I'm not sure I'm getting my point across about why isolated tenants are
absolutely essential for parallel execution of Tempest...
If you have test cases running within the same tenant that are testing
the creation, modification and destruction of resources (say, server
instances), and test cases that are testing the listing and showing of
resources, and you run them in parallel, then the tests need to take
into account what the other test cases are doing. This means more
complex code that must be injected into the listing test cases to filter
out unexpected results that suddenly appear in the results for things
like GET /servers because other test cases have added or destroyed
resources between the time when the listing test case originally
determined the number of server resources before adding the server
resources that its own test case uses when doing assertions.
The reason tenant isolation was added to Tempest was to get rid of this
I honestly feel like we are debating getting rid of tenant isolation for
silly micro-optimization reasons and completely missing the big picture
that isolation/containerization of the test case fixtures means they can
be run in parallel.
