Feature: Simple maths
In order to do maths
As a developer
I want to increment variables
Scenario: easy maths
Given a variable set to 1
When I increment the variable by 1
Then the variable should contain 2
Scenario Outline: much more complex stuff
Given a variable set to <var>
When I increment the variable by <increment>
Then the variable should contain <result>
Examples:
| var | increment | result |
| 100 | 5 | 105 |
| 99 | 1234 | 1333 |
| 12 | 5 | 18 |
///// Your World /////
// set this.World to your custom world (optional)
var CustomWorld = function() {};
CustomWorld.prototype.variable = 0;
CustomWorld.prototype.setTo = function(number) {
this.variable = parseInt(number);
};
CustomWorld.prototype.incrementBy = function(number) {
this.variable += parseInt(number);
};
this.World = CustomWorld;
///// Your step definitions /////
// use this.Given(), this.When() and this.Then() to declare step definitions
this.Given(/^a variable set to (\d+)$/, function(number) {
this.setTo(number);
});
this.When(/^I increment the variable by (\d+)$/, function(number) {
this.incrementBy(number);
});
this.Then(/^the variable should contain (\d+)$/, function(number) {
if (this.variable != parseInt(number))
throw new Error('Variable should contain ' + number +
' but it contains ' + this.variable + '.');
});
