Learn to write unit tests in JavaScript with Mocha.
### Why Learn JavaScript Unit Testing?
Tests are essential for programmers! Errors in software are inevitable and costly. Testing enables programmers to catch more of their own bugs before deploying their code. Testing is so important that some developers write tests _before_ anything else, in a methodology known as test-driven development.
### Take-Away Skills:
You will learn the fundamentals of test-driven development, and the popular JavaScript testing library, Mocha. This course focuses on unit tests, which are the smallest and most specific types of software tests. After this course, you'll be ready to test larger software features with the course Learn Testing for Web Development.
### Note on Prerequisites:
Intermediate JavaScript is a prerequisite for this course. You should be comfortable with programming fundamentals, control flow, arrays, objects, and functions.
