  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.

  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.

Let’s see how we can use a mocking library like sinon to reduce and standardize the testing code.
