puts 'AND'
end

step 'and it has arguments' do |*args|
puts "AND with args #{args.inspect}"
end
end
```

For more examples look inside `examples` and `spec` folders.
