Test Naming and Directory Structure =================================== The directory structure for the unique_ptr class templates differs from the normal test directory naming conventions (e.g. matching the stable name in the standard). Instead of having a [unique.ptr.single] and [unique.ptr.runtime] directory, each containing their own tests, a single directory, "unique.ptr.class", contains both sets of tests. This allows the common behavior of the two unique_ptr specializations to be tested in the same place without duplication. Tests specific to [unique.ptr.single] have the suffix ".single.pass.cpp" and those specific to [unique.ptr.runtime] are named "*.runtime.pass.cpp". Tests for both specializations are named normally.
