12 Instead of this:
13
14 use strict;
15 use warnings;
16 use Test::Exception 0.88;
17 use Test::Differences 0.500;
18 use Test::Deep 0.106;
19 use Test::Warn 0.11;
20 use Test::More 0.88;
21
22 use parent 'My::Test::Class';
23
24 sub some_test : Tests { ... }
25
26 You type this:
27
28 use Test::Class::Most parent => 'My::Test::Class';
29
30 sub some_test : Tests { ... }
31
33 When people write test classes with the excellent "Test::Class", you
34 often see the following at the top of the code:
35
36 package Some::Test::Class;
37
38 use strict;
39 use warnings;
40 use base 'My::Test::Class';
41 use Test::More;
42 use Test::Exception;
43
44 # and then the tests ...
45
46 That's a lot of boilerplate and I don't like boilerplate. So now you
47 can do this:
48
49 use Test::Class::Most parent => 'My::Test::Class';
50
51 That automatically imports strict and warnings for you. It also gives
52 you all of the testing goodness from Test::Most.
53
55 You probably want to create your own base class for testing. To do
56 this, simply specify no import list:
57
58 package My::Test::Class;
59 use Test::Class::Most; # we now inherit from Test::Class
60
61 INIT { Test::Class->runtests }
62
63 1;
64
65 And then your other classes inherit as normal (well, the way we do it):
66
67 package Tests::For::Foo;
68 use Test::Class::Most parent => 'My::Test::Class';
69
70 And you can inherit from those other classes, too:
71
72 package Tests::For::Foo::Child;
73 use Test::Class::Most parent => 'Tests::For::Foo';
74
75 Of course, it's quite possible that you're a fan of multiple
76 inheritance, so you can do that, too (I was soooooo tempted to not
77 allow this, but I figured I shouldn't force too many of my personal
78 beliefs on you):
79
80 package Tests::For::ISuckAtOO;
81 use Test::Class::Most parent => [qw/
82 Tests::For::Foo
83 Tests::For::Bar
84 Some::Other::Class::For::Increased::Stupidity
85 /];
86
87 As a side note, it's recommended that even if you don't need test
88 control methods in your base class, put stubs in there:
89
90 package My::Test::Class;
91 use Test::Class::Most; # we now inherit from Test::Class
92
93 INIT { Test::Class->runtests }
94
95 sub startup : Tests(startup) {}
96 sub setup : Tests(setup) {}
97 sub teardown : Tests(teardown) {}
98 sub shutdown : Tests(shutdown) {}
99
100 1;
101
102 This allows developers to always be able to safely call parent test
103 control methods rather than wonder if they are there:
104
105 package Tests::For::Customer;
106 use Test::Class::Most parent => 'My::Test::Class';
107
108 sub setup : Tests(setup) {
109 my $test = shift;
110 $test->next::method; # safe due to stub in base class
111 ...
112 }
113
115 You can also specify "attributes" which are merely very simple
116 getter/setters.
117
118 use Test::Class::Most
119 parent => 'My::Test::Class',
120 attributes => [qw/customer items/],
121 is_abstract => 1;
122
123 sub setup : Tests(setup) {
124 my $test = shift;
125 $test->SUPER::setup;
126 $test->customer( ... );
127 $test->items( ... );
128 }
129
130 sub some_tests : Tests {
131 my $test = shift;
132 my $customer = $test->customer;
133 ...
134 }
135
136 If called with no arguments, returns the current value. If called with
137 one argument, sets that argument as the current value. If called with
138 more than one argument, it croaks.
139
141 You may pass an optional "is_abstract" parameter in the import list. It
142 takes a boolean value. This value is advisory only and is not
143 inherited. It defaults to false if not provided.
144
145 Sometimes you want to identify a test class as "abstract". It may have
146 a bunch of tests, but those should only run for its subclasses. You can
147 pass "<is_abstract =" 1>> in the import list. Then, to test if a given
148 class or instance of that class is "abstract":
149
150 sub dont_run_in_abstract_base_class : Tests {
151 my $test = shift;
152 return if Test::Class::Most->is_abstract($test);
153 ...
154 }
155
156 Note that "is_abstract" is strictly advisory only. You are expected
157 (required) to check the value yourself and take appropriate action.
158
159 We recommend adding the following method to your base class:
160
161 sub is_abstract {
162 my $test = shift;
163 return Test::Class::Most->is_abstract($test);
164 }
165
166 And later in a subclass:
167
168 if ( $test->is_abstract ) { ... }
169
171 All functions from Test::Most are automatically exported into your
172 namespace.
