Tell me number of test cases required for full statement and branch coverage: Read P Read Q ..

Answer / saurabh_g

Since both the conditions are independent of each other :

(1) Branch Coverage :

2 Test cases are required.

1st test case : When P+Q > 100 is True (1st branch)
2nd test case : When p > 50 is True (2nd Branch)

(2) 100 % Statement coverage : Each executable statement
executed atleast once.

Again 2 Test cases are required.

1st test case : When P+Q > 100 is True
2nd test case : When p > 50 is True

(3) Path coverage :

4 Test cases are required because 4 paths are possible.

1st : When P+Q > 100 is true but P>50 is false
2nd : When both "P+Q > 100" and "P>50" are true.
3rd : When both "P+Q > 100" and "P>50" are false.
4th : When P+Q > 100 is false but P>50 is true.
