Question

Good evening everyone

Suppose your code has the following statement:

if (string ends with char 'y') {
  if ((char before last is not 'e') || (char before last is not 'a')) {
    return (something awesome);
  }
}

So that’s simple enough i thought …

Test1:
input = “xy” (last char is y, char before last is not e or a)

Result – partial coverage …

What other tests i am missing? If this was and && instead of ||, i suppose test would be far easier, but || confused me a bit.

Can you suggest Test2,3,n?

Thank you

Answer 1

You want to test for the expected behavior with inputs “ey” and “ay”.

You may find that your method is not doing quite what you think it is. I think || has indeed confused you a bit.
