[erlang-questions] eunit failure - "*** test module not found ***"
Tue Mar 16 18:39:15 CET 2010
I think this occurs when you omit a leading underscore
on an eunit macro in a test-generating function.
For example, say you write a simple test function using a basic macro:
basic_test() -> ?assert( 1 + 1 =:= 2 ).
Then you decide to convert it to a test-generating function, you should
append an '_' to the function name, and
prepend an '_' to the macro name:
fancy_test_() -> ?_assert( 1 + 1 =:= 2 ).
but if you forget to change the macro name:
bad_test_() -> ?assert( 1 + 1 =:= 2 ).
then you get the error as you describe:
*** test module not found ***
Failed: 0. Skipped: 0. Passed: 0.
One or more tests were cancelled.
The 'ok' value in the error message is the result of
evaluating the function returned by the macro,
so your mistake is on a macro that returns 'true'.
