如何运行一次swiftXCTesttearDown-HowtorunswiftXCTesttearDownonce

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

我正在使用xcode 8.3.3，swift，我试图让tearDown方法只运行一次。

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

我使用此处提供的解决方案启动应用程序一次：XCTestCase不在setUp类方法中启动应用程序

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

在tearDown方法中，我想注销该应用程序。我只想做一次。

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

XCTest文档有一个类tearDown（）方法，但是当我尝试使用它时 - 它不再能访问应用程序了吗？：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:

这是我在tearDown方法中获得的所有内容，因此它无法访问应用程序上的任何元素：

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

如何在所有测试结束时只在tearDown中运行一次代码？

2 个解决方案

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() {}
}

override class func setUp() {
    super.setUp()
    // Your code goes here
}

override class func tearDown() {
    // Your code goes here
    super.tearDown()
}
