2 Documentation Collection of test cases to validate OVSDB projects bugs.
4 ... TODO: there seems to be some thoughts around never having one-off bug reproduction
5 ... test cases, but rather they should exist as another test case in some appropriate
6 ... suite. Also it was suggested that using bug ids for test case names was not ideal
7 ... this to-do is written in case it's decided to refactor all of these test cases out
8 ... of this suite and/or to rename the test cases at a later time.

30 Bug 7414 Same Endpoint Name
31 [Documentation] To help validate bug 7414, this test case will send a single rest request to create two
32 ... ports (one for each of two OVS instances connected). The port names will be the same.
33 ... If the bug happens, the request would be accepted, but internally the two creations are seen as the
34 ... same and there is a conflict such that neither ovs will receive the port create.

59 Bug 7414 Different Endpoint Name
60 [Documentation] This test case is supplemental to the other test case for bug 7414. Even when the other
61 ... test case would fail and no ovs would receive a port create because the port names are the same, this
62 ... case should still be able to create ports on the ovs since the port names are different. However,
63 ... another symptom of this bug is that multiple creations in the same request would end up creating
64 ... all the ports on all of the ovs, which is incorrect. Both test cases check for this, but in the
65 ... case where the other test case were to fail this would also help understand if this symptom is still
