libzt3

Usage

Library

Library for unit testing C (-lzt)

Overview

The libzt library offers routines for writing C unit tests. It is focusing on simplicity, robustness and correctness, offering facilities for:

• Defining test suites and test cases.

• Asserting relations between booleans, integers, strings and characters. Asserting properties of booleans and pointers.

• Creating command line interface that allows enumerating and invoking tests. The output of test programs integrates well with make.

The library code is portable between a wide range of C compilers and operating systems. All library code is covered by a self-test test suite. The library never allocates memory or uses the file system which makes it suitable for working on embedded targets.

Examples

The following fragment demonstrates a simple test program, comprised of a single test suite with a single test case checking the relations between two integers.

#include <zt.h>
static void test_math(zt_t t)
{
    zt_check(t, ZT_CMP_INT(2 + 2, ==, 4));
}
static void test_suite(zt_visitor v)
{
    ZT_VISIT_TEST_CASE(v, test_math);
}
int main(int argc, char** argv, char** envp)
{
    return zt_main(argc, argv, envp, test_suite);
}
