The cURL Test Suite

  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.

  '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

  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.

  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

  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

  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.

  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.


 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.


  * Add tests for TELNET, LDAP, DICT...
  * SOCKS4/5 test deficiencies - no proxy authentication tests as SSH (the
    test mechanism) doesn't support them
