With automated testing and test-driven development, it's important to see a test fail.\nIf a test passes straight away, how do you know that you're testing the right thing? You could be accidentally testing a different piece of functionality, or it could be a false positive.<\/p>\n\n

If the functionality already exists, do you need another test for it?<\/p>\n\n

When you see a test fail, you know that the functionality hasn't been implemented, that you're testing the correct thing, and you have a clear goal to work towards.<\/p>\n\n

If you're fixing a bug, writing a test and seeing it fail verifies the bug exists and that, once the bug is fixed, the test will pass.<\/p>\n\n

Usually, you can anticipate why a test will fail as it evolves and know when it will pass. If a test passes before I expect, I'm immediately sceptical and will look into why rather than assuming it passed for the right reasons.<\/p>\n\n ", "format": "full_html", "processed": "\n
