meck:unload is undefined?

[ostinelli]

Using this module, and R15B01:

-module(example).
-compile(export_all).

get_config() ->
    mocked:myfun("test.cfg").

-ifdef(TEST).
-include_lib("eunit/include/eunit.hrl").

get_config_test_() ->
    meck:new(mocked),
    meck:expect(mocked, myfun, fun(Filename) -> ok end),
    ?_assertEqual(ok, get_config()),
    ?_assert(meck:validate(mocked)),
    meck:unload(mocked).
-endif.

Compiling and running tests:

1> c(example, [{d, 'TEST'}]).
example.erl:19: Warning: variable 'Filename' is unused
example.erl:20: Warning: a term is constructed, but never used
example.erl:21: Warning: a term is constructed, but never used
{ok,example}
12> example:test().           
undefined
*** test module not found ***
::ok

=======================================================
  Failed: 0.  Skipped: 0.  Passed: 0.
One or more tests were cancelled.
error

However, if I comment the line meck:unload(mocked). then test passes successfully.

Sorry for the late reply. The issue occurs because the trailing underscore (get_config_test_) tells EUnit that the function is a test generator, not a test. EUnit then expects the function to return a list of tests instead.

indeed, it's a generator. i guess then meck has to be used within a test. i haven't find anything clarifying that in docs.

thank you,

Meck is not tied to a specific test library or framework. It just has a functional API that you can use in any code, really.
