I want to zip more than 3 values in parameterized testing

Description

SSIA

Alternatively, I want to pass arguments as tuples.

    @Test(arguments: [
        (nil, "name", "description", UIImage()),
        (UIView(), nil, "description", UIImage()),
        (UIView(), "name", nil, UIImage()),
        (UIView(), "name", "description", nil),
    ])
    func didTapShareButton_one_nil(_ argument: (senderView: UIView?, name: String?, description: String?, icon: UIImage?)) {
        presenter.didTapShareButton(argument.senderView, name: argument.name, description: argument.description, icon: argument.icon)
        #expect(routerMock.showActivityCallCount == 0)
    }

Expected behavior

@Test("Can make large orders", arguments: zip(Food.allCases, 1 ... 100, 101 ... 200))
func makeLargeOrder(of food: Food, count: Int, count2: Int) async throws {
  let foodTruck = FoodTruck(selling: food)
  #expect(await foodTruck.cook(food, quantity: count))
}

Actual behavior

I try to achieve this with struct, a build error will occur.

    struct DidTapShareButtonOneNilArgument {
        let senderView: UIView?
        let name: String?
        let description: String?
        let icon: UIImage?
    }
    @Test(arguments: [
        DidTapShareButtonOneNilArgument(senderView: nil, name: "name", description: "description", icon: UIImage()),
        DidTapShareButtonOneNilArgument(senderView: UIView(), name: nil, description: "description", icon: UIImage()),
        DidTapShareButtonOneNilArgument(senderView: UIView(), name: "name", description: nil, icon: UIImage()),
        DidTapShareButtonOneNilArgument(senderView: UIView(), name: "name", description: "description", icon: nil),
    ])
    func didTapShareButton_one_nil(_ argument: DidTapShareButtonOneNilArgument) {
        presenter.didTapShareButton(argument.senderView, name: argument.name, description: argument.description, icon: argument.icon)
        #expect(routerMock.showActivityCallCount == 0)
    }

zip() is part of the Swift standard library. Moving.

(Note that the error you're seeing should be resolved if you update your copy of swift-testing.)

It would be easy to implement a zip() with an arbitrary number of arguments using parameter packs. ref: https://github.com/apple/swift-evolution/blob/main/proposals/0393-parameter-packs.md
