In "Records of a table are deleted when there is no `expect.. to .. have_content..`", The mechanism where the test runner polls the UI to see if a condition is met before proceeding. This matters because it prevents the test from finishing (and cleaning the database) before the browser has finished its work.
In "Records of a table are deleted when there is no `expect.. to .. have_content..`", Techniques like transaction or truncation used to reset the database state between tests.

In "Records of a table are deleted when there is no `expect.. to .. have_content..`", A situation where the outcome depends on the timing of uncontrollable events, such as a test runner cleaning the database while a background JS thread is still accessing it.
