PODon't sinon.js spys catch errors?

Body
copied!<p>So, I'm using mocha with chai to do my front-end testing, but I'm starting to incorporate sinon and really liking it. Except that testing throwing errors isn't working quite how the sinon docs seem to indicate.</p> <p>Basically, I've got this method:</p> <pre><code>create: function(bitString, collectionType) { var collection; switch(collectionType) { case 'minutesOfHour': collection = this.createMinutesOfHour(bitString); break; case 'hoursOfDay': collection = this.createHoursOfDay(bitString); break; case 'daysOfWeek': collection = this.createDaysOfWeek(bitString); break; case 'daysOfMonth': collection = this.createDaysOfMonth(bitString); break; case 'monthsOfYear': collection = this.createMonthsOfYear(bitString); break; default: throw new Error('unsupported collection type ' + collectionType); } return collection; }, </code></pre> <p>and I'm testing it with this expectation:</p> <pre><code>it('throws error if missing second arguement', function() { sinon.spy(factory, 'create'); factory.create(); expect(factory.create).to.have.thrown(); factory.create.restore(); }); </code></pre> <p>however, the error, which I'm try to test for, also seems to halt the execution of the test</p> <p><img src="https://i.stack.imgur.com/PIKo4.png" alt="error message"></p> <p>I'd thought sinon.spy would include some try / catch logic internally, spy.throw doesn't seem as useful without it.</p> <p><a href="http://sinonjs.org/docs/#spies" rel="noreferrer">http://sinonjs.org/docs/#spies</a></p> <p>Am I doing something wrong??</p>
