[erlang-questions] How to meck?

[Bohuslav Svancara]

Thank you, but it does not help.

---------- modified tested module:
-module(meck_module_for_test).
-compile(export_all).
a() -> a.
call_a() -> *meck_module_for_test:a().* % changed line

-------  testing module "meck_test" is the same (se below)

Result:

1> meck_test:test().
Result of call_a: #Fun<meck_test.1.84433456>
Result of a: #Fun<meck_test.1.84433456>
Valid: true
ok
