const implement = require("implement")

// LIFO.
function Queue() {}
Queue.prototype = {
offer: function (e) {},
poll: function () {},
peek: function () {}
}

// Queue backed by array.
function ArrayQueue() {}
ArrayQueue.prototype = {
offer: function (e) {},
poll: function () {},
peek: function () {}
}

// FIFO.
function Stack() {}
Stack.prototype = {
peek: function () {},
pop: function () {},
push: function () {}
}


describe("implement", function () {
it("should not throw error when implementing interface", function (done) {
implement(ArrayQueue, Queue)
done()
})

it("Should throw error when not implementing interface", function (done) {
try {
implement(Stack, Queue)
} catch (error) {
console.log(error.message)
done()
}
})
})

`

Run
===

`bash
mocha test.js
``

Todo
===

- Automically update tests in this document. Usefull for other projects as well. Probably should make this a seperate module or something?
- Let it read jsdoc too and ensure types. This would be really cool? Use http://ariya.ofilabs.com/2014/04/tracking-javascript-annotations.html as baseline?
- Add test coverage. I assume it is 100% or close to this. Not that it really matters.
- Better documentation(generation).
