The cURL Test Suite
|
|
|
|
Requires:
|
|
perl (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)
|
|
|
|
Ports used by default:
|
|
|
|
- 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 IMAP
|
|
- TCP/9003 for SMTP
|
|
|
|
The test suite runs simple FTP, POP3, IMAP, SMTP, HTTP and TFTP stand-alone
|
|
servers on these ports 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 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, we'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)
|
|
800 - 899 POP3, IMAP, SMTP
|
|
1000 - 1299 miscellaneous*
|
|
1300 - 1399 unit tests*
|
|
1400 - 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
|
