Test::MockObject and imported functions

Mutant has asked for the wisdom of the Perl Monks concerning the following question:

Hi,

I'm looking for a way of mocking a function that has been imported, e.g.

use Foo qw(bar);

bar(%params); # <-- I want to mock this
[download]

bar() may also be imported implicitly. I know about fake_module(), but the code above will try to call import() on the mock object I've created. Do I have to mock import and somehow hook it into Exporter to export the actual function I want to mock?

Test::MockObject isn't really the right module for this. It relies on method dispatch. Test::MockModule is likely better. You could mock `import()` if you like, but it'll be more work that way.	[reply] [d/l]

You might consider Test::Resub. That would look something like this: `my $handle = Test::Resub->new({ name => 'Foo::bar', code => sub { "mocked out behavior" }, }); # now do something that calls Foo::bar` [download]	[reply] [d/l]
