如何使用 XCTest 从 iOS 13 删除/重置应用程序？

Question

最近我开始使用 XCTest 测试 iOS 应用程序，但我发现了一些困难，主要困难是删除或重置每个测试类中的应用程序内容。

我目前正在使用 XCode 11 并尝试从 iOS 13 中为每个测试类删除/重置应用程序，我已经尝试过：

• 通过跳板删除应用程序
• 转至应用程序设置删除应用程序

这一步在我的测试中非常重要，因为在每个测试中我都需要创建一个配置文件并登录，所以在下一个测试中我需要从头开始安装应用程序

尝试按应用程序图标比以前的 iOS 版本长一点。

    let springboard = XCUIApplication(bundleIdentifier: "com.apple.springboard")

    func deleteMyApp() {
        XCUIApplication().terminate()

        let icon = springboard.icons["YourAppName"]
        if icon.exists {
            let iconFrame = icon.frame
            let springboardFrame = springboard.frame
            icon.press(forDuration: 5)

            // Tap the little "X" button at approximately where it is. The X is not exposed directly
            springboard.coordinate(withNormalizedOffset: CGVector(dx: (iconFrame.minX + 3) / springboardFrame.maxX, dy: (iconFrame.minY + 3) / springboardFrame.maxY)).tap()

            springboard.alerts.buttons["Delete"].tap()
        }
    }
