+"""Tests for how well Pulp can deal with duplicate uploads.
+
+This module targets `Pulp #1406`_ and `Pulp Smash #81`_. The test procedure is
+as follows:
+
+1. Create a new feed-less repository.
+2. Upload content and import it into the repository. Assert the upload and
+   import was successful.
+3. Upload identical content and import it into the repository.
+
+The second upload should silently fail for all Pulp releases in the 2.x series.
