Stay up to date with practical insights on backend engineering, system design, and building reliable software.
Conditional dispatch — switching on a type or status to select behavior — is the most common source of rigid code in Java applications. The strategy pattern replaces the switch with polymorphism, but the right implementation depends on what varies and how often it changes.
Read moreWhen a unit test requires elaborate setup, deep mocking, or access to private internals just to exercise a simple behavior, the test is not the problem. The design is. Testability friction is design feedback.
