quickstart

1: Describe behavior in plain text

Feature: Addition
  In order to avoid silly mistakes
  As a match idiot
  I want to be told the sum of two numbers

  Scenario: Add two numbers
    Given I have entered 50 into the calculator
    and I have entered 70 into the calculator
    When I press add
    Then the result should be 120 on the screen

2: Run and get the template for a step definition file

peanut features/example.feature

Running features

Unimplemented: 3

Given(/^I have entered (\d*\.)?(\d+) into the calculator$/, function(step, arg) {
  step.pending();
});

When(/^I press add$/, function(step) {
  step.pending();
});

Then(/^the result should be (\d*\.)?(\d+) on the screen$/, function(step, arg) {
  step.pending();
});

3: Write a step definition in Javascript

var assert = require('assert')
var calculator = require('../support/calculator')

Given(/^I have entered (\d*\.)?(\d+) into the calculator$/, function(step, arg) {
  calculator.push(parseInt(arg))
  step.done()
})

When(/^I press add $/, function(step) {
  step.pending()
})

Then(/^the result should be (\d*\.)?(\d+) on the screen$/, function(step, arg) {
  step.pending()
})

4: Run and watch it fail

peanut features/example.feature

module.exports = (function() {
  var args = []

  return {
    push: function(arg) {
      args.push(arg)
    }
  }
})()
