I have test file with same name for unit and my other custom suite name, inside the same project, also it's namespaced (which is of course the namespace would be the same for both unit and my other suite test), so when I try to run the test, error message occurs due to class name has been declared.
PHP Fatal error: Cannot declare class Developtest\PriceCest, because the name is already in use in develop/tests/unit/PriceCest.php on line 5
PriceCest.php with namespace Developtest\Another suite name file: PriceCest.php with namespace Developtest\
Codeception version: 2.2.5
It is your fault, rename one test.
