From Problem to Solution
summary
A concrete technique: replace a monstrous network class with a composable Transport protocol that has one send method, then build wrappers for checking status codes, header injection, authentication, background tasks, counters and timing. The talk shows test helpers like a mock transport and an inspector, a generic decode extension for promises, and measures the problem (96 possible test paths) to argue the new stack is shorter, decoupled, testable and reusable.
