This is missing the short argument.

Short is optional param of value -32768, the test is checking for optional params to be used correctly and I wanted to keep this convention for this case.

  • These 3 are not testing optional parameters.
  • Also, for the cases that call GetDefaultAndRequiredParam - add comments mentioning what optional type is being tested.

Do the changes in this PR also affect passing a negative number as an argument to a method?

("test.GetDefaultAndRequiredParamMixedTypes(\"a\")", TString("a; -1; False")),
("test.GetDefaultAndRequiredParamMixedTypes(\"a\", 23)", TString("a; 23; False")),
("test.GetDefaultAndRequiredParamMixedTypes(\"a\", 23, true)", TString("a; 23; True"))
