Implementation of libc string.h functions with some additions, including ssprintf with all specifiers and flags. Fully covered with unit-tests under TDD approach.
Build & launching unit-tests
The goal of this project was to get comfortable with strings handling in C, explore tokenization and solidify our knowledge & skills of structured programming, while trying to replicate libc strings handling functions.
- Working with strings in C
- Functions with variable number of arguments
- Creating & linking static libs, building project with Makefile
- Unit-testing with Check framework, exploring TDD approach
- Exploring & evaluating test coverage with gcov
The most valuable discovery out of all of them is definitely TDD methodology. The experience of getting instant feedback by unit tests while writing sscanf was invaluable and kept me motivated during refactoring & bug fixes sessions.
