NAME

Test::Log::Dispatch -- Test what you are logging

SYNOPSIS

        use Test::More;
        use Test::Log::Dispatch;

        my $log = Test::Log::Dispatch->new();

        # ...
        # call something that logs to $log
        # ...

        # now test to make sure you logged the right things

        $log->contains_ok(qr/good log message/, "good message was logged");
        $log->does_not_contain_ok(qr/unexpected log message/, "unexpected message was not logged");
        $log->empty_ok("no more logs");

        # or

        my $msgs = $log->msgs;
        cmp_deeply($msgs, ['msg1', 'msg2', 'msg3']);

DESCRIPTION

`Test::Log::Dispatch' is a `Log::Dispatch' object that keeps track of everything logged to it in memory, and provides convenient tests against what has been logged.

CONSTRUCTOR

The constructor returns a `Test::Log::Dispatch' object, which inherits from `Log::Dispatch' and contains a single `Log::Dispatch::Array' output at 'debug' level.

The constructor requires no parameters. Any parameters will be forwarded to the `Log::Dispatch::Array' constructor. For example, you can pass a min_level to override the default 'debug'.

METHODS

The test_name is optional in the *_ok methods; a reasonable default will be provided.

contains_ok ($regex[, $test_name])

        Tests that a message in the log buffer matches $regex. On success,
        the message is removed from the log buffer (but any other matches
        are left untouched).

does_not_contain_ok ($regex[, $test_name])

Tests that no message in the log buffer matches $regex.

empty_ok ([$test_name])

        Tests that there is no log buffer left. On failure, the log buffer
        is cleared to limit further cascading failures.

contains_only_ok ($regex[, $test_name])

        Tests that there is a single message in the log buffer and it
        matches $regex. On success, the message is removed.

clear ()

Clears the log buffer.

msgs ()

        Returns the current contents of the log buffer as an array
        reference, where each element is a hash containing a message and
        level key.

TO DO

• Allow testing of log levels.
