EarlGrey 同步总是超时的问题

Question

我在使用 EarlGrey 的同步功能时遇到了问题。我正在尝试为我的应用程序创建一个简单的测试示例，基本上检查登录按钮是否显示。

func testExample() {
    let success = GREYCondition(name: "Wait for action view controller", block: { () -> Bool in
        if let rootVC = UIApplication.shared.keyWindow?.rootViewController, rootVC is ValuePropsViewController {
            return true
        }
        else {
            return false
        }
    }).wait(withTimeout: 10)
    GREYAssertTrue(success, reason: "Action view controller should appear within 5 seconds")
    EarlGrey.select(elementWithMatcher: grey_accessibilityID("loginButton")).assert(grey_sufficientlyVisible())
}

但是，它总是超时，我收到以下错误消息。我检查了屏幕截图，失败时显示的是正确的屏幕。

Exception Name: AssertionFailedException
Exception Reason: Timed out while waiting to perform assertion.
Exception with Assertion: {
  "Assertion Criteria" : "assertWithMatcher: matcherForSufficientlyVisible(>=0.750000)",
  "Element Matcher" : "(respondsToSelector(accessibilityIdentifier) && accessibilityID('loginButton'))"
}

Exception Details: Error Trace: [
  {
    "Description" : "Failed to execute block because idling resources below are busy.",
    "Description Glossary" :     {
      "animateWithDuration:delay:options:animations:completion:" : "<NSObject: 0x610000203a30> caused the App to be in busy state for 6.8 seconds.",
      "performSelector @selector(tick) on VAAppDelegate" : "Delayed performSelector caused the App to be in busy state for 2 seconds."
    },
    "Domain" : "com.google.earlgrey.GREYUIThreadExecutorErrorDomain",
    "Code" : "0",
    "File Name" : "GREYUIThreadExecutor.m",
    "Function Name" : "-[GREYUIThreadExecutor executeSyncWithTimeout:block:error:]",
    "Line" : "235",
    "TestCase Class" : "EarlGreyVidaTests.MyFirstEarlGreyTest",
    "TestCase Method" : "testExample"
  },
  {
    "Description" : "Failed to execute assertion within 30 seconds.",
    "Domain" : "com.google.earlgrey.ElementInteractionErrorDomain",
    "Code" : "4",
    "File Name" : "GREYElementInteraction.m",
    "Function Name" : "-[GREYElementInteraction assert:error:]",
    "Line" : "418",
    "TestCase Class" : "EarlGreyVidaTests.MyFirstEarlGreyTest",
    "TestCase Method" : "testExample"
  }
]

如果我关闭同步，它会起作用：

GREYConfiguration.sharedInstance().setValue(false, forConfigKey: kGREYConfigKeySynchronizationEnabled)

我做错了什么吗？我的所有测试似乎都可以在同步关闭的情况下正常运行。我应该把它关掉吗？

Answer 1

您不应该关闭同步 - 这就是使 EarlGrey 成为 EarlGrey 并使您的测试稳定有用的原因。

但是，您似乎有一些 EarlGrey 正在跟踪的动画或延迟的 performSelector，以使其始终认为您的应用程序很忙。您可以调整的一件事是，如果您查看 header、GREYConfiguration.h，您会发现各种配置变量，您可能会根据应用的行为进行更改。
