=head1 NAME

selftest - Samba test runner

=head1 SYNOPSIS

selftest --help

selftest [--srcdir=DIR] [--builddir=DIR] [--exeext=EXT][--target=samba4|samba3|win|kvm] [--socket-wrapper] [--quick] [--exclude=FILE] [--include=FILE] [--one] [--prefix=prefix] [--testlist=FILE] [TESTS]

=head1 DESCRIPTION

A simple test runner. TESTS is a regular expression with tests to run.

=head1 OPTIONS

=over 4

=item I<--help>

Show list of available options.

=item I<--srcdir=DIR>

Source directory.

=item I<--builddir=DIR>

Build directory.

=item I<--exeext=EXT>

Executable extention

=item I<--prefix=DIR>

Change directory to run tests in. Default is 'st'.

=item I<--target samba4|samba3|win|kvm>

Specify test target against which to run. Default is 'samba4'.

=item I<--quick>

Run only a limited number of tests. Intended to run in about 30 seconds on 
moderately recent systems.
		
=item I<--socket-wrapper>

Use socket wrapper library for communication with server. Only works 
when the server is running locally.

Will prevent TCP and UDP ports being opened on the local host but 
(transparently) redirects these calls to use unix domain sockets.

=item I<--exclude>

Specify a file containing a list of tests that should be skipped. Possible 
candidates are tests that segfault the server, flip or don't end. 

=item I<--include>

Specify a file containing a list of tests that should be run. Same format 
as the --exclude flag.

Not includes specified means all tests will be run.

=item I<--one>

Abort as soon as one test fails.

=item I<--testlist>

Load a list of tests from the specified location.

Usage: $Script [OPTIONS] TESTNAME-REGEX

Generic options:
 --help                     this help page
 --target=samba[34]|win|kvm Samba version to target
 --testlist=FILE	    file to read available tests from

Paths:
 --prefix=DIR               prefix to run tests in [st]
 --srcdir=DIR               source directory [.]
 --builddir=DIR             output directory [.]
 --exeext=EXT               executable extention []

Target Specific:
 --socket-wrapper-pcap	    save traffic to pcap directories
 --socket-wrapper-keep-pcap keep all pcap files, not just those for tests that 
                            failed
 --socket-wrapper           enable socket wrapper
 --bindir=PATH              path to target binaries

Samba4 Specific:
 --ldap=openldap|fedora-ds  back samba onto specified ldap server

Kvm Specific:
 --image=PATH               path to KVM image

Behaviour:
 --quick                    run quick overall test
 --one                      abort when the first test fails
 --verbose                  be verbose
 --analyse-cmd CMD          command to run after each test
";
