Project is In-Active
What is it?
Provides high-level/functional/acceptance test organization lingo, using 'Feature', Stories, 'Scenarios', 'Given/Then/When'.
Mocha-Cakes adds the following commands:
You can use these commands to describe your tests & specs, as well as mocha's BDD commands
afterEach OR mocha's TDD commands
Mocha-Cakes Commands Breakdown
Mocha-Cakes extends Mocha, by adding on helpful commands and print-outs for Acceptance Tests. (Given, When, Then, etc.)
Scenario (maps to describe)
Then (maps to it, but if first message argument is ommited, it'll be a describe)
I (maps to it but if first message argument is ommited, it'll be a describe)
GWTab commands can map to a describe if the message argument is ommited.
Given 'I am at home', -> # it's an it home.should.eql 'home' Given -> # it's a describe it 'is dark', -> outside.should.eql 'dark'
Grey-Box, System Tests
System (if it has a message it'll be an it, if not it'll be a describe with System label, useful for testing (grey box) system resources, database, not directly observable by Customer etc.)
Given -> System 'Logged Out', -> Then -> System -> it 'should log in', ->
Pretty Commands for Specs/Unit Tests
Describe (maps to describe used for things like filenames)
Describe 'lib/file.coffee' # filename describe '+copy()', -> it 'should copy files...', ->
Mocha-Cakes 0.7 added the
I command, to do things like:
Given -> I 'have a test', -> And 'I have another', -> Then -> I 'should be good', -> But 'make sure I am also', ->
require 'mocha-cakes' Feature "New Feature", "In order to use cool feature", "as a new user", "I want do include this", -> Scenario "Singing", -> voice = null Given "I am a good singing", -> When "I sing", -> voice = 'good' Then "it should sound good", -> voice.should.eql 'good'
Run this test using mocha command:
mocha test.coffee -R spec -r should --compilers coffee:coffee-script
What's going on?
Mocha-cakes gives you access to function names
"Feature", "Scenario" that wraps around mocha's
"Given", "When", "Then", "And", "But" wraps around mocha's
it(). (If first argument is omitted
Given -> it'll be a
Also bonus, "Describe" wraps around mocha's describe() also, that could be used at the start of spec files. It prints out in bolded blue header with
-R Spec. And
System() is a describe or it depending on if first argument is a string or callback.
So the above would output something like:
Feature: New Feature In order to use cool feature as a new user I want do include this Scenario: Singing ✓ Given: I am a good singing ✓ When: I sing ✓ Then: it should sound good ✓ sound good ✔ 1 tests complete (3ms)
How to Use
Mocha-Cakes provides GWT commands to mocha, and pretty prints it.
To use just:
- require 'mocha-cakes'
Then you will have access to the mocha-cakes commands Feature, Scenario, Given, When, Then, etc.
Also to see the pretty output, use the spec reporter
mocha acceptance_tests.coffee -R spec -r mocha-cakes --compilers coffee:coffee-script
require 'mocha-cakes' Feature "Big Buttons", "As a user", "I want big buttons", "So it'll be easier to use", -> Scenario "On Homepage", -> Given "I am a new user", -> When "I go to homepage", -> And "I scroll down", -> Then "I see big buttons", -> But "no small text", -> Given -> # Describe When "I scroll down more", -> And "I reach end of page", -> Then "all I see is big buttons", -> Describe 'test.spec.coffee', -> Scenario false, 'Skip Me', ->
* Remember, they're all either
Mix & Match
Also you could still mix-in regular mocha syntax
Feature "Mix & Match" -> Scenario 'Mix-in Mocha', -> Given "I'm using Mocha-Cakes", -> Then -> describe 'Also using regular mocha', -> I 'should be able to do this', -> true.should.be true it 'should work too', -> true.should.be true
Note you can also test asynchronous code with Mocha-Cakes passing a callback argument to any GWTabi command. (
done for example)
Feature "Async tests with Mocha-Cakes", -> Given "I want to test async code", -> When "I pass 'done' to GWT commands", -> Then "It should wait for 'done' to be done.", (done)-> done()
cd my_project npm install --save-dev mocha-cakes
Mocha Reporter Support
Mocha-Cakes was developed with the
-R spec in mind.
You can use Mocha-Cakes also with the
-R doc reporter.
All other reporters should function, but have not been tested.
If you have any questions, issues or comments, please leave them on mocha-cakes' github.
*Special Thanks* to TJ Holowaychuk for Mocha, awesome test framework.
