Learn to confidently test JavaScript applications and mock dependencies using Jest, the pain-free way.
Understand how to painlessly use Mocks, Spies, and Stubs to test any part of your application, without worrying about Databases, APIs and Security Tokens.
After finishing this course (which only takes a single afternoon), you’ll feel confident in your testing skills because you’ll have all the knowledge and tools you need to effectively and painlessly test even complex applications in the real world without headaches.
WHAT YOU WILL LEARN
- How to write unit and integration tests with Jest
- How to test functions that interact with Controllers, APIs, and Databases (without relying on their responses)
- How to test code in isolation with Mocks, Spies, and Stubs using Mockingoose
- How to write integration tests for HTTP endpoints and database connections
- Advanced mocking and integration testing techniques like the 3A pattern, network manipulation, and more
- How to become a test strategist with the Agile Testing Quadrant, create CI test pipelines, and add tests to the development lifecycle
