Properties of a good unit test ✅

A unit test should have the following properties :

1️⃣ It should be automated and repeatable.

2️⃣ It should be easy to implement.

3️⃣ It should be relevant tomorrow.

4️⃣ Anyone should be able to run it at the push of a button.

5️⃣ It should run quickly.

6️⃣ It should be consistent in its results.

7️⃣ It should have full control of the unit under test.

8️⃣ It should be fully isolated (runs independently of other tests).

9️⃣ When it fails, it should be easy to detect what was expected and determine how to pinpoint the problem.
