Answer / paulo
Yo can prepare a set of input values to go trough both
conditions, that would be one test case.
You can prepare another set of values to take the false path
in condition1 (the only one that have statement when false)
i.e:
If x > y then X=1
fi
If f > v then F=1
fi
Test case 1 would be X = 3, Y = 2, F=3, V=2
Test case 2, would be x= 3, Y = 4, F=3, F=4
So the answer would be 2 test cases, and as far as i can
see, that would be the option A, that have a missed number

Answer / madhavi
we prepare 4 test cases for path coverage for this question.why becoz we have to find out number of possible ways for path coverage.
| Is This Answer Correct ? | 28 Yes | 4 No |
Answer / nithya
Path Coverage ensures covering of all the paths from start to end.
So the correct answer is 4 test cases.
| Is This Answer Correct ? | 12 Yes | 2 No |
Answer / jagadish
for path coverage we have to check all the paths its like
boolean expression, (true, true) is one path, (true, false)
is the second path, (false, true) is third path and both
false is the fourth path. so to cover 100% path coverage it
needs 4 test cases to achieve it. Please clarify if i am wrong.

Answer / anand
It is 4 test cases for the path coverage. The first condition has two path Statement 1 and Statement 2 (True and False). Same way the second condition also has two paths Statement 3 and nothing/null ( as there is no else for the second condition ) but it still is path (there is no statement but still there is a path compiler can take...)
| Is This Answer Correct ? | 5 Yes | 2 No |
Answer / mandokar
It requires only 2 test cases as in the question he
mentioned "path", if it was condition then the answer could
have been 4 as jagdish said.

Answer / sachin karla
actually in statement testing,what happens like,3 cases arise in the program and it proceeds as:
case 1:the '+' sign becomes a 'space'.
case 2:'%xx' becomes byte with hexadecimal value 'xx'.
case 3:other alphanumeric char map themselves.
So guys,think about it and make a proper testing over it..
