NAME

Test::Git - Helper functions for test scripts using Git

SYNOPSIS

    use Test::More;
    use Test::Git;
    
    # check there is a git binary available, or skip all
    has_git();
    
    # check there is a minimum version of git available, or skip all
    has_git( '1.6.5' );
    
    # check the git we want to test has a minimum version, or skip all
    has_git( '1.6.5', { git => '/path/to/alternative/git' } );
    
    # normal plan
    plan tests => 2;
    
    # create a new, empty repository in a temporary location
    # and return a Git::Repository object
    my $r = test_repository();
    
    # clone an existing repository in a temporary location
    # and return a Git::Repository object
    my $c = test_repository( clone => [ $url ] );
    # run some tests on the repository
    ...

DESCRIPTION

Test::Git provides a number of helpful functions when running test scripts that require the creation and management of a Git repository.

EXPORTED FUNCTIONS

has_git

    has_git( $version, \%options );

Checks if there is a git binary available, or skips all tests.

If the optional $version argument is provided, also checks if the available git binary has a version greater or equal to $version.

This function also accepts an option hash of the same kind as those accepted by Git::Repository and Git::Repository::Command.

This function must be called before plan(), as it performs a skip_all if requirements are not met.

"has_git" is now obsolete and will print a warning when used. The "test_requires_git" function provided by the Test::Requires::Git module is a much more flexible replacement.

"has_git" will be removed in a future release.

test_repository

    test_repository( %options );

Creates a new empty git repository in a temporary location, and returns a Git::Repository object pointing to it.

This function takes options as a hash. Each key will influence a different part of the creation process.

The keys are:

temp

Array reference containing parameters to File::Temp "tempdir" function.

Default: "<[ CLEANUP =" 1 ]>>

init

Array reference containing parameters to "git init". Must not contain the target directory parameter, which is provided by test_repository() (via File::Temp).

Default: "[]"

The "init" option is only supported with Git versions higher or equal to 1.6.2.rc0.

clone

Array reference containing parameters to "git clone". Must not contain the target directory parameter, which is provided by test_repository() (via File::Temp).

Note that "clone" and "init" are mutually exclusive and that test_repository() will croak if both are provided. This option has no default value, since at least a Git URL must be provided to the "clone" option.

The "clone" option is only supported with Git versions higher or equal to 1.6.2.rc0.

git

Hash reference containing options for Git::Repository.

Default: "{}"

This call is the equivalent of the default call with no options:

    test_repository(
        temp => [ CLEANUP => 1 ],    # File::Temp::tempdir options
        init => [],                  # git init options
        git  => {},                  # Git::Repository options
    );

To create a bare repository:

    test_repository( init => [ '--bare' ] );

To leave the repository in its location after the end of the test:

    test_repository( temp => [ CLEANUP => 0 ] );

Note that since test_repository() uses "git init" to create the test repository, it requires at least Git version "1.5.0.rc1".

ACKNOWLEDGEMENTS

The "clone" option and capability of test_repository() owes a lot to Nathan Nutter (NNUTTER), who wanted to be able to clone into a test repository.
