-// TODO(syoussefi): re-enable tests on Vulkan once http://anglebug.com/3738 is resolved.  The issue
-// is with WGL where if a Vulkan test is run first in the shard, it causes crashes when an OpenGL
-// test is run afterwards.  AtomicCounter* tests are alphabetically first, and having them not run
-// on Vulkan makes every shard our bots currently make do have at least some OpenGL test run before
-// any Vulkan test. When these tests can be enabled on Vulkan, can replace the current macros with
-// the updated macros below that include Vulkan:
