What code testing strategies work best for different types of projects?

[Eric63]

I'm trying to improve our testing approach across different projects and I'm curious about what code testing strategies work best in various contexts. Do you use different approaches for web apps versus APIs versus mobile apps? How do software development methodologies influence your testing strategy? I'm looking for practical advice that balances thoroughness with development speed.

For code testing strategies, I use different approaches based on the project type. For web apps, I focus on integration tests that simulate user interactions. For APIs, contract testing and thorough unit tests of business logic. For mobile, I prioritize UI automation less because of flakiness and more manual testing. The key is balancing test coverage with maintenance cost.

Test pyramid thinking is crucial. Lots of fast, cheap unit tests at the bottom, fewer integration tests in the middle, and minimal end-to-end tests at the top. For different software development methodologies: Agile teams need fast feedback so prioritize tests that run quickly. Waterfall might allow more comprehensive testing phases. Always consider the feedback loop speed.

I've found that the most effective testing strategy is the one your team will actually maintain. Overly complex test setups get abandoned. Start simple: unit tests for complex logic, integration tests for critical paths. For legacy code, characterization tests to understand behavior before making changes. Also, test data management is often overlooked but critical for consistent results.
