Everyone calls them mocks. They're not all mocks. Dummy, Stub, Spy, Mock, Fake — these five types of test doubles serve different purposes, and using the wrong one produces tests that either verify nothing or are so tightly coupled to implementation that they break every refactor. Key Takeaways "
Testing Strategy
Your coverage report says 85%. Your lead developer feels good. Then someone removes the assert from a critical test — coverage stays at 85%, but that test now catches nothing. Coverage measures how much code your tests run. It doesn't measure whether your tests would actually catch a bug.
Testing Strategy
You just deployed. Before your QA team runs four hours of regression tests, there's one question worth asking: is the build even worth testing? Smoke tests answer that in five minutes — and save everyone from discovering the login page is broken two hours into a full test run.
Testing Strategy
You fixed a bug last Tuesday. Today a customer reports the exact same bug is back. This is a regression — and it's the most preventable type of production failure. Regression testing is your memory: it remembers every bug you've ever fixed and makes sure it stays
Testing Strategy
Your developers say the feature is done. Your product manager says it's wrong. The spec was clear — they just interpreted it differently. BDD exists to eliminate that conversation by forcing everyone to agree on what "done" means before a line of code is written. Key Takeaways
Testing Strategy
Unit tests said everything worked. Integration tests agreed. Then your payment flow broke in production because the date picker component and the checkout API had a timing issue that only manifested in a real browser. E2E tests are the only tests that can catch what no other test can. Key
Testing Strategy
Your unit tests all pass. Every function works in isolation. Then you deploy and discover that your user service returns IDs as strings, but your order service expects integers. Integration testing is the only layer that catches what happens when your units meet reality. Key Takeaways Integration tests validate interactions
