# Features
|
||||
|
||||
* Easy to use, no dependencies, no setup needed.
|
||||
* Keep test cases close to the code they test.
|

* Automatic registration of the test cases.

To enable the test cases in your code, compile your program with `-DUNIT_TEST`.

## Run the test cases
|

|

In your main function, call `run_tests`:
|
||||
Build your program with `-DUNIT_TEST`, then run your program with `./program --unittest`.
|
||||
|
||||
```c
|
||||
int main(int argc, char *const *argv) {
|
||||
// necessary setup code
|
||||
// ...
|
||||
if (!run_tests(argc, argv, NULL)) {

// test failed

abort();

}

// cleanup
|
||||
// usual code
|
||||
}
|
||||
# Hooks
|
||||
|
||||
```
|
||||
|
||||
Then, run your program with `./program --unittest`.
|
||||
If you define a function `test_h_unittest_setup`, it will be called before any test cases are run.
