It was +developed as a tool for testing musl and its first-generation +predecessor. As such, most of the tests were written to be +self-contained and not to make assumptions about other library +interfaces being present or working correctly. + +At present the whole testsuite builds as a single binary and runs as a +single process (aside from a few child processes that are part of the +tests). This makes it extremely fast, but also means that corruption +of the global state due to bugs in one set of interfaces may affect +later tests. If necessary, the main test dispatch module could be +modified to fork before running each test, ensuring that each one +begins with a clean working state. + + +Building and running the tests + +If needed, a file named config.mak can be created to override the +default CC, CFLAGS, etc. used by the build process. Otherwise, simply +run "make" in the libc-testsuite directory to build the tests. Then +run "./testsuite" or "make test" to run the tests. + +The following additional CFLAGS options may be of interest: + +-DHAVE_BSD_STRL - tests the BSD strlcpy and strlcat functions. +-DDISABLE_SLOW_TESTS - disables testing 2GB snprintf. + diff --git a/basename.c b/basename.c new file mode 100644 index 0000000..2f0ee2a --- /dev/null +++ b/basename.c @@ -0,0 +1,30 @@ +#include <stdio.h> +#include <string.h> +#include <libgen.h> +#include <stdlib.h> + +#define TEST(p, b) ( \ +tmp = strdup((p)), s = basename(tmp), \ +!strcmp((b),s) || \ +(printf(__FILE__ ":%d: basename(\"%s\") returned \"%s\";
