# Quality Commands
## `dcr test`
Runs tests.
```bash
dcr test # debug profile
dcr test --release # release profile
dcr test --debug # explicit debug
dcr test --help # detailed help
```
Before first use, initialize tests:
```bash
dcr test --init
```
This creates `tests/dcr_test.h` (framework) and `tests/test.c` (template).
What `dcr test` does:
1. Builds the project
2. Collects `tests/*.c` files (`.c` only, not `.cpp`)
3. Compiles and links each test file
4. Runs each test binary
5. Prints summary: TOTAL, PASS, SKIP, FAIL
6. Returns non-zero exit code on any FAIL
## `dcr fmt`
Formats C/C++ source files using `clang-format`.
```bash
dcr fmt
```
Processes: `src/**/*.{c,cpp,cxx,cc,h,hpp,hxx,hh}` and `tests/**/*.{c,cpp,cxx,cc,h,hpp,hxx,hh}`.
Uses `.clang-format` at the project root (if present), otherwise default clang-format style.
