/// \file tuktest.h
|
||||
/// \brief Helper macros for writing simple test programs
|
||||
/// \version 2022-06-02
|
||||
///
|
||||
/// Some inspiration was taken from STest by Keith Nicholas.
|
||||
///
|
||||
/// This is standard C99/C11 only and thus should be fairly portable
|
||||
/// outside POSIX systems too.
|
||||
///
|
||||
/// This supports putting multiple tests in a single test program
|
||||
/// although it is perfectly fine to have only one test per program.
|
||||
/// Each test can produce one of these results:
|
||||
/// - Pass
|
||||
/// - Fail
|
||||
/// - Skip
|
||||
/// - Hard error (the remaining tests, if any, are not run)
|
||||
///
|
||||
/// By default this produces an exit status that is compatible with
|
||||
/// Automake and Meson, and mostly compatible with CMake.[1]
|
||||
/// If a test program contains multiple tests, only one exit code can
|
||||
/// be returned. Of the following, the first match is used:
|
||||
/// - 99 if any test returned a hard error
|
||||
/// - stdlib.h's EXIT_FAILURE if at least one test failed
|
||||
/// - 77 if at least one test was skipped or no tests were run at all
|
||||
/// - stdlib.h's EXIT_SUCCESS (0 on POSIX); that is, if none of the above
|
||||
/// are true then there was at least one test to run and none of them
|
||||
/// failed, was skipped, or returned a hard error.
|
||||
///
|
||||
/// A summary of tests being run and their results are printed to stdout.
|
||||
/// If you want ANSI coloring for the output, #define TUKTEST_COLOR.
|
||||
/// If you only want output when something goes wrong, #define TUKTEST_QUIET.
|
||||
///
|
||||
/// The downside of the above mapping is that it cannot indicate if
|
||||
/// some tests were skipped and some passed. If that is likely to
|
||||
/// happen it may be better to split into multiple test programs (one
|
||||
/// test per program) or use the TAP mode described below.
|
||||
///
|
||||
/// By using #define TUKTEST_TAP before #including this file the
|
||||
/// output will be Test Anything Protocol (TAP) version 12 compatible
|
||||
/// and the exit status will always be EXIT_SUCCESS. This can be easily
|
||||
/// used with Automake via its tap-driver.sh. Meson supports TAP natively.
|
||||
/// TAP's todo-directive isn't supported for now, mostly because it's not
|
||||
/// trivially convertible to the exit-status reporting method.
|
||||
///
|
||||
/// If TUKTEST_TAP is used, TUKTEST_QUIET and TUKTEST_COLOR are ignored.
|
||||
///
|
||||
/// The main() function may look like this (remember to include config.h
|
||||
/// or such files too if needed!):
|
||||
///
|
||||
/// #include "tuktest.h"
|
||||
///
|
||||
/// int main(int argc, char **argv)
|
||||
/// {
|
||||
/// tuktest_start(argc, argv);
|
||||
///
|
||||
/// if (!is_package_foo_available())
|
||||
/// tuktest_early_skip("Optional package foo is not available");
|
||||
///
|
||||
/// if (!do_common_initializations())
|
||||
/// tuktest_error("Error during common initializations");

/// tuktest_run(testfunc2);
|
||||
///
|
||||
/// return tuktest_end();
|
||||
/// }
|
||||
///
|
||||
/// Using exit(tuktest_end()) as a pair to tuktest_start() is OK too.
|
||||
///
|
||||
/// Each test function called via tuktest_run() should be of type
|
||||
/// "void testfunc1(void)". The test functions should use the
|
||||
/// various assert_CONDITION() macros. The current test stops if
|
||||
/// an assertion fails (this is implemented with setjmp/longjmp).
|
||||
/// Execution continues from the next test unless the failure was
|
||||
/// due to assert_error() (indicating a hard error) which makes
|
||||
/// the program exit() without running any remaining tests.
|
||||
///
|
||||
/// Search for "define assert" in this file to find the explanations
|
||||
/// of the available assertion macros.
|
||||
///
|
||||
/// IMPORTANT:
|
||||
///
|
||||
/// - The assert_CONDITION() macros may only be used by code that is
|
||||
/// called via tuktest_run()! This includes not only the function
|
||||
/// named in the tuktest_run() call but also any functions called
|
||||
/// further from there. (The assert_CONDITION() macros depend on setup
|
||||
/// code in tuktest_run() and other use results in undefined behavior.)
|
||||
///
|
||||
/// - The limitations goes the other way too: Functions and macros
|
||||
/// other than the assert_CONDITION() macros must not be used in
|
||||
/// the tests called via tuktest_run().
