Hi All,
In the above mentioned script Statement Coverage means all the statement has been covered or not and Branch Coverage means all the Conditions has been covered or not.

So for statement coverage we need to test the statement
-Print “Large”n
-Print “P Large”
has been executed or not.

For Branch coverage(Condition coverage) we have to check the condition by passing some value and cheking all the conditions (true/false) are executed or not
- P+Q > 100
- P > 50

Please make me understand if i am wrong.

Thanks, Jitu

RE: Statement and Branch Coverage

Coverage is nothing but degree expressed as a percentage to which a specific coverage item has been exercised by a set of tests.

Branch is nothing but conditional transfer of a control from any other statement to other statement.
Here the condition is transftered from the first statement to second statement.
