EarlGrey同步的问题总是超时

Question

我对伯爵的同步功能有问题。我试图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出现。

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，我得到以下错误消息。我检查截图和正确的屏幕显示在失败。

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，它就能工作：

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

我做错什么了吗？当同步关闭时，我的所有测试似乎都能很好地工作。我应该把它关了吗？

您不应该关闭同步-这正是EarlGrey EarlGrey的原因，并使您的测试稳定和有用。

然而，看起来你有一些动画或延迟的performSelector，EarlGrey正在跟踪，以使它总是认为你的应用程序很忙。您可以调整的一件事是，如果您查看标题GREYConfigur.h，您可以根据应用程序的行为找到可能更改的各种配置变量。
