... to make all libcurl internals able to use the same data types for the struct members. The timeval struct differs subtly on several platforms so it makes it cumbersome to use everywhere. Ref: #1652 Closes #1693 |

Running 1.1 Requires to run perl (and a unix-style shell) python (and a unix-style shell) diff (when a test fails, a diff is shown) stunnel (for HTTPS and FTPS tests) OpenSSH or SunSSH (for SCP, SFTP and SOCKS4/5 tests) nghttpx (for HTTP/2 tests) nroff (for --manual tests) 1.2 Port numbers used by test servers - TCP/8990 for HTTP - TCP/8991 for HTTPS - TCP/8992 for FTP - TCP/8993 for FTPS - TCP/8994 for HTTP IPv6 - TCP/8995 for FTP (2) - TCP/8996 for FTP IPv6 - UDP/8997 for TFTP - UDP/8998 for TFTP IPv6 - TCP/8999 for SCP/SFTP - TCP/9000 for SOCKS - TCP/9001 for POP3 - TCP/9002 for POP3 IPv6 - TCP/9003 for IMAP - TCP/9004 for IMAP IPv6 - TCP/9005 for SMTP - TCP/9006 for SMTP IPv6 - TCP/9007 for RTSP - TCP/9008 for RTSP IPv6 - TCP/9009 for GOPHER - TCP/9010 for GOPHER IPv6 - TCP/9011 for HTTPS server with TLS-SRP support - TCP/9012 for HTTPS IPv6 server with TLS-SRP support - TCP/9013 for HTTP proxy server for CONNECT - TCP/9014 for HTTP pipelining server - TCP/9015 for HTTP/2 server - TCP/9016 for DICT server - TCP/9017 for SMB server - TCP/9018 for SMBS server (reserved) - TCP/9019 for TELNET server with negotiation support 1.3 Test servers The test suite runs simple FTP, POP3, IMAP, SMTP, HTTP and TFTP stand-alone servers on the ports listed above to which it makes requests. 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 (8990), which all the individual port numbers are indexed from, can be set explicitly using runtests.pl' -b option to allow running more than one instance of the test suite simultaneously on one machine, or just move the servers in case you have local services on any of those ports. The HTTP server supports listening on a Unix domain socket, the default location is 'http.sock'. 1.4 Run './configure && make && 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 aborting 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 files data/DISABLED or data/DISABLED.local (one per line). The latter is meant for local temporary disables and will be ignored by git. When -s is not present, each successful test will display on one line the test number and description and on the next line a set of flags, the test result, current test sequence, total number of tests to be run and an estimated amount of time to complete the test run. The flags consist of these letters describing what is checked in this test: s stdout d data u upload p protocol o output e exit code m memory v valgrind 1.5 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. 1.6 Memory test 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.pl' script to analyze the memory debugging output. Also, if you run tests on a machine where valgrind is found, the script will use valgrind to run the test with (unless you use -n) to further verify correctness. runtests.pl's -t option will enable torture testing mode, which runs each test many times and makes each different memory allocation 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. It can help to compile curl with CPPFLAGS=-DMEMDEBUG_LOG_SYNC when using this option, to ensure that the memory log file is properly written even if curl crashes. 1.7 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. 1.8 Logs All logs are generated in the log/ subdirectory (it is emptied first in the runtests.pl script). Use runtests.pl -k to force it to keep the temporary files after the test run since successful runs will clean it up otherwise. 1.9 Test input files 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. 1.10 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. 1.11 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. 2. Numbering 2.1 Test case numbering 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) 800 - 849 IMAP 850 - 899 POP3 900 - 999 SMTP 1000 - 1299 miscellaneous 1300 - 1399 unit tests 1400 - 1499 miscellaneous 1500 - 1599 libcurl source code tests, not using the curl command tool (same as 5xx) 1600 - 1699 unit tests 2000 - x multiple sequential protocols per test case There's nothing in the system that *requires* us to keep within these number series. 3. Write tests Here's a quick description on writing test cases. We basically have three kinds of tests: the ones that test the curl tool, the ones that build small applications and test libcurl directly and the unit tests that test individual (possibly internal) functions. 3.1 test data Each test has a master file that controls all the test data. What to read, what the protocol exchange should look like, what exit code to expect and what command line arguments to use etc. These files are tests/data/test[num] where [num] is described in section 2 of this document, and the XML-like file format of them is described in the separate tests/FILEFORMAT document. 3.2 curl tests A test case that runs the curl tool and verifies that it gets the correct data, it sends the correct data, it uses the correct protocol primitives etc. 3.3 libcurl tests The libcurl tests are identical to the curl ones, except that they use a specific and dedicated custom-built program to run instead of "curl". This tool is built from source code placed in tests/libtest and if you want to make a new libcurl test that is where you add your code. 3.4 unit tests Unit tests are tests in the 13xx sequence and they are placed in tests/unit. There's a tests/unit/README describing the specific set of checks and macros that may be used when writing tests that verify behaviors of specific individual functions. The unit tests depend on curl being built with debug enabled. 4. TODO 4.1 More protocols Add tests for TELNET, LDAP, DICT... 4.2 SOCKS auth SOCKS4/5 test deficiencies - no proxy authentication tests as SSH (the test mechanism) doesn't support them
