It is important that test cannot effect the behavior of other tests.
If, for example, there was a test that was testing if an entity went towards grass blocks, but there was a nearby test that had grass blocks, it is possible that the entity would go towards the grass blocks in the other test. This would obviously ruin the test result and so needs to be avoided.
