【中文标题】在 UITesting 期间导致内存警告和崩溃的背景图像

【英文标题】：Background Image causing memory warning and crash during UITesting

【问题描述】：

我有一个简单的 UITest，它在工具栏上点击一个项目 100 次，运行没有背景图像的测试始终通过，但是当我添加背景图像时，我收到内存警告，然后测试失败。我尝试了许多显示图像的解决方案，大多数都导致相同的结果，内存警告随后崩溃。根据苹果文档，我有一个图像集，由三个尺寸为 3X：2304 X 3072、2X：1536 X 2048 和 1X：768 X 1024 的 png 图像组成。如何添加背景图像以免导致内存问题。

UI测试代码：

func testJustNumberOfRolls() 
    let app = XCUIApplication()
    for _ in 1...100 
        app.toolbars.buttons["Tip2"].tap()
    

视图控制器：

class TestVC: UIViewController     

    override func viewDidLoad() 
        super.viewDidLoad()
        if let image = UIImage(named: "feltSized") 
            self.view.backgroundColor = UIColor(patternImage: image)

【参考方案1】：

更新：我尝试不显示任何图像，这似乎更好。错误显示在“失去与测试管理器服务的连接”。

此时我已经重构了我的应用程序以避免长时间的动画以避免我的测试需要超时，然后重新编码应用程序以隐藏所有图像和背景颜色。即使这样，错误仍然会出现，尽管测试能够运行更长时间。

我能够在一个全新的应用程序上进行复制，只需一个背景图案和一个按钮，即使运行测试超过几分钟也会导致错误，这就是一个全新的应用程序。所以想知道还能做什么，希望这会很快得到解决。
