Description Carlos Goncalves 2020-02-17 12:50:09 UTC 
Downstream CI warns for occasional failures in test octavia_tempest_plugin.tests.scenario.v2.test_amphora.AmphoraScenarioTest.test_amphora_list_and_show. The test failure is observed when multiple Octavia tests are run concurrently. The tracebacks can be distinct on multiple runs but are always at the same assert.

The test gets a list of amphorae in [1] and later in [2] it tests all of the fields from the amphora list match those from a show. In-between these two, there are other tests running that create/update/delete amphorae.
