Rule proposal: avoid before / after hooks

[lo1tuma]

Using before or after hooks is almost always a sign that you use shared state between multiple tests. This could lead to unwanted side-effects, e.g. some tests only pass/fail if the tests are executed in a specific order.

Should this then also forbid beforeEach and afterEach? I'm thinking yes as it follows the same shared state problem.

[lo1tuma]

You are right, the same problem could be created by beforeEach and afterEach.
I think if someone needs to distinguish between all and every hooks we can always add an option to the rule later.
