+    This test is meant for Lazy Init.
+    We explicitly choose modules which are able to lazy load.
+
+    The ValTest:
+    ------------
+    We load something with `import *`.
+    There is no module from our known ones imported.
+    This means we need stack introspection to find out that this was
+    a star import and we must disable lazyness.
+
+    The OtherTest:
+    --------------
+    We load something normally that should be lazy.
+    After that, we follow with a star import.
+    Now the stack introspection does not work, because the loading is
+    cached. The first import did a lazy load. The following star import
+    needs to undo the lazyness. But now we have a redirected import.
+
+    All tests simply check if the objects are real and not just names.
+    The <module>_loaded tests prevend upcoming internal dependencies.
+
+    To make sure that Shiboken is really not involved, it is checked
+    and really imported afterwards (ensuring nothing is misspelled).
