4 arguments

[frr149]

Is there any workaround when you need 4 inputs, or should I create a Glados4 class and submit a pull request?

You can always use a custom generator to generate more inputs, like this:

Glados(
  any.combine4(any.int, any.int, any.int, (a, b, c, d) => [a, b, c, d])
).test(description, (input) {
  final a = input[0] as int;
  final b = input[1] as int;
  final c = input[2] as int;
  final d = input[3] as int;
  // stuff
});

But yes, in the long term, the cleaner approach would be to create a PR for a Glados 4 class.

FWIW, I think providing extensions for record types would be a nice touch! That way, we could simply write something like:

(any.int, any.int, any.int, any.int).test(description, (input) {
  // stuff
});
