.TH runtests.pl 1 "11 Oct 2007" "Curl 7.17.1" "runtests"
.SH NAME
runtests.pl \- run one or more test cases
.SH SYNOPSIS
.B runtests.pl [options] [test number]
.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".
.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 "-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.

The test script checks this by itself, why it is safe to attempt to run all
tests. They who cannot be run due to failed requirements, will simply be
skipped and you'll get a report about it when all test cases have completed.
.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.
Something went wrong with that request. Please try again.
