6 App::Prove - Implements the "prove" command.
7
9 Version 3.48
10
12 Test::Harness provides a command, "prove", which runs a TAP based test
13 suite and prints a report. The "prove" command is a minimal wrapper
14 around an instance of this module.
15
17 use App::Prove;
18
19 my $app = App::Prove->new;
20 $app->process_args(@ARGV);
21 $app->run;
22
24 Class Methods
25 "new"
26
27 Create a new "App::Prove". Optionally a hash ref of attribute
28 initializers may be passed.
29
30 "state_class"
31
32 Getter/setter for the name of the class used for maintaining state.
33 This class should either subclass from "App::Prove::State" or provide
34 an identical interface.
35
36 "state_manager"
37
38 Getter/setter for the instance of the "state_class".
39
40 "add_rc_file"
41
42 $prove->add_rc_file('myproj/.proverc');
43
44 Called before "process_args" to prepend the contents of an rc file to
45 the options.
46
47 "process_args"
48
49 $prove->process_args(@args);
50
51 Processes the command-line arguments. Attributes will be set
52 appropriately. Any filenames may be found in the "argv" attribute.
53
54 Dies on invalid arguments.
55
56 "run"
57
58 Perform whatever actions the command line args specified. The "prove"
59 command line tool consists of the following code:
60
61 use App::Prove;
62
63 my $app = App::Prove->new;
64 $app->process_args(@ARGV);
65 exit( $app->run ? 0 : 1 ); # if you need the exit code
66
67 "require_harness"
68
69 Load a harness replacement class.
70
71 $prove->require_harness($for => $class_name);
72
73 "print_version"
74
75 Display the version numbers of the loaded TAP::Harness and the current
76 Perl.
77
78 Attributes
79 After command line parsing the following attributes reflect the values
80 of the corresponding command line switches. They may be altered before
81 calling "run".

126 "App::Prove" provides support for 3rd-party plugins. These are
127 currently loaded at run-time, after arguments have been parsed (so you
128 can not change the way arguments are processed, sorry), typically with
129 the "-Pplugin" switch, eg:
130
131 prove -PMyPlugin
132
133 This will search for a module named "App::Prove::Plugin::MyPlugin", or
134 failing that, "MyPlugin". If the plugin can't be found, "prove" will
135 complain & exit.
136
137 You can pass an argument to your plugin by appending an "=" after the
138 plugin name, eg "-PMyPlugin=foo". You can pass multiple arguments
139 using commas:
140
141 prove -PMyPlugin=foo,bar,baz
142
143 These are passed in to your plugin's load() class method (if it has
144 one), along with a reference to the "App::Prove" object that is
145 invoking your plugin:
146
147 sub load {
148 my ($class, $p) = @_;
149
150 my @args = @{ $p->{args} };
151 # @args will contain ( 'foo', 'bar', 'baz' )
152 $p->{app_prove}->do_something;
153 ...
154 }
155
156 Sample Plugin
157 Here's a sample plugin, for your reference:
158
159 package App::Prove::Plugin::Foo;
160
161 # Sample plugin, try running with:
162 # prove -PFoo=bar -r -j3
163 # prove -PFoo -Q
164 # prove -PFoo=bar,My::Formatter
165
166 use strict;
167 use warnings;
168
169 sub load {
170 my ($class, $p) = @_;
171 my @args = @{ $p->{args} };
172 my $app = $p->{app_prove};
173
174 print "loading plugin: $class, args: ", join(', ', @args ), "\n";
175
176 # turn on verbosity
177 $app->verbose( 1 );
178
179 # set the formatter?
180 $app->formatter( $args[1] ) if @args > 1;
181
182 # print some of App::Prove's state:
183 for my $attr (qw( jobs quiet really_quiet recurse verbose )) {
184 my $val = $app->$attr;
185 $val = 'undef' unless defined( $val );
186 print "$attr: $val\n";
187 }
188
189 return 1;
190 }
191
192 1;
