- .TH runtests.pl 1 "2 Feb 2010" "Curl 7.20.0" "runtests"
- .SH NAME
- runtests.pl \- run one or more test cases
- .SH SYNOPSIS
- .B runtests.pl [options] [test number] [!test number] [key word] [!key word]
- .SH DESCRIPTION
- \fIruntests.pl\fP runs one, several or all the existing test cases in curl's
- test suite. It is often called from the root Makefile of the curl package with
- \&'make test'.
- .SH "TEST NUMBER"
- If no test case number is given, all existing tests that the script can find
- will be considered for running. You can specify single test cases to run,
- space-separated, like "1 3 5 7 11", and you can specify a range like "45 to
- 67". You can also specify only the tests you don't want to run by listing
- the numbers with a leading exclamation point, like "!66".
- .P
- It is also possible to specify tests to skip based on a key word describing
- the test. These are specified with a leading exclamation point and the
- key word or phrase, like "!HTTP NTLM auth". Likewise, tests to run can
- be specified simply by specifying the unadorned key words, like "FTPS".
- Remember that the exclamation marks and spaces will need to be quoted somehow
- when entered at many command shells.
- .SH OPTIONS
- .IP "-a"
- Continue running the rest of the test cases even if one test fails. By
- default, the test script stops as soon as an error is detected.
- .IP "-bN"
- Use N as the base TCP/UDP port number on which to start the test servers.
- .IP "-c <curl>"
- Provide a custom curl binary to run the tests with. Default is the curl
- executable in the build tree.
- .IP "-d"
- Enable protocol debug: have the servers display protocol output.
- .IP "-g"
- Run the given test(s) with gdb. This is best used on a single test case and
- curl built --disable-shared. This then fires up gdb with command line set to
- run the specified test case. Simply (set a break-point and) type 'run' to
- start.
- .IP "-h"
- Displays a help text about this program's command line options.
- .IP "-k"
- Keep output and log files in log/ after a test run, even if no error was
- detected. Useful for debugging.
- .IP "-l"
- Lists all test case names.
- .IP "-n"
- Disable the check for and use of valgrind.
- .IP "-p"
- Prints out all files in "log/" to stdout when a test case fails. Very
- practical when used in the automated and distributed tests since then the
- people checking the failures and the reasons for them might not have physical
- access to the machine and logs.
- .IP "-r"
- Display run time statistics. (Requires Perl Time::HiRes module)
- .IP "-rf"
- Display full run time statistics. (Requires Perl Time::HiRes module)
- .IP "-s"
- Shorter output. Speaks less than default.
- .IP "-t[num]"
- Selects a \fBtorture\fP test for the given tests. This makes runtests.pl first
- run the tests once and count the number of memory allocations made. It then
- reruns the test that number of times, each time forcing one of the allocations
- to fail until all allocs have been tested. By setting \fInum\fP you can force
- the allocation with that number to be set to fail at once instead of looping
- through everyone, which is very handy when debugging and then often in
- combination with \fI-g\fP.
- .IP "-v"
- Enable verbose output. Speaks more than default.
- .SH "RUNNING TESTS"
- Many tests have conditions that must be met before the test case can run
- fine. They could depend on built-in features in libcurl or features present in
- the operating system or even in third-party libraries that curl may or may not
- use.
- .P
- The test script checks most of these by itself to determine when it is
- safe to attempt to run each test. Those which cannot be run due to
- failed requirements will simply be skipped and listed at the completion
- of all test cases. In some unusual configurations, the test script
- cannot make the correct determination for all tests. In these cases,
- the problematic tests can be skipped using the "!keyword" skip feature
- documented earlier.
- .SH "WRITING TESTS"
- The simplest way to write test cases is to start with a similar existing test,
- save it with a new number and then adjust it to fit. There's an attempt to
- document the test case file format in the tests/FILEFORMAT.
