Test::MockObject and imported functions

[Mutant]

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

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.

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
