The default for packages without tests should be to create an image to make sure the package can be installed.

When you try to run melange test on a package that doesn't have a test specified some output dumps and it returns 0.

I can understand not wanting to return non zero if melange test was empty but I think it'd make sense for an empty melange test to at least install the package you were trying to test. That seems like a sane null test for a package.

Without this I found myself scripting various alternatives that amount to make local-wolfi then apk add.... when melange could do that by default.
