  • Adding mocha unit tests

    In this post, I’ll add unit tests to the example application that I’ve been fiddling around with in the recent posts.

  • Using sinon mocks

    In the previous posts we had a look at sinon spies and stubs. There is one more technique we can use in order to orchestrate our test dependencies: mocks.

  • Using sinon stubs

    In the previous post we had a look at sinon spies. With spies, we are able to determine if a specific function was called or not. Usually the dependencies between units are more interesting, they involve units co-operating, exchanging data and so on. Spies do not suffice. Let’s have a look at another technique, using stubs.

  • Using sinon spies

    In the previous post, we implemented a new feature for our calculator: it makes a bell sound when you divide by zero. The bell is a simple function that the calculator calls and it is provided as a constructor dependency. We wrote a unit test for this as well, but the code for that is a bit verbose. Let’s see how we can use a mocking library like sinon to reduce and standardize the testing code.
