Test::MockDateTime - mock DateTime->now calls during tests
version 0.01
use Test::More; use Test::MockDateTime; use DateTime; on '2013-01-02 03:04:05' => sub { # inside this block all calls to DateTime::now # will report a mocked date. my $now = DateTime->now; is $now->ymd, '2013-01-02', 'occured now'; }; done_testing;
Getting the current time sometimes is not very helpful for testing scenarios. Instead, if you could obtain a known value during the runtime of a testcase will make your results predictable.
This simple module allows faking a given date and time for the runtime of a subsequent code block. By default the on keyword is exported into the namespace of the test file. The date to get mocked must be in a format that is recognized by DateTime::Format::DateParse.
on
on '2013-01-02 03:04:05', sub { ... };
is basically the same as
{ my $now = DateTime::Format::DateParse->parse_datetime( '2013-01-02 03:04:05' ); local *DateTime::now = sub { $now->clone }; ... everything from code block above }
A drawback when relying on this module is that you must know that the module you are testing uses DateTime->now to obtain the current time.
DateTime->now
mocks date and time and then executes code
