Testing Applications - How to Do It Better?
summary
Practical guidance on testing applications: focus tests where they add real value (after bugs, for new features, and before refactors), prefer small readable tests with clear names, hide complex Given setups, and use assert-object patterns. Recommends choosing classical or London mock styles per module, use Mockito for mocks, keep tests fast (FIRST, target 1s/10s/30s feedback thresholds), run tests on CI, and add temporary higher-level integration tests to make safe refactoring easier.
