iii) Cumulative Cases Pros and Cons
These cases are those that depend on previous cases to run.
When you have to run tests 1-10 before you can test 11.
The tester goal is to keep the test as self-standing as possible.
This gives the greatest flexibility in scheduling testing,
and cuts down on maintenance time and its maintenance cost.
If test case depends on another test case then and only take a reference of previous test case. If so,
the test must be cumulative. Whenever it required, offer an alternative to a previous test.
This implies they can use the data created in a previous test but they could also use other data.
Generally keep references to other tests as generic as possible consistent with accuracy.
Don't refer to test cases by number only.
