The first time I ran against a development environment where the topologies
were running and so new data (outside the e2e tests) was hitting the search
indices. I ran the e2e tests and had quite a few failures.
Then I stopped the topologies and since then either all tests pass on the
first try or a couple fail and the automated retry kicks in which leads to
eventual success.
I am just not sure if that is coincidence or if we need to update the
README so that everyone knows to stop the topologies when running these tests.
