Test Driven Development using Javascript and Jest

Ever wondered what Test-Driven Development (TDD) truly is? Dive in as we demystify this powerful approach through a hands-on coding challenge.

We’ll delve into the world of unit tests, uncovering their role in solving complex tasks in digestible chunks.

Join us as we construct a ‘Game of Life’ simulation with a twist: writing unit tests comes first.

We’ll use Jest to create these tests, piecing together our project in achievable steps until we bring it to life within a browser. Experience the pragmatism of TDD and unit testing firsthand, navigating this course as our co-driver.

Keep in mind that our approach may not cater to all tastes; we encourage you to explore a few free videos to see if we’re a match. Our focus is pure, unadulterated JavaScript – no React, no frameworks. We value your satisfaction, and would rather offer a refund than have you leave unsatisfied.

Many believe TDD to be a complex maze, but we’re here to show you its simplicity and elegance! Our course outline? We start with an end goal, like ‘construct a Game of Life’, then atomise it into manageable tasks. If you’ve worked in a software company, you’d recognise these as user stories. For every selected task, we’ll ask: “What tests would prove that this task functions as expected?” Then, the journey unfolds:

1. Dissect the task and enumerate the tests required for a ‘Done’ stamp
2. Heed Kent Beck’s advice – “start small or not at all”, by writing the simplest test and corresponding code to pass
3. Stub out dependencies
4. Gradually transition constants to variables, moving from specific to generic

Excited? Let’s turn complexity into simplicity, one test at a time!
