Given the following code, which is true about the minimum number of test cases

required for full statement and branch coverage

Read P

Read Q

IF P+Q > 100 THEN

Print "Large"

ENDIF

IF P > 50 THEN

Print "P Large"

ENDIF

a) 1 test for statement coverage, 3 for branch coverage

b) 1 test for statement coverage, 2 for branch coverage

c) 1 test for statement coverage, 1 for branch coverage

d) 2 tests for statement coverage, 3 for branch coverage

e) 2 tests for statement coverage, 2 for branch coverage

option -b

I think its  option d

Answer is B since we need minimum number of test cases..

For Branch Coverage: As we have two If statements, we need 2 test cases.

One to test If P+Q>100 and another for If P>50.

hi,
i have just read the question.
some of our friends saying that we require only one testcase for statement coverage.
this is ok for positive testing.for the negative testing we need one more test case.
example:if they are numbers it is ok.but when we give other other than numbers it must give some error message.
    and also i think for black box testing we need 2 test cases for statement coverage for this example/code.as this is white box testing do we need only one statement coverage.
my answer is option e
if my answer is wrong please let me know.
Tara.

ans is B... n tis is a ISTQB question... :) am i rite ?

option - b) is the correct answer.

1) if p = 51, Q= 50 it will cover all the statements. so, one test for statement coverage.

2) for branch coverage:

a)  P+Q> 100 AND P>50 (True)
b)  P+Q < 100 AND P<50 (False)

a) & b) will cover both the branch conditions
yes, it is an ISTQB question.

Answer: B) 1 test for statement coverage, 2 for branch coverage
