  The tests uses sqlite memory db, and during the test runs the db is wiped off due to reconnection(connection_recycle_time=3600)[2]. The issue can be seen when tests take more than 1 hour to finish.

  Running full tests suit on slow/loaded systems or running with less
  concurrency it's easy to hit this 1 hour timeout. The tables are
  created once and shared across tests[3]. Due to the timeout tables are
  wiped off so test fails not finding the table, and then later
  table.delete()(this TRUNCATES the table, i.e delete rows) also fails
  due to missing tables.

  For slow systems workaround can be to run set of tests in one go instead of all tests.
  We can also bump the connection_recycle_time for running unit tests to some larger value or provide an option to override it by an env var.
  Also we can check and improve total runtime of tests where possible.
