man Test::Log::Dispatch (3): 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.
