This module is a demonstration of basic testing methods in Node. It also covers rewire and spies. This part is not clear.

Featured Libraries

1. Mocha 3.0.0 - test framework
2. Expect 1.20.2 - assertion library
3. Supertest 2.0.0 - for testing http requests
4. Rewire 2.5.2 - dependency injection

Notes

1. Mocha is not required in a test file. It is used to run tests and define test files - see package.json. It provides the describe and it structure.
2. The basic structure of an expect assertion is expect().toBe()
3. Supertest allows us to make request of the app through a particular route and then expect a particular response. Note that we pass in done to make the test asynchronous.
