ObjFW  Artifact [cc7b2ebf4b]

Artifact cc7b2ebf4b43cfbe5e2a188144257ef0e88d80d86396238d149fb0bcbaf48850:

• File tests/OFStreamTests.m — part of check-in [dc0c6c34ab] at 2019-02-17 22:44:23 on branch trunk — tests: Only import ObjFW.h

  This prevents forgetting to add an import to ObjFW.h, as the tests would
  then not compile. (user: js, size: 1800) [annotate] [blame] [check-ins using]
