C++ Test-driven Development
summary
Concrete claim: test-driven cycles produce simpler, safer C++ and refactoring speeds up with IDE help. Demonstrations use Eclipse CDT and Cevelop tooling to auto-generate code from tests, run unit tests until green bar, and refactor with an extract function operation. Examples build a testable hello world, a switch class and an expression evaluator, showing failing tests turned green and a ~1:1 to 1:2 ratio of test to product lines. Tools include ostringstream substitution for IO testing.
