We will present many hard-to-test c++ idioms and multiple refactorings for making the code testable. Students who need to test and refactor legacy C++ code as they transition to test-driven development, will learn techniques to help them do this work safely and with minimal changes in the performance. We’ll cover several legacy idioms in which code is initially not accessible by tests. We’ll fix these and other testability problems with refactorings like “Extract Method” or “Extract Class”, and C++-specific techniques involving the preprocessor, “friend”, and changing access Levels.
