#!/usr/bin/perl # Bootstrap Samba and run a number of tests against it. # Copyright (C) 2005-2008 Jelmer Vernooij # Published under the GNU GPL, v3 or later. =pod =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] [--immediate] [--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<--immediate> Show errors as soon as they happen rather than at the end of the test run. =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<--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 The reason for a test can also be specified, by adding a hash sign (#) and the reason after the test name. =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. The format of this file is the same as for the --expected-failures flag. =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. =back =head1 ENVIRONMENT =over 4 =item I =item I =item I =item I =item I =back =head1 LICENSE selftest is licensed under the GNU General Public License L. =head1 AUTHOR Jelmer Vernooij =cut use strict; use FindBin qw($RealBin $Script); use File::Spec; use Getopt::Long; use POSIX; use Cwd qw(abs_path); use lib "$RealBin"; use Subunit qw(parse_results); use SocketWrapper; my $opt_help = 0; my $opt_target = "samba4"; my $opt_quick = 0; my $opt_socket_wrapper = 0; my $opt_socket_wrapper_pcap = undef; my $opt_socket_wrapper_keep_pcap = undef; my $opt_one = 0; my $opt_immediate = 0; my $opt_expected_failures = undef; my @opt_exclude = (); my @opt_include = (); my $opt_verbose = 0; my $opt_image = undef; my $opt_testenv = 0; my $ldap = undef; my $opt_analyse_cmd = undef; my $opt_resetup_env = undef; my $opt_bindir = undef; my $opt_no_lazy_setup = undef; my $opt_format = "plain"; my @testlists = (); my $srcdir = "."; my $builddir = "."; my $exeext = ""; my $prefix = "./st"; my @expected_failures = (); my @includes = (); my @excludes = (); my $statistics = { SUITES_FAIL => 0, TESTS_UNEXPECTED_OK => 0, TESTS_EXPECTED_OK => 0, TESTS_UNEXPECTED_FAIL => 0, TESTS_EXPECTED_FAIL => 0, TESTS_ERROR => 0, TESTS_SKIP => 0, }; sub find_in_list($$) { my ($list, $fullname) = @_; foreach (@$list) { if ($fullname =~ /$$_[0]/) { return ($$_[1]) if ($$_[1]); return "NO REASON SPECIFIED"; } } return undef; } sub expecting_failure($) { my ($name) = @_; return find_in_list(\@expected_failures, $name); } sub skip($) { my ($name) = @_; return find_in_list(\@excludes, $name); } sub getlog_env($); sub setup_pcap($) { my ($name) = @_; return unless ($opt_socket_wrapper_pcap); return unless defined($ENV{SOCKET_WRAPPER_PCAP_DIR}); my $fname = $name; $fname =~ s%[^abcdefghijklmnopqrstuvwxyzABCDEFGHIJKLMNOPQRSTUVWXYZ0123456789\-]%_%g; my $pcap_file = "$ENV{SOCKET_WRAPPER_PCAP_DIR}/$fname.pcap"; SocketWrapper::setup_pcap($pcap_file); return $pcap_file; } sub cleanup_pcap($$$) { my ($pcap_file, $expected_ret, $ret) = @_; return unless ($opt_socket_wrapper_pcap); return if ($opt_socket_wrapper_keep_pcap); return unless ($expected_ret == $ret); return unless defined($pcap_file); unlink($pcap_file); } sub run_testsuite($$$$$$) { my ($envname, $name, $cmd, $i, $totalsuites, $msg_ops) = @_; my $pcap_file = setup_pcap($name); $msg_ops->start_test([], $name); unless (open(RESULT, "$cmd 2>&1|")) { $statistics->{TESTS_ERROR}++; $msg_ops->end_test([], $name, "error", 1, "Unable to run $cmd: $!"); $statistics->{SUITES_FAIL}++; return 0; } my $expected_ret = parse_results( $msg_ops, $statistics, *RESULT, \&expecting_failure, [$name]); my $envlog = getlog_env($envname); $msg_ops->output_msg("ENVLOG: $envlog\n") if ($envlog ne ""); $msg_ops->output_msg("CMD: $cmd\n"); my $ret = close(RESULT); $ret = 0 unless $ret == 1; my $exitcode = $?
