Asserts that an
IO
returns an expected value.Asserts that an
IO
returns an expected value.The "returns" value (second argument) must have the same type or be a subtype of the one "contained" inside the
IO
(first argument). For example:assertIO(IO(Option(1)), returns = Some(1)) // OK assertIO(IO(Some(1)), returns = Option(1)) // Error: Option[Int] is not a subtype of Some[Int]
The "clue" value can be used to give extra information about the failure in case the assertion fails.
- obtained
the IO under testing
- returns
the expected value
- clue
a value that will be printed in case the assertions fails
