A simple C test "framework".
Not really for production, but if all you need is lightweight, this is lightweight.
OK: test_adder: demo.c:22: adder(1, 2) == 3: testing common case
FAIL: test_adder: demo.c:23: adder(0, 1) == 1: testing zero
OK: test_adder: demo.c:24: adder(-2, 6) == 4: testing negatives
OK: test_subtractor: demo.c:29: subtractor(2, 1) == 1: testing common case
OK: test_subtractor: demo.c:30: subtractor(0, 1) == -1: testing zero
OK: test_subtractor: demo.c:31: subtractor(-2, 6) == -8: testing negatives
Results: 5/6 passing (83.3%).
To use:
#include <ctest.h>in the file with the tests.- Compile with
-DCTEST_ENABLE.
The ctest.h header file defines a number of macros, all of which are
optional.
| Macro | Description |
|---|---|
CTEST_ASSERT(cond, message) |
The workhorse. The test fails if the Boolean condition cond is false and the message is printed. |
CTEST_RESULTS() |
Print a results summary. |
CTEST_VERBOSE(on) |
If set to true, all tests and results are printed. Otherwise only the failing tests are printed. Default: false. |
CTEST_COLOR(on) |
Output in color. Default: true. |
CTEST_EXIT() |
Exit with status 1 if any tests have failed. Otherwise exit with status 0. |
See the Makefile and demo.c.
The ctest.h header file acts inappropriately and defines a number of
global variables of external linkage. All of these begin with ctest_.
But this allows it to keep stats and doesn't require another file to be linked in.
