    Preondition Violations
    Expression shouldNeverHappen("Text is null, but null is not allowed") is a method call throwing exception(s) that should be caught by a try block that will be extracted
    • Inline private method shouldNeverHappen
    Expression shouldNeverHappen("Text is null, but null is not allowed") is a void method call, and thus it cannot be parameterized
