This is the test harness for libarchive.
It compiles into a single program "libarchive_test" that is intended
to exercise as much of the library as possible. It is, of course,
very much a work in progress.
Each test is a function named test_foo in a file named test_foo.c.
Note that the file name is the same as the function name.
Each file must start with this line:
#include "test.h"
The test function must be declared with a line of this form
DEFINE_TEST(test_foo)
Nothing else should appear on that line.
When you add a test, please update the Makefile to add your
file to the list of tests. The Makefile and main.c use various
macro trickery to automatically collect a list of test functions
to be invoked.
Each test function can rely on the following:
* The current directory will be a freshly-created empty directory
suitable for that test. (The top-level main() creates a
directory for each separate test and chdir()s to that directory
before running the test.)
* The test function should use assert(), assertA() and similar macros
defined in test.h. If you need to add new macros of this form, feel
free to do so.
* You are encouraged to document each assertion with a failure() call
just before the assert. The failure() function is a printf-like
function whose text is displayed only if the assertion fails. It
can be used to display additional information relevant to the failure:
failure("The data read from file %s did not match the data written to that file.", filename);
assert(strcmp(buff1, buff2) == 0);
* Tests are encouraged to be economical with their memory and disk usage,
though this is not essential.
* Disable tests on specific platforms as necessary. Please don't
use config.h to adjust feature requirements, as I want the tests
to also serve as a check on the configure process. The following
form is appropriate:
#if !defined(__PLATFORM) && !defined(__Platform2__)
assert(xxxx)
#endif
