New! 7 Common Mistakes To Avoid When Writing Tests

Feb 20, 2022

I was talking with a fellow programmer the other day about a poor test that we were reviewing and we got onto the subject of what makes a poor test. The test in question had a reliance on a previous test being run, and the problem we encountered was that on some systems the dependent test was run after this test, which caused it to fail.

This also caused some headaches in local development as it couldn't be run in isolation. We had to ensure that both tests were run, in the correct order.

After fixing the tests so that they could be run independently I created a list of some common problems that programmers might come across when writing tests. These rules can be applied to most coding test, not just unit tests or behavioural tests.
