How not to test

Golo Roden

Chasing 100% test coverage won't save a poorly architected codebase. Discover why over-mocking hides bugs and how prototyping before TDD actually accelerates development.

#1 about 6 min

Discovering automated testing through early programming experiences

How initial exposure to programming often lacks any concept of automated testing.

#2 about 7 min

Recognizing poorly structured code masquerading as hard to test

Code that feels impossible to test generally indicates poor architecture rather than intrinsic testing difficulty.

#3 about 6 min

Avoiding the trap of testing private code for coverage

Accessing internal state via reflection or inheritance to artificially boost code coverage represents an anti-pattern.

#4 about 4 min

Understanding why total code coverage is a false metric

Chasing full coverage often forces meaningless assertions and unnecessarily blocks automated deployment pipelines.

#5 about 8 min

Evaluating the dangers of over-mocking in integration tests

Relying heavily on fakes and stubs can create a false sense of security that breaks in reality.

#6 about 3 min

Managing test infrastructure and ensuring strict state reset

Automating infrastructure setups for tests guarantees independent execution free from stale states.

#7 about 4 min

Handling inherent asynchronicity when testing UI view components

Effective UI component testing requires strategies to handle asynchronous transitions and logic execution.

#8 about 4 min

Navigating the complexity of cross-browser view regression tests

Managing the fragility and slow execution times of large-scale browser automation suites requires realistic scoping.

#9 about 3 min

Knowing when to bypass test-driven development during prototyping

Strict test-first approaches hinder proof-of-concept exploration and add overhead before clear designs exist.

#10 about 2 min

Adopting a pragmatic approach to reasonable software engineering tests

Prioritizing realistic testing efforts yields better software quality than chasing arbitrary perfectionism or edge cases.
