Solved Exercise on Modified Condition Decision Coverage (MCDC)

Question #1: Solution

Write Test requirements and Test cases required according to MCDC criteria.

if ((A > 10) && (B < 5) || (C == 0)) {
    // Do something
} else {
    // Do something else
}

Question #2:

Design a set of test cases to achieve 100% MCDC for the following C++ if statement:

if ((X == 5) || (Y > 10) && (Z < 15)) {
    cout << "Condition passed";
} else {
    cout << "Condition failed";
}

Question #3:

Write the minimal test cases required to achieve MCDC for the following C++ code:

if ((A > 20) && (B < 30) || (C == 0) && (D != 5)) {
    cout << "Conditions met";
} else {
    cout << "Conditions not met";
}

Question #4:

Generate test cases to achieve MCDC coverage for the following C++ if statement:

if ((X == 5) && (Y < 5)) {
    cout << "Both conditions true";
} else {
    cout << "One or both conditions false";
}

Question #5:

Write the test cases to achieve MCDC for the following C++ condition:

if ((A > 5) && (B < 10) || (C == 0)) {
    cout << "Conditions met";
} else {
    cout << "Conditions not met";
}

Question #6:

Generate the test cases to achieve MCDC for the following C++ ternary operator:

(X > 5) ? (Y < 10) : (Z == 0);

Question #7:

Design test cases to achieve MCDC for the following C++ decision:

if ((A > 10) && (B < 5) || (C != 0)) {
    cout << "Valid condition";
} else {
    cout << "Invalid condition";
}

Question #8:

Generate test cases to achieve MCDC for the following C++ code:

if ((X == 5) && (Y > 10)) {
    cout << "Condition met";
} else {
    cout << "Condition not met";
}
