How to run swift XCTest tearDown once

Question

I am using xcode 8.3.3, swift, and I am trying to get the tearDown method to run only once.

I launch the application once with the solution provided here: XCTestCase not launching application in setUp class method

In the tearDown method, I want to logout of the application. I only want to do this once.

The XCTest documentation has a class tearDown() method, but when I try to use it - it doesn't have access to the application anymore?: https://developer.apple.com/documentation/xctest/xctestcase/understanding_setup_and_teardown_for_test_methods

This is all I get when I am in the tearDown method and so it can't access any elements on the application anymore:

How can I run the code in the tearDown just once at the end of all tests?

You can do something like this

import XCTest

class TestSuite: XCTestCase {

    static var testCount = testInvocations.count

    override func setUp()
    {
        super.setUp()

        TestSuite.testCount -= 1
    }

    override func tearDown()
    {
        if TestSuite.testCount == 0 {
            print("Final tearDown")
        }

        super.tearDown()
    }

    func testA() {}
    func testB() {}
    func testC() {}
}
