Thanks in advance
Answer Posted / supriyo sengupta
Let me make this simple:
Let's say, we are testing a piece of end to end
functionality, and it has some 100 test cases.
Now, each of these test cases are given a weightage on the
basis of:
1. Severity (if this test case fails how big will be the
impact: Answer will be high, medium and low)
2. Likelihood of occurrence ( what is the chance of this
test case to fail: for example, if this test case has been
tested in the past several times, or if there is no change
in code/configuratio in that area : hence the answer will
be again: high, medium or low
Now, once we put this high, medium and low qualification on
all the test cases, I will get a grid of 9 boxes (High +
High, High + Medium, High + Low, Meduim + High, etc.) on
Severity and Likelihood of occurrence.
So, the risks are maximum if the test cases in the High+
High grid fails, then it will be High + Medium, then Medium
+High, and so on.
When time is an essence, we may end up testing only the
ones where risks are high as mentioned above.
This concept is called risks based testing.
There are other methods to do this, but for any beginner,
this is good to understand.
Hope it helps.
