EarlGrey同步的问题总是超时

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,它基本上会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.我检查屏幕截图,正确的屏幕显示失败.

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"
  }
]

如果我关闭同步它会工作:

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

有什么我做错了吗？我的所有测试似乎都适用于同步关闭.我应该把它关掉吗？

你不应该关闭同步 - 这就是EarlGrey EarlGrey的原因,让你的测试变得稳定和有用.

但是,看起来你有一些动画或延迟了performSelector,EarlGrey正在跟踪它,以使它始终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GREYConfiguration.h,您可以找到各种配置变量,您可以根据应用程序的行为进行更改.
