The TCID and TST_TOTAL global variables are externed in the library, and MUST be defined/initialized by tests using the library. TCID must be set to the Test Case IDentifier, and TST_TOTAL must be set to the total number of test cases that will be reported.

The other global variables are available as externs to tests linked with tst_res.o. tst_count is the running count of the number of test results that have been reported so far. The library initializes it to 0, and it should not be modified by the test. The details are described below under the appropriate functions.

tst_brk() and tst_brkm() are used to report results for all test cases remaining in the test, and then call a cleanup function. The only result types that are valid for these functions are: TFAIL, TBROK, and TCONF. When called with a ttype of TFAIL or TBROK, one result of the specified ttype will be printed, followed by results of type TBROK for the remaining test cases. When called with a ttype of TCONF, the specified ttype will be printed for all remaining test cases. If func is not NULL, tst_brk() and tst_brkm() will call func after all results have been printed. If the call to func returns, tst_brk() and tst_brkm() will then call tst_exit(). If func is NULL, tst_brk() and tst_brkm() return to the caller after all results have been printed. If tst_brk() is called with a fname argument, the contents of the file will only be printed for the first reported result. tst_brk() takes the fname argument whereas tst_brkm() does not.

tst_old_flush() is used to print any results pending because of CONDENSE or NOPASS modes (described below), and flushes the output stream.

tst_exit() is used to allow tests to exit with a meaningful exit value. A bit is set in the exit value for each of the non passing test case result types (TFAIL, TBROK, and TWARN) encountered by the library. Thus any bit which is set in the exit value indicates that the corresponding result flag was used at least once in the test run.

The current bit fields for the result types are as follows:

NOTE: TPASS and TINFO do not have an effect on the test program exit status.

tst_environ() is used to ensure that results reported by this library will go to the original stdout, even if the test changes the original stdout to another file, or closes it. A test may want to do this in order to redirect output that normally goes to stdout (e.g. printf() output) to a file. tst_environ() returns 0 upon successful completion, and -1 if it encountered any problems.

#include "test.h"

char *TCID = "tsttcs01"; /* set test case identifier */
int TST_TOTAL = 15; /* set total number of test results */

main()
{
 .
 .
 /* a successful test result */
 tst_resm(TPASS, "what was tested");
 .
 .

 /* break all remaining test results */
 tst_brkm(TBROK, cleanup, "what didn't work");
 /* or */
 tst_brk(TBROK, file, cleanup, "what didn't work");
 .
 .

 /* exit after all test results have been passed to tst_res */
 tst_exit();
}

Sample output:

tsttcs01 1 PASS : Able to create MAXUP processes
tsttcs01 2 FAIL : Too many processes (MAXUP+1) created
tsttcs01 3 BROK : tabinfo(PROCTAB, &tbs) failed; errno = 13: Permission denied
