From 88b08b5835f4ef2bae3218fe0fe808dc9151f424 Mon Sep 17 00:00:00 2001 From: Amitai Schlair Date: Sun, 22 Jan 2012 09:54:30 -0500 Subject: Ape xUnit more closely to remove ordering constraints on test subs: * Add setup and teardown methods, called before and after every test sub. * In setup, make a fresh repo; in teardown, throw it out. * Extract runtests method and define default test methods at top. * Move reflection routines near the xUnit-style subs they support. Adapt existing test subs to run independently: * In test_manual_add_and_commit(), assume a fresh repo. While here, plan a bit better: * Check for all modules used by cvs.pm. * Check for program existence more generally. * Check that we can rmdir after mkdir. --- t/cvs.t | 142 +++++++++++++++++++++++++++++++++++++++------------------------- 1 file changed, 86 insertions(+), 56 deletions(-) (limited to 't/cvs.t') diff --git a/t/cvs.t b/t/cvs.t index a8f1254ef..d34d40999 100755 --- a/t/cvs.t +++ b/t/cvs.t @@ -1,50 +1,105 @@ #!/usr/bin/perl use warnings; use strict; -use Test::More; my $total_tests = 10; +use Test::More; my $total_tests = 9; use IkiWiki; +my $default_test_methods = '^test_*'; my $dir = "/tmp/ikiwiki-test-cvs.$$"; -sub _plan { +sub _plan_for_test_more { my $can_plan = shift; - my $cvs = `which cvs`; chomp $cvs; - my $cvsps = `which cvsps`; chomp $cvsps; - return plan(skip_all => 'cvs or cvsps not available') - unless -x $cvs && -x $cvsps; + foreach my $program (qw( + cvs + cvsps + )) { + my $program_path = `which $program`; + chomp $program_path; + return plan(skip_all => "$program not available") + unless -x $program_path; + } - foreach my $module (qw(File::ReadBackwards File::MimeInfo)) { + foreach my $module (qw( + File::chdir + File::MimeInfo + Date::Parse + File::Temp + File::ReadBackwards + )) { eval qq{use $module}; - if ($@) { - return plan(skip_all => "$module not available"); - } + return plan(skip_all => "$module not available") + if $@; } return plan(skip_all => "can't create $dir: $!") unless mkdir($dir); + return plan(skip_all => "can't remove $dir: $!") + unless rmdir($dir); return unless $can_plan; return plan(tests => $total_tests); } + +# http://stackoverflow.com/questions/607282/whats-the-best-way-to-discover-all-subroutines-a-perl-module-has + +use B qw/svref_2object/; + +sub in_package { + my ($coderef, $package) = @_; + my $cv = svref_2object($coderef); + return if not $cv->isa('B::CV') or $cv->GV->isa('B::SPECIAL'); + return $cv->GV->STASH->NAME eq $package; +} + +sub list_module { + my $module = shift; + no strict 'refs'; + return grep { + defined &{"$module\::$_"} and in_package(\&{*$_}, $module) + } keys %{"$module\::"}; +} + + +# support for xUnit-style testing, a la Test::Class + sub _startup { my $can_plan = shift; - - _plan($can_plan); - _generate_minimal_config(); - _create_test_repo(); + _plan_for_test_more($can_plan); + _generate_test_config(); } sub _shutdown { my $had_plan = shift; + done_testing() unless $had_plan; +} + +sub _setup { + _generate_test_repo(); +} +sub _teardown { system "rm -rf $dir"; - done_testing() unless $had_plan; } -sub _generate_minimal_config { +sub _runtests { + my @coderefs = (@_); + for (@coderefs) { + _setup(); + $_->(); + _teardown(); + } +} + +sub _get_matching_test_subs { + my $re = shift; + no strict 'refs'; + return map { \&{*$_} } grep { /$re/ } list_module('main'); +} + +sub _generate_test_config { %config = IkiWiki::defaultconfig(); $config{rcs} = "cvs"; $config{srcdir} = "$dir/src"; @@ -54,7 +109,10 @@ sub _generate_minimal_config { IkiWiki::checkconfig(); } -sub _create_test_repo { +sub _generate_test_repo { + die "can't create $dir: $!" + unless mkdir($dir); + my $cvs = "cvs -d $config{cvsrepo}"; my $dn = ">/dev/null"; system "$cvs init $dn"; @@ -65,8 +123,11 @@ sub _create_test_repo { system "$cvs co -d $config{srcdir} $config{cvspath} $dn"; } + +# tests for general meta-behavior: + sub test_web_add_and_commit { - my $message = "Added the first page"; + my $message = "Add a page via VCS API"; writefile('test1.mdwn', $config{srcdir}, readfile("t/test1.mdwn")); IkiWiki::rcs_add("test1.mdwn"); IkiWiki::rcs_commit( @@ -106,7 +167,7 @@ sub test_web_add_and_commit { } sub test_manual_add_and_commit { - my $message = "Added the second page"; + my $message = "Add a page via CVS directly"; writefile('test2.mdwn', $config{srcdir}, readfile("t/test2.mdwn")); system "cd $config{srcdir}" .
