Given this UML diagram...

How would you create test cases using these examples...

countNonDigits() Testing an empty string. Testing a string that is all digits. Testing a string without digits. Testing a complex string without digits. Testing a string that is alphanumeric. Testing a complex string that is alphanumeric. getEvenCharacters() Testing an empty string. Testing a string with a single, odd character. Testing a string with a single even character. Testing a string of even number length Testing a string of odd number length ramifyString() Testing a single 0 Testing a single double 00 Testing a single 0 and a separate double 00 Testing a triple 000 Testing no 0 characters
