How to Dynamically add XCTestCase

I'm writing a UI Test for a white label project where each app has a different set of menu items. The test taps on each menu item and takes a screenshot (using fastlane snapshot).

Currently this all happens inside one XCTestCase called testScreenshotAllMenuItems() which looks like this:

func testScreenshotAllMenuItems() {
    // Take a screenshot of the menu
    openTheMenu()
    snapshot("Menu")
    var cells:[XCUIElement] = []

    // Store each menu item for use later
    for i in 0..<app.tables.cells.count {
        cells.append(app.tables.cells.element(boundBy: i))
    }

    // Loop through each menu item
    for menuItem in cells.enumerated() {
        let exists = menuItem.element.waitForExistence(timeout: 5)
        if exists && menuItem.element.isHittable {
            // Only tap on the menu item if it isn't an external link
            let externalLink = menuItem.element.children(matching: .image)["external link"]
            if !externalLink.exists {
                var name = "\(menuItem.offset)"
                let cellText = menuItem.element.children(matching: .staticText).firstMatch
                if cellText.label != "" {
                    name += "-\(cellText.label.replacingOccurrences(of: " ", with: "-"))"
                }
                print("opening \(name)")
                menuItem.element.tap()
                // Screenshot this view and then re-open the menu
                snapshot(name)
                openTheMenu()
            }
        }
    }
}

I'd like to be able to dynamically generate each screenshot as it's own test case so that these will be reported correctly as individual tests, maybe something like:

[T] Screenshots
    [t] testFavouritesViewScreenShot()        ✓
    [t] testGiveFeedbackViewScreenShot()      ✓
    [t] testSettingsViewScreenShot()          ✓

I've had a look at the documentation on creating tests programmatically but I'm not sure how to set this up in a swifty fashion. - Ideally I would use closures to wrap the existing screenshot tests in to their own XCTestCase - I imagined this like the following but there doesn't appear to be any helpful init methods to make this happen:

for menuItem in cells {
    let test = XCTestCase(closure: {
        menuItem.tap()
        snapshot("menuItemName")
    })
    test.run()
}

I don't understand the combination of invocations and selectors that the documentation suggests using and I can't find any good examples, please point me in the right direction and or share any examples you have of this working.
