=head1 NAME

selftest - Samba test runner

=head1 SYNOPSIS

selftest --help

selftest [--srcdir=DIR] [--builddir=DIR] [--target=samba4|samba3|win] [--socket-wrapper] [--quick] [--one] [--prefix=prefix] [--immediate] [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<--prefix=DIR>

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

=item I<--immediate>

Show errors as soon as they happen rather than at the end of the test run.
		
=item I<--target samba4|samba3|win>

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<--expected-failures>

Specify a file containing a list of tests that are expected to fail. Failures for 
these tests will be counted as successes, successes will be counted as failures.

The format for the file is, one entry per line:

TESTSUITE-NAME/TEST-NAME

=item I<--skip>

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<--one>

Abort as soon as one test fails.

=back

=head1 ENVIRONMENT

=over 4

=item I<SMBD_VALGRIND>

=item I<TORTURE_MAXTIME>

=item I<VALGRIND>

=item I<TLS_ENABLED>

Usage: $Script [OPTIONS] PREFIX

Generic options:
 --help                     this help page
 --target=samba4|samba3|win Samba version to target

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

Target Specific:
 --socket-wrapper-pcap=DIR	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
 --expected-failures=FILE   specify list of tests that is guaranteed to fail

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

Samba3 Specific:
 --bindir=PATH              path to binaries

Behaviour:
 --quick                    run quick overall test
 --one                      abort when the first test fails
 --immediate                print test output for failed tests during run
 --verbose                  be verbose
 --analyse-cmd CMD          command to run after each test
