NAME

6       Test2::Manual::Testing - Hub for documentation about writing tests with
7       Test2.

DESCRIPTION

10       This document outlines all the tutorials and POD that cover writing
11       tests. This section does not cover any Test2 internals, nor does it
12       cover how to write new tools, for that see Test2::Manual::Tooling.
13

NAMESPACE MAP

15       When writing tests there are a couple namespaces to focus on:
16
17       Test2::Tools::*
18           This is where toolsets can be found. A toolset exports functions
19           that help you make assertions about your code. Toolsets will only
20           export functions, they should not ever have extra/global effects.
21
22       Test2::Plugins::*
23           This is where plugins live. Plugins should not export anything, but
24           instead will introduce or alter behaviors for Test2 in general.
25           These behaviors may be lexically scoped, or they may be global.
26
27       Test2::Bundle::*
28           Bundles combine toolsets and plugins together to reduce your
29           boilerplate. First time test writers are encouraged to start with
30           the Test2::V0 bundle (which is an exception to the namespace rule
31           as it does not live under "Test2::Bundle::"). If you find yourself
32           loading several plugins and toolsets over and over again you could
33           benefit from writing your own bundle.
34
35       Test2::Require::*
36           This namespace contains modules that will cause a test to skip if
37           specific conditions are not met. Use this if you have tests that
38           only run on specific perl versions, or require external libraries
39           that may not always be available.

LISTING DEPENDENCIES

42       When you use Test2, specifically things included in Test2::Suite you
43       need to list them in your modules test dependencies. It is important to
44       note that you should list the tools/plugins/bundles you need, you
45       should not simply list Test2::Suite as your dependency. Test2::Suite is
46       a living distribution intended to represent the "current" best
47       practices. As tools, plugins, and bundles evolve, old ones will become
48       discouraged and potentially be moved from Test2::Suite into their own
49       distributions.
50
51       One goal of Test2::Suite is to avoid breaking backwards compatibility.
52       Another goal is to always improve by replacing bad designs with better
53       ones.  When necessary Test2::Suite will break old modules out into
54       separate dists and define new ones, typically with a new bundle. In
55       short, if we feel the need to break something we will do so by creating
56       a new bundle, and discouraging the old one, but we will not break the
57       old one.
58
59       So for example, if you use Test2::V0, and Dist::Zilla you should have
60       this in your config:
61
62           [Prereqs / TestRequires]
63           Test2::V0 = 0.000060
64
65       You SHOULD NOT do this:
66
67           [Prereqs / TestRequires]
68           Test2::Suite = 0.000060
69
70       Because Test2::V0 might not always be part of Test2::Suite.
71
72       When writing new tests you should often check Test2::Suite to see what
73       the current recommended bundle is.
74
75       Dist::Zilla
76
77           [Prereqs / TestRequires]
78           Test2::V0 = 0.000060
79
80       ExtUtils::MakeMaker
81
82           my %WriteMakefileArgs = (
83             ...,
84             "TEST_REQUIRES" => {
85               "Test2::V0" => "0.000060"
86             },
87             ...
88           );
89
90       Module::Install
91
92           test_requires 'Test2::V0' => '0.000060';
93
94       Module::Build
95
96           my $build = Module::Build->new(
97               ...,
98               test_requires => {
99                   "Test2::V0" => "0.000060",
100               },
101               ...
102           );
