Log::Any::Test - Test what you're logging with Log::Any

VERSION

version 1.713

SYNOPSIS

    use Test::More;
    use Log::Any::Test;    # should appear before 'use Log::Any'!
    use Log::Any qw($log);
    # ...
    # call something that logs using Log::Any
    # ...
    # 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, [{message => 'msg1', level => 'debug'}, ...]);

DESCRIPTION

"Log::Any::Test" is a simple module that allows you to test what has been logged with Log::Any. Most of its API and implementation have been taken from Log::Any::Dispatch.

Using "Log::Any::Test" signals "Log::Any" to send all subsequent log messages to a single global in-memory buffer and to make the log proxy provide a number of testing functions. To use it, load "Log::Any::Test" before anything that loads "Log::Any". To actually use the test methods, you need to load "Log::Any" and get a log object from it, as shown in the "SYNOPSIS".

METHODS

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

msgs ()

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

  {
    category => 'Foo',
    level => 'error',
    message => 'this is an error'
  },
  {
    category => 'Bar::Baz',
    level => 'debug',
    message => 'this is a debug'
  }
    

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.

category_contains_ok ($category, $regex[, $test_name])

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

category_does_not_contain_ok ($category, $regex[, $test_name])

Tests that no message from a specific category 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.
