The full test suite is controlled with -the testall program. At the beginning of the testall.c file, there is an -array of functions called tests. The testall program loops through this -array calling each function. Each function returns a CuSuite variable, which -is then added to the SuiteList. Once all Suites have been added, the SuiteList -is executed, and the output is printed to the screen. All functions in the -array should follow the same basic format: - -The Full Suite --------------- - -/* The driver function. This must return a CuSuite variable, which will - * then be used to actually run the tests. Essentially, all Suites are a - * collection of tests. The driver will take each Suite, and put it in a - * SuiteList, which is a collection of Suites. - */ -CuSuite *testtime(void) -{ - /* The actual suite, this must be created for each test program. Please - * give it a useful name, that will inform the user of the feature being - * tested. - */ - CuSuite *suite = CuSuiteNew("Test Time"); - - /* Each function must be added to the suite. Each function represents - * a single test. It is possible to test multiple features in a single - * function, although no tests currently do that. - */ - SUITE_ADD_TEST(suite, test_now); - SUITE_ADD_TEST(suite, test_gmtstr); - SUITE_ADD_TEST(suite, test_localstr); - SUITE_ADD_TEST(suite, test_exp_get_gmt); - SUITE_ADD_TEST(suite, test_exp_get_lt); - SUITE_ADD_TEST(suite, test_imp_gmt); - SUITE_ADD_TEST(suite, test_rfcstr); - SUITE_ADD_TEST(suite, test_ctime); - SUITE_ADD_TEST(suite, test_strftime); - SUITE_ADD_TEST(suite, test_strftimesmall); - SUITE_ADD_TEST(suite, test_exp_tz); - SUITE_ADD_TEST(suite, test_strftimeoffset); - - /* You must return the suite so that the driver knows which suites to - * run. - */ - return suite; -} - -Building the full driver ------------------------- - -All you need to do to build the full driver is run: - - make testall - -To run it, run: - - ./testall - -Caveats -------- - -Currently, some tests are known to fail in certain circumstances: - - * 'testpoll' opens 64 sockets concurrently; ensure that resource -limits are high enough to allow this (using ulimit or limit); for -instance, Solaris <=2.7 and HP-UX 11.00 both set the limit to <=64 by -default - - * 'testipsub' will tickle the Solaris 8 getaddrinfo() IPv6 -bug, causing the test to hang. Configure with --disable-ipv6 if using -an unpatched Solaris 8 installation. - - * The 'testdso' tests will not work if configured with ---disable-shared since the loadable modules cannot be built. - -Running individual tests ---------------------------------- - -It is not possible to build individual tests, however it is possible to -run individual tests. When running the test suite, specify the name of the -tests that you want to run on the command line. For example: - - ./testall teststr testrand - -Will run the Strings and Random generator tests. - -Reading the test suite output ------------------------------ - -Once you run the test suite, you will get output like: - -All APR Tests: - Test Strings: .... - Test Time: ............ - -16 tests run: 16 passed, 0 failed, 0 not implemented. - -There are a couple of things to look at with this. First, if you look at the -first function in this document, you should notice that the string passed to -the CuSuiteNew function is in the output. That is why the string should -explain the feature you are testing. - -Second, this test passed completely. This is obvious in two ways. First, and -most obvious, the summary line tells you that 16 tests were run and 16 tests -passed. However, the results can also be found in the lines above. Every -'.' in the output represents a passed test. - -If a test fails, the output will look like: - -All APR Tests: - Test Strings: .... - Test Time: ..F......... - -16 tests run: 15 passed, 1 failed, 0 not implemented. - -This is not very useful, because you don't know which test failed. However, -once you know that a test failed, you can run the suite again, with the --v option. If you do this, you will get something like: - -All APR Tests: - Test Strings: .... - Test Time: ..F......... - -16 tests run: 15 passed, 1 failed, 0 not implemented. -Failed tests: -1) test_localstr: assert failed - -In this case, we know the test_localstr function failed, and there is an -Assert in this that failed (I modified the test to fail for this document). -Now, you can look at what that test does, and why it would have failed. - -There is one other possible output for the test suite (run with -v): - -All APR Tests: - Test Strings: .... - Test Time: ..N......... - -16 tests run: 15 passed, 0 failed, 1 not implemented. - -Not Implemented tests: - -Not Implemented tests: -1) test_localstr: apr_time_exp_lt not implemented on this platform - -The 'N' means that a function has returned APR_ENOTIMPL. This should be -treated as an error, and the function should be implemented as soon as -possible. - -Adding New test Suites to the full driver -------------------------------------------- - -To add a new Suite to the full driver, you must make a couple of modifications. - -1) Edit test_apr.h, and add the prototype for the function. -2) Edit testall.c, and add the function and name to the tests array. -3) Edit Makefile.in, and add the .lo file to the testall target. - -Once those four things are done, your tests will automatically be added -to the suite. - -Writing tests -------------- - -There are a couple of rules for writing good tests for the test suite. - -1) All tests can determine for themselves if it passed or not. This means -that there is no reason for the person running the test suite to interpret -the results of the tests. -2) Never use printf to add to the output of the test suite. The suite -library should be able to print all of the information required to debug -a problem. -3) Functions should be tested with both positive and negative tests. This -means that you should test things that should both succeed and fail. -4) Just checking the return code does _NOT_ make a useful test. You must -check to determine that the test actually did what you expected it to do. - -An example test ---------------- - -Finally, we will look at a quick test: - -/* All tests are passed a CuTest variable. This is how the suite determines - * if the test succeeded or failed. - */ -static void test_localstr(CuTest *tc) -{ - apr_status_t rv; - apr_time_exp_t xt; - time_t os_now; - - rv = apr_time_exp_lt(&xt, now); - os_now = now / APR_USEC_PER_SEC; - - /* If the function can return APR_ENOTIMPL, then you should check for it. - * This allows platform implementors to know if they have to implement - * the function. - */ - if (rv == APR_ENOTIMPL) { - CuNotImpl(tc, "apr_time_exp_lt"); - } - - /* It often helps to ensure that the return code was APR_SUCESS. If it - * wasn't, then we know the test failed. - */ - CuAssertTrue(tc, rv == APR_SUCCESS); - - /* Now that we know APR thinks it worked properly, we need to check the - * output to ensure that we got what we expected. - */ - CuAssertStrEquals(tc, "2002-08-14 12:05:36.186711 -25200 [257 Sat] DST", - print_time(p, &xt)); -} - -Notice, the same test can fail for any of a number of reasons. The first -test to fail ends the test. - -CuTest ------- - -CuTest is an open source test suite written by Asim Jalis. It has been -released under the zlib/libpng license. That license can be found in the -CuTest.c and CuTest.h files. - -The version of CuTest that is included in the APR test suite has been modified -from the original distribution in the following ways: - -1) The original distribution does not have a -v flag, the details are always -printed. -2) The NotImplemented result does not exist. -3) SuiteLists do not exist. In the original distribution, you can add suites -to suites, but it just adds the tests in the first suite to the list of tests -in the original suite. The output wasn't as detailed as I wanted, so I created -SuiteLists. - -The first two modifications have been sent to the original author of CuTest, -but they have not been integrated into the base distribution. The SuiteList -changes will be sent to the original author soon. - -The modified version of CuTest is not currently in any CVS or Subversion -server. In time, it will be hosted at rkbloom.net. - -There are currently no docs for how to write tests, but the teststr and -testtime programs should give an idea of how it is done. In time, a document -should be written to define how tests are written. - |
