How do you unittest exceptions in Dart?

Question

Consider a function that does some exception handling based on the arguments passed:

List range(start, stop) {
    i         


        

Answer 1

For simple exception testing, I prefer to use the static method API:

Expect.throws(
  // test condition
  (){ 
    throw new Exception('code I expect to throw');
  },
  // exception object inspection
  (err) => err is Exception
);
