Spies

Spies comes with a Chai-expect plugin. To use it, HTML import the main_chai_expect.html file.

Example of basic usage:

// Test code
var _ = spies.Spies;
_.spy(object, 'fn');

object.fn(1);
object.fn();

expect(object.fn).calledWith(1).at.least(1);
expect(object.fn).called().at.least(2);

Asserting order:

var _ = spies.Spies;
_.spy(object, 'fn');

object.fn(1);
object.fn();

expect(object.fn).calledWith(1).before(object.fn).calledWith();
expect(object.fn).called().before(object.fn).calledWith();
