Test2::Todo - TODO extension for Test2.


This is an object that lets you create and manage TODO states for tests. This is an extension, not a plugin or a tool. This library can be used by plugins and tools to manage todo states.

If you simply want to write a todo test then you should look at the todo function provided by Test2::Tools::Basic.


    use Test2::Todo;

    # Start the todo
    my $todo = Test2::Todo->new(reason => 'Fix later');

    # Will be considered todo, so suite still passes
    ok(0, "oops");

    # End the todo

    # TODO has ended, this test will actually fail.
    ok(0, "oops");


reason (required)

The reason for the todo, this can be any defined value.

hub (optional)

The hub to which the TODO state should be applied. If none is provided then the current global hub is used.



End the todo state.


$count = Test2::Todo->hub_in_todo($hub)

If the hub has any todo objects this will return the total number of them. If the hub has no todo objects it will return 0.


How it works

When an instance is created a filter sub is added to the Test2::Hub. This filter will set the todo and diag_todo attributes on all events as they come in. When the instance is destroyed, or end() is called, the filter is removed.

When a new hub is pushed (such as when a subtest is started) the new hub will inherit the filter, but it will only set diag_todo, it will not set todo on events in child hubs.

$todo->end is called at destruction

If your $todo object falls out of scope and gets garbage collected, the todo will end.

Can I use multiple instances?

Yes. The most recently created one that is still active will win.
