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


    # will skip all if git is not available
    use Test::Requires::Git;

    # needs some git that supports `git init $dir`
    test_requires_git version_ge => '1.6.5';


Test::Requires::Git checks if the version of Git available for testing meets the given requirements. If the checks fail, then all tests will be skipped.

use Test::Requires::Git always calls test_requires_git with the given arguments. If you don't want test_requires_git to be called at import time, write this instead:

    use Test::Requires::Git -nocheck;

Passing the git parameter (see "test_requires_git" below) to use Test::Requires::Git will override it for the rest of the program run.



    # skip all unless git is available as required
    test_requires_git version_ge => '1.6.5';

    # giving no operator implies 'version_ge'
    test_requires_git '1.6.5';

    # skip 2 if git is not available
  SKIP: {
        test_requires_git skip => 2;

    # skip 2 unless git is available as required
  SKIP: {
          skip       => 2,
          version_ge => '1.7.12';

    # skip all remaining tests if git is not available

    # force which git binary to use
      git        => '/usr/local/bin/git',
      version_ge => '1.6.5';

Takes a list of version requirements (see "GIT VERSION CHECKING" below), and if one of them does not pass, skips all remaining tests. All conditions must be satisfied for the check to pass.

When the skip parameter is given, only the specified number of tests will be skipped.

The "current git" is obtained by running git --version. I.e. the first git binary found in the current environment will be tested. This is of course sensitive to local changes to PATH, so this will behave as expected:

    # skip 4 tests if there's no git available in the alternative PATH
  SKIP: {
        local $ENV{PATH} = $alternative_PATH;
        test_requires_git skip => 4;

When the git parameter is given, test_requires_git will run that program instead of git.

If no condition is given, test_requires_git will simply check if git is available.

The first time it's called, test_require_git will print a test diagnostic with the output of git --version (if git is available, of course). To prevent this behaviour, load the module with:

    use Test::Requires::Git -quiet;


The actual comparison is handled by Git::Version::Compare, so the strings can be version numbers, tags from git.git or the output of git version or git describe.

The following version checks are currently supported:


Aliases: version_eq, eq, ==, version.

    test_requires_git version_eq => $version;

Passes if the current git version is equal to $version.


Aliases: version_ne, ne, !=.

    test_requires_git version_eq => $version;

Passes if the current git version is not equal to $version.


Aliases: version_lt, lt, <.

    test_requires_git version_lt => $version;

Passes if the current git version is less than $version.


Aliases: version_gt, gt, >.

    test_requires_git version_gt => $version;

Passes if the current git version is greater than $version.


Aliases: version_le, le, <=.

    test_requires_git version_le => $version;

Passes if the current git version is less than or equal $version.


Aliases: version_ge, ge, >=.

    test_requires_git version_ge => $version;

Passes if the current git version is greater than or equal $version.

As a special shortcut for the most common case, a lone version number is turned into a version_ge check, so the following two lines are exactly equivalent:

    test_requires_git version_ge => '1.6.5';

    # version_ge implied
    test_requires_git '1.6.5';


Test::Requires, Git::Version::Compare.


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