Adding Tests

Tests are located in unit_tests.c. They look like this:

You can add your own tests to unit_tests.c, following the same format. You do not need to do anything except write the function in this file and re-make. The new tests will be included in the test index and can be queried the same way.

Valid unit tests have the prototype

int foo(void)

and (normally) return the value returned by a call to the test function, which has the prototype:

int test(const char *fmt, ...)

How it works

The Makefile creates two copies of the unit test, one that replaces test with ft_printf, and one that replaces test with printf. Running the test compares the output and return value of these two functions.

nocrash tests

Tests that start with nocrash are specially handled by tester. They will automatically pass as long as ft_printf does not crash.
