These learning hours are specific for the C language. Some are about embedded techniques. Many are about a specific technique to take code with awkward dependencies and get it under test, which I call ‘Surgery’.

These learning hours and associated exercises are somewhat unpolished and experimental right now.

Working with C

• TDD a state machine
• TDD a lamp microcontroller
• Move the patient into the surgery
• Cover the patient with tests
• Refactor for testability
• Return the patient
