Multiple choice technology testing

How many test cases are necessary to cover all the possible sequences of statements (paths) for the following program fragment? Assume that the two conditions are independent of each other: if (Condition 1) then statement 1 else statement 2 fi if (Condition 2) then statement 3 fi

  1. 2 Test Cases

  2. 3 Test Cases

  3. 4 Test Cases

  4. Not achievable

A Correct answer
Explanation

With two independent conditions in nested if statements, we need 2 test cases: (1) Condition 1 true, (2) Condition 1 false. When Condition 1 is false, we never reach Condition 2 due to the else branch. When Condition 1 is true, we always execute statement 3 regardless of Condition 2. Thus only 2 paths are possible.
