For SSL tests, it runs stunnel to handle encryption to the regular servers. For SSH, it runs a standard OpenSSH server. For SOCKS4/5 tests SSH is used to perform the SOCKS functionality and requires a SSH client and server. The base port number shown above can be changed using runtests' -b option to allow running more than one instance of the test suite simultaneously on one machine. Run: 'make test'. This builds the test suite support code and invokes the 'runtests.pl' perl script to run all the tests. Edit the top variables of that script in case you have some specific needs, or run the script manually (after the support code has been built). The script breaks on the first test that doesn't do OK. Use -a to prevent the script from abort on the first error. Run the script with -v for more verbose output. Use -d to run the test servers with debug output enabled as well. Specifying -k keeps all the log files generated by the test intact. Use -s for shorter output, or pass test numbers to run specific tests only (like "./runtests.pl 3 4" to test 3 and 4 only). It also supports test case ranges with 'to', as in "./runtests 3 to 9" which runs the seven tests from 3 to 9. Any test numbers starting with ! are disabled, as are any test numbers found in the file data/DISABLED (one per line). Shell startup scripts: Tests which use the ssh test server, SCP/SFTP/SOCKS tests, might be badly influenced by the output of system wide or user specific shell startup scripts, .bashrc, .profile, /etc/csh.cshrc, .login, /etc/bashrc, etc. which output text messages or escape sequences on user login. When these shell startup messages or escape sequences are output they might corrupt the expected stream of data which flows to the sftp-server or from the ssh client which can result in bad test behaviour or even prevent the test server from running. If the test suite ssh or sftp server fails to start up and logs the message 'Received message too long' then you are certainly suffering the unwanted output of a shell startup script. Locate, cleanup or adjust the shell script. Memory: The test script will check that all allocated memory is freed properly IF curl has been built with the CURLDEBUG define set. The script will automatically detect if that is the case, and it will use the ../memanalyze script to analyze the memory debugging output. The -t option will enable torture testing mode, which runs each test many times but causes a different memory allocation to fail on each successive run. This tests the out of memory error handling code to ensure that memory leaks do not occur even in those situations. Debug: If a test case fails, you can conveniently get the script to invoke the debugger (gdb) for you with the server running and the exact same command line parameters that failed. Just invoke 'runtests.pl <test number> -g' and then just type 'run' in the debugger to perform the command through the debugger. If a test case causes a core dump, analyze it by running gdb like: # gdb ../curl/src core ... and get a stack trace with the gdb command: (gdb) where Logs: All logs are generated in the logs/ subdirectory (it is emptied first in the runtests.pl script). Use runtests.pl -k to keep the temporary files after the test run. Data: All test cases are put in the data/ subdirectory. Each test is stored in the file named according to the test number. See FILEFORMAT for the description of the test case files. Code coverage: gcc provides a tool that can determine the code coverage figures for the test suite. To use it, configure curl with CFLAGS='-fprofile-arcs -ftest-coverage -g -O0'. Make sure you run the normal and torture tests to get more full coverage, i.e. do: make test make test-torture The graphical tool ggcov can be used to browse the source and create coverage reports on *NIX hosts: ggcov -r lib src The text mode tool gcov may also be used, but it doesn't handle object files in more than one directory very well. Remote testing: The runtests.pl script provides some hooks to allow curl to be tested on a machine where perl can not be run. The test framework in this case runs on a workstation where perl is available, while curl itself is run on a remote system using ssh or some other remote execution method. See the comments at the beginning of runtests.pl for details. TEST CASE NUMBERS So far, I've used this system: 1 - 99 HTTP 100 - 199 FTP* 200 - 299 FILE* 300 - 399 HTTPS 400 - 499 FTPS 500 - 599 libcurl source code tests, not using the curl command tool 600 - 699 SCP/SFTP 700 - 799 SOCKS4 (even numbers) and SOCK5 (odd numbers) 1000 - 1999 miscellaneous* 2000 - x multiple sequential protocols per test case* Since 30-apr-2003, there's nothing in the system that requires us to keep within these number series, and those sections marked with * actually contain tests for a variety of protocols. Each test case now specifies its own server requirements, independent of test number. TODO: * Add tests for TELNET, LDAP, DICT... * SOCKS4/5 test deficiencies - no proxy authentication tests as SSH (the test mechanism) doesn't support them
