Learn the difference between manual and automated testing, the various types like unit and integration, and why testing is crucial for product health.
TDD involves converting feature specifications into machine-readable tests before writing any implementation code.
An overview of the JavaScript testing ecosystem compares the all-in-one Jest framework with the combination of Mocha and Chai.
The Fibonacci sequence is introduced as the coding challenge, and the Red-Green-Refactor strategy is outlined for its implementation.
A step-by-step guide to writing unit tests for the Fibonacci function using Mocha's `describe` and `it` blocks and Chai's `expect` assertions.
The Fibonacci function is implemented incrementally, running the test suite after each change to watch the tests turn from red to green.
An explanation of why the recursive implementation is slow for large inputs and how to solve precision issues using JavaScript's `BigInt`.
The workshop transitions from unit testing to integration testing by setting up an Express.js API and using SuperTest to define its behavior via tests.
Learn to write API tests with SuperTest and discover why making real network requests to external services makes your test suite slow and unreliable.
Use Sinon.js to mock modules and Nock.js to mock HTTP requests, effectively isolating your tests and making them significantly faster.
A summary of key takeaways, including a discussion on what to test in frontend applications and how to introduce TDD to junior developers.
