# High Level Read Receipt Tests
Tips for writing these tests:
- Break up your tests into the smallest test case possible. The purpose of
these tests is to understand hard-to-find bugs, so small tests are necessary.
We know that Cypress recommends combining tests together for performance, but
that will frustrate our goals here. (We will need to find a different way to
reduce CI time.)
- Try to assert something after every action, to make sure it has completed.
E.g.:
markAsRead(room2);
assertRead(room2);
You should especially follow this rule if you are jumping to a different
room or similar straight afterwards.
- Use assertStillRead() if you are asserting something is read when it was
also read before. This waits a little while to make sure you're not getting a
false positive.
