Returns a deep copy of an object with all functions converted to spies
npm install 007Returns a deep copy of an object with all functions converted to spies.
Install with npm:
``
npm install 007
`
// we want to test github
var github = require('github');
var doubleOhSeven = require('007');
var mockGithub = doubleOhSeven(github);
mockGithub.pullRequests.getCommits.returns = function () {
return {
foo: 'beep'
};
};
assert(mockGithub.pullRequests.getCommits('lalala').foo === 'beep');
assert(mockGithub.pullRequests.getCommits.callCount === 1);
`
Takes an object or function as an argument, returns a function or object matching the original, but with mocked out functions.
The implementation of the mock function.
Set with =:
Ex:
`
mockFn.implementation = function (val, cb) {
return cb(val + 1);
};
The following functions are helpers for implementation; using them will override mockFn.implementation.
#### mockFn.returns()
The return value of the mock.
Ex:
`
mockFn.returns('foo');
mockFn(function (arg) {
console.log(arg); // outputs 'foo'
});
#### mockFn.callbackArgs
The callback args to be invoked by the mock.
Ex:
`
mockFn.callbackArgs(['foo']);
mockFn(function (arg) {
console.log(arg); // outputs 'foo'
});
