A TEST_F / TEST_P body is a member function of a class derived from its
fixture, so its unqualified names find the fixture's nested types (its bases'
included) before the enclosing namespaces'. And since the index names a
function's local class after the function, every TEST_F body's local `FakeWF`
or `MyManager` shared one qualified name: a class local to a function is now
visible only from inside that function, and a namesake class's methods are
its own body's.
