Mocha / Chai expect.to.throw not catching thrown errors

Question

I\'m having issues getting Chai\'s expect.to.throw to work in a test for my node.js app. The test keeps failing on the thrown error, but If I wrap the test case

Answer 1

One other possible implementation, more cumbersome than the .bind() solution, but one that helps to make the point that expect() requires a function that provides a this context to the covered function, you can use a call(), e.g.,

expect(function() {model.get.call(model, 'z');}).to.throw('...');
