Using assertSame to improve assertEquals

[peter279k]

Changed log

• Some assertEquals is not correct approach to assert values. It should use the assertSame to assert that expected is same as result because some result is InputDatatum object and it's not same as string type.
  Using the casting syntax to convert above object to string before doing some assertions.

Thank you @peter279k.

This is certainly an improvement to the way the unit tests work. What do you think about introducing the Stringable interface on the Input Datum classes, so it will become more obvious that the object can be cast to a string?

Hi @g105b, thanks for your reply. I think this work you mention is about enhancement.

I think it's okay to improve that. If you also want to do that, please submit the issue and describe current approach so that I can follow the step to implement that :).
