NAME

6       Test::Requires::Git - Check your test requirements against the
7       available version of Git
8

SYNOPSIS

10           # will skip all if git is not available
11           use Test::Requires::Git;
12
13           # needs some git that supports `git init $dir`
14           test_requires_git version_ge => '1.6.5';
15

DESCRIPTION

17       Test::Requires::Git checks if the version of Git available for testing
18       meets the given requirements. If the checks fail, then all tests will
19       be skipped.
20
21       "use Test::Requires::Git" always calls "test_requires_git" with the
22       given arguments. If you don't want "test_requires_git" to be called at
23       import time, write this instead:
24
25           use Test::Requires::Git -nocheck;
26
27       Passing the "git" parameter (see "test_requires_git" below) to "use
28       Test::Requires::Git" will override it for the rest of the program run.

EXPORTED FUNCTIONS

31   test_requires_git
32           # skip all unless git is available as required
33           test_requires_git version_ge => '1.6.5';
34
35           # giving no operator implies 'version_ge'
36           test_requires_git '1.6.5';
37
38           # skip 2 if git is not available
39         SKIP: {
40               test_requires_git skip => 2;
41               ...;
42           }
43
44           # skip 2 unless git is available as required
45         SKIP: {
46               test_requires_git
47                 skip       => 2,
48                 version_ge => '1.7.12';
49               ...;
50           }
51
52           # skip all remaining tests if git is not available
53           test_requires_git;
54
55           # force which git binary to use
56           test_requires_git
57             git        => '/usr/local/bin/git',
58             version_ge => '1.6.5';
59
60       Takes a list of version requirements (see "GIT VERSION CHECKING"
61       below), and if one of them does not pass, skips all remaining tests.
62       All conditions must be satisfied for the check to pass.
63
64       When the "skip" parameter is given, only the specified number of tests
65       will be skipped.
66
67       The "current git" is obtained by running "git --version".  I.e. the
68       first "git" binary found in the current environment will be tested.
69       This is of course sensitive to local changes to "PATH", so this will
70       behave as expected:
71
72           # skip 4 tests if there's no git available in the alternative PATH
73         SKIP: {
74               local $ENV{PATH} = $alternative_PATH;
75               test_requires_git skip => 4;
76               ...;
77           }
78
79       When the "git" parameter is given, "test_requires_git" will run that
80       program instead of "git".
81
82       If no condition is given, "test_requires_git" will simply check if
83       "git" is available.
84
85       The first time it's called, "test_require_git" will print a test
86       diagnostic with the output of "git --version" (if "git" is available,
87       of course).  To prevent this behaviour, load the module with:
88
89           use Test::Requires::Git -quiet;
90

GIT VERSION CHECKING

92       The actual comparison is handled by Git::Version::Compare, so the
93       strings can be version numbers, tags from "git.git" or the output of
94       "git version" or "git describe".
95
96       The following version checks are currently supported:
97
98   version_eq
99       Aliases: "version_eq", "eq", "==", "version".
100
101           test_requires_git version_eq => $version;
102
103       Passes if the current git version is equal to $version.
104
105   version_ne
106       Aliases: "version_ne", "ne", "!=".
107
108           test_requires_git version_eq => $version;
109
110       Passes if the current git version is not equal to $version.
111
112   version_lt
113       Aliases: "version_lt", "lt", "<".
114
115           test_requires_git version_lt => $version;
116
117       Passes if the current git version is less than $version.
118
119   version_gt
120       Aliases: "version_gt", "gt", ">".
121
122           test_requires_git version_gt => $version;
123
124       Passes if the current git version is greater than $version.
125
126   version_le
127       Aliases: "version_le", "le", "<=".
128
129           test_requires_git version_le => $version;
130
131       Passes if the current git version is less than or equal $version.
132
133   version_ge
134       Aliases: "version_ge", "ge", ">=".
135
136           test_requires_git version_ge => $version;
137
138       Passes if the current git version is greater than or equal  $version.
139
140       As a special shortcut for the most common case, a lone version number
141       is turned into a "version_ge" check, so the following two lines are
142       exactly equivalent:
143
144           test_requires_git version_ge => '1.6.5';
145
146           # version_ge implied
147           test_requires_git '1.6.5';
148

ACKNOWLEDGEMENTS

153       Thanks to Oliver Mengué (DOLMEN), who gave me the idea for this module
154       at the Perl QA Hackathon 2015 in Berlin, and suggested to give a look
155       at Test::Requires for inspiration.
