Publisher's Synopsis
Confident Code Starts with Tests That Deliver
Tired of brittle tests? Tired of bugs slipping through? Automated Testing That Works teaches you how to build a rock-solid test suite that's easy to maintain, catches real problems, and empowers continuous delivery.
Whether you're a junior developer or a seasoned engineer, this practical guide walks you through the entire automated testing stack-from unit tests to integration to full end-to-end coverage-so you can build software that ships with confidence.
You won't just write tests. You'll learn how to test smart.
What You'll Learn:Core principles of automated testing (fast, reliable, isolated)
Writing unit tests that catch logic errors early
Creating integration tests that simulate real-world scenarios
End-to-end tests that validate the full user journey
Mocking, stubbing, and controlling side effects
Testing asynchronous flows, APIs, and databases
When (and when not) to test
Choosing the right tools: Jest, Mocha, JUnit, Cypress, Selenium, etc.
Designing a scalable test architecture for real-world teams
Integrating tests into CI/CD pipelines
From frontend to backend, from local dev to production-you'll gain the skills to test every layer of your stack without wasting time on fragile or flaky code.
Write less. Catch more. Ship faster.
