This change series allow automatic testing for properties that usually can only be validated manually once the whole system is put together.

Habit: Split Services 1 – Ports and Adapters

Organization ROI: Reduce cost of ownership related to both 1st and 3rd party dependencies. Engineer ROI: Isolate and micro-test interactions between any two components. Get informed when 3rd party components change underneath you in production.

Habit: Test Temporal Dependencies

Organization ROI: Prevent timing-related bugs. Engineer ROI: Know when code will behave differently under delays, timeouts, and parallelism, even when you can't test all cases.
