What kind of tests should NOT be Automated?

• Usability Testing – at times this can be an impossible task to perform by automation as the computer cannot efficiently judge if the system is of any use to its users
• Tests that only need to be executed once – unless the same test needs to be executed for a large dataset then it makes sense to automate
• Tests without predictable results – test automation should give us confidence in the results of the tests. If there are intermittent failures then the tests cannot be reliable and cannot be dependent on
• Tests that need to be verified visually
• Tests that need to be executed quickly. At first, writing an automated test takes longer. If we want a quick check, we should test manually, however, if that test is a good one which should be run regularly, then it should be automated in time
