PCUT: Plain C Unit Testing

PCUT is a very simple framework for unit testing of C code. Unlike many other frameworks where you need to specify manually which functions belong to a particular test, PCUT provides several smart macros that hides this and lets you focus on the most important part of testing only: that is, coding the test cases.

Tests for the standard atoi() function may look like this:

#include < pcut/pcut.h >
#include < stdlib.h >

PCUT_INIT

PCUT_TEST(atoi_zero) {
PCUT_ASSERT_INT_EQUALS(0, atoi("0"));
}

PCUT_TEST(atoi_positive) {
PCUT_ASSERT_INT_EQUALS(42, atoi("42"));
}

PCUT_TEST(atoi_negative) {
PCUT_ASSERT_INT_EQUALS(-273, atoi("-273"));
}

PCUT_MAIN()
