I get a failure on a test in format.d when I build my own project with unittest. I though importing phobos header would not regenerate their unittest modules.

Any idea of what can cause this issue? I already have reinstalled dmd with visualD completely.

Templates are not compiled fully until you use them.

If a unit test is inside a template, and that template wasn't instantiated inside phobos itself (likely for formatting), it will be instantiated, unit test and all, inside your code that used it.

This is a big limitation on the unit test system. There is no way to say what unit tests to enable, and what to disable. It's just all or nothing.

Quite likely that you use rdmd. It compiles dependencies with same flags as main target so if you do `rdmd -unittest app.d` all modules app imports will be compiled with `-unittest` as well. Using custom build process can fix it.
