Test::TinyMocker - a very simple tool to mock external modules


Version 0.01


    use Test::More;
    use Test::TinyMocker;

    mock 'Some::Module'
        => method 'some_method'
        => should {
            return $mocked_value;

    # or 

    mock 'Some::Module::some_method'
        => should {
            return $mocked_value;

    # Some::Module::some_method() will now always return $mocked_value;


mock($module, $method, $sub)

This function allows you to overwrite the given method with an arbitrary code block. This lets you simulate soem kind of behaviour for your tests.

Alternatively, this method can be passed only two arguments, the first one will be the full path of the method (pcakge name + method name) and the second one the coderef.

Syntactic sugar is provided (method and should) in order to let you write sweet mock statements:

    # This:
    mock('Foo::Bar', 'a_method', sub { return 42;});

    # is the same as:
    mock 'Foo::Bar' => method 'a_method' => should { return 42 };

    # or:
    mock 'Foo::Bar::a_method' => should { return 42 };

    # or also:
    mock('Foo::Bar::a_method', sub { return 42;});

This module was inspired by Gugod's blog, after the article published about mocking in Ruby and Perl:

This module was first part of the test tools provided by Dancer in its own t directory (previously named t::lib::EasyMocker). A couple of developers asked me if I could released this module as a real Test:: distribution on CPAN, so here it is.
