| | | - `res.body.should.be.instanceof(Array);` is the actual test call |
|---|
| | | - `done();` tells the test runner that `mocha` has finished execution. This is needed as the http calls are asynchronous. |

| | | 3. With this knowledge; let's implement our test for the `important` flag. We expect the fronted to introduce a new property on each `todo` that gets passed to the backend called `important`. The API will need to handle this new property and pass it into the mongodb. Let's begin implementing this functionality by writing our test case. Navigate to the `PUT /api/todos` section of the `server/api/todo/todo.spec.js` test file (which should be at the bottom) |

| | | > Using [Jest](https://facebook.github.io/jest/) as our test runner and the `vue-test-utils` library for managing our vue components; we will now write some tests for frontend functionality to persist our important-flag. The changes required to the front end are quite large but we will use TDD to create our test first, then implement the functionality. |

| | | Our TodoList App uses `vuex` to manage the state of the apps' todos and `axios` HTTP library to connect to the backend. `Vuex` is an opinionated framework for managing application state and has some key design features you will need to know to continue with the exercise. |
