異常：OpenQA.Selenium.WebDriverException：

Question

當我使用C＃Nunit使用以下配置Protractor.net運行測試時，拋出以下異常

 1. "NUnit" version="3.11.0"
 2. "NUnit3TestAdapter" version="3.12.0"
 3. "Protractor" version="0.12.0"
 4. "Selenium.WebDriver" version="3.141.0"
 5. "Selenium.WebDriver.ChromeDriver" version="2.36.0"
 6. Chromebrowser Version :  65.0.3325.162

angular.version {完整：“ 1.6.9”，主要：1，次要：6，點號：9，代號：“ fiery-basilisk”}

下面的示例代碼已用於測試，但在NgBy.Repeater中失敗

private IWebDriver driver;
driver = new ChromeDriver();
driver.Manage().Timeouts().AsynchronousJavaScript = TimeSpan.FromSeconds(60);
public void uitest()
{
try {
      ngDriver.Navigate().GoToUrl("");           
      ngDriver.FindElement(By.Id("userNameInput")).SendKeys("");            
      ngDriver.FindElement(By.Id("passwordInput")).SendKeys("");
      ngDriver.FindElement(By.Id("submitButton")).Click();
      string text=ngDriver.FindElements(NgBy.Repeater(""))[0].Text;
      Assert.AreEqual("Dashboard", text);
}catch(Exception e)
{
Console.WriteLine("Exception :"+e.ToString());
Assert.True(false);
}
driver.Quit();
}

例外情況：

OpenQA.Selenium.WebDriverException: The HTTP request to the remote WebDriver server for URL http://localhost:61649/session/f5f68e3d39a9e0e5adee0c5d76acd9d1/execute_async timed out after 60 seconds. ---> System.Net.WebException: The operation has timed out

您需要將IgnoreSynchronization設置為true並為角度頁面調用WaitForAngular()方法

ngDriver.IgnoreSynchronization = true;
ngDriver.WaitForAngular();

在SetUp()方法中添加此代碼，或嘗試在遇到問題的行中使用
