If a routine under test uses promises at some point and catches any errors returning the result to the callback function, it's not possible to throw assert In this video I will show you how to setup the Mocha unit testing framework along with Chai which is an assertion library. I will also show you how to struct Se hela listan på github.com Chai can be paired with any javascript testing framework (for instance Mocha) Chai has several interfaces that allow the developer to choose. The chain-capable BDD styles provide an expressive language & readable style, while the TDD assert style provides a more classical feel.

Note the difference between mocha debug and mocha --debug: mocha debug will fire up node's built-in debug client, mocha --debug will allow you to use a different interface — such as the Blink Developer Tools.--globals [names] Accepts a comma-delimited list of accepted global variable names.

Mocha.js does not discriminate, regardless of which assertion library you choose to use. If you’re using Mocha in a Node.js environment, you can use the built-in assert module as your assertion library.

However, Mocha does not verify our code’s behavior. To compare values in a test, we can use the Node.js assert module.

The first argument to it is an explanation of the test case, and the second parameter is the test case function to which Mocha passes a done object.
