NAME Test::Applify - Testing Applify scripts SYNOPSIS use Test::More; use Test::Applify 'applify_ok'; my $t = Test::Applify->new('./bin/app.pl'); $t->help_ok(qr/basic/) ->documentation_ok ->version_ok('1.0.999'); $t->is_option($_) for qw{mode input}; $t->is_required_option($_) for qw{input}; my $app1 = $t->app_instance(qw{-input strings.txt}); is $app1->mode, 'basic', 'basic mode is default'; my $app2 = $t->app_instance(qw{-mode expert -input strings.txt}); is $app2->mode, 'expert', 'expert mode enabled'; is $app2->input, 'strings.txt', 'reading strings.txt'; $t->run_instance_ok($app2); my $inlineapp = applify_ok("use Applify; app { print 'hello world!'; 0;};"); $t = Test::Applify->new($inlineapp); DESCRIPTION Test::Applify is a test agent to be used with Test::More to test Applify scripts. To run your tests use prove. $ prove -l -v t Avoid testing the Applify code for correctness, it has its own test suite. Instead, test for consistency of option behaviour, defaults and requiredness, the script is compiled and that attributes and methods of the script behave with different inputs. The aim is to remove repetition of multiple blocks to retrieve instances and checks for success of "do". my $app = do 'bin/app.pl'; ## check $@ and return value { local @ARGV = qw{...}; my $instance = $app->_script->app; # more tests. } EXPORTED FUNCTIONS applify_ok use Test::Applify 'applify_ok'; my $inlineapp = applify_ok("use Applify; app { print 'Hello world!'; 0;};"); my $t = Test::Applify->new($inlineapp); my $helloapp = applify_ok("use Applify; app { print 'Hello $_[1]!'; 0;};", \@ARGV, 'hello app'); my $t = Test::Applify->new($helloapp); Utility function that wraps "eval" in perlfunc and runs the same tests as "new". This function must be imported. applify_subcommands_ok use Test::Applify 'applify_subcommands_ok'; my $subcmds = applify_subcommands_ok($code); foreach my $app(@$subcmds){ Test::Applify->new($app)->help_ok ->documentation_ok ->version_ok('1') ->is_required_option('global_option') } Like "applify_ok", but creates each of the subcommands and return in an array reference. METHODS app my $t = Test::Applify->new('./bin/app.pl'); my $app = $t->app; Access to the application. N.B. The removal of "." from @INC requires relative paths to start with "./". See link for further information app_script my $script = $t->app_script; isa_ok $script, 'Applify', 'the Applify object'; Access to the Applify object. app_instance my $safe = $t->app_instance(qw{-opt value -mode safe}); is $safe->mode, 'safe', 'will run in safe mode'; my $risky = $t->app_instance(); is $risky->mode, 'expert', 'expert mode is the default'; Create an instance of the application class, which will be the contents of the Applify script created. The array passed will be turned into @ARGV as if those options had been passed on the command line. can_ok $t->can_ok(qw{mode input}); Test for the presence of methods that the script has. documentation_ok $t->documentation_ok; Test the documentation. extends_ok $t->extends_ok('Parent::Class'); $t->extends_ok('Parent::Class', 'object name'); Test the inheritance. help_ok my $help = $t->help_ok; Test and access the help for the script. is_option $t->is_option('mode'); $t->is_option($_) for qw{mode input}; Test for the presence of an option with the supplied name is_required_option $t->is_required_option('input'); Test that the option is a required option. new my $t = Test::Applify->new('./script.pl'); # instance for the 'list' subcommand my $t = Test::Applify->new('./script.pl', 'list'); Instantiate a new test instance for the supplied script name. run_instance_ok my $t = Test::Applify->new('./script.pl'); my $app = $t->app_instance(qw{-mode expert}); is $app->mode, 'expert', 'everyone is an expert'; my ($retval, $stdout, $stderr, $exited) = $t->run_instance_ok($app); Call "run" on the Applify application class instance (execute the "app {}" block). Returns a list of scalars which are: retval - the return value of the "app" block This is "undef" when "die" in perlfunc called stdout - the content that was printed to "STDOUT" during the run stderr - "$@" in perlvar or the content that was printed to "STDERR" during the run exit - whether the code exited run_ok my $t = Test::Applify->new('./script.pl'); my ($exit, $stdout, $stderr, $retval) = $t->run_ok(qw{-mode expert}); Same as "run_instance_ok", but less code. subcommand_ok my $subcommand = $t->subcommand_ok('list'); Test that the subcommand computed from @ARGV matches the supplied subcommand. version_ok $t->version_ok('1.0.999'); Test that the version matches the supplied version.
