C# Selenium WebDriver 测试在连续运行时失败但在单独运行时成功

所以我有一个 .feature 文件，我在其中添加了 4 个场景。

.feature 文件

Feature: BleKeys beheren 
Het beheren van BLE-keys 
d.m.v. de WebInterface. 
 
@notfs 
Scenario: BLE-key toevoegen aan database 
    Given I'm at the BleKey/Create page. 
    And I have entered acceptable BLE-data. 
    When I press Create 
    Then The BLE-key should be added to the database. 
 
@notfs 
Scenario: BLE-key data aanpassen 
    Given There is a BleKey in the database. 
    And I'm at the BleKey/Edit page of that BleKey 
    When I edit the MAC-Adress 
    And I edit the Conditional Report 
    And I edit the Flag 
    And I edit the Distance 
    And I edit the Reference 
    And I edit the ExtraCfg 
    And I press Save 
    Then The BleKey should have changed correctly. 
 
@notfs 
Scenario: BLE-key data verwijderen 
    Given There is a BleKey in the database. 
    And I navigate to the Delete page of that BleKey 
    When I press Delete 
    Then The BleKey should be deleted. 
 
@notfs 
Scenario: BLE-key data van 1 sleutel bekijken 
    Given There is a BleKey in the database. 
    And I navigate to the Details page of that BleKey 
    Then The correct data of that BleKey should be displayed 

现在，当我在 Visual Studio(ReSharper 单元测试 session 窗口)中单独运行这些测试时，它们都成功了，但是当连续运行时，第一个成功，但任何连续测试都失败，并出现以下异常:

OpenQA.Selenium.WebDriverException : Unexpected error. System.Net.WebException: Unable to connect to the remote server ---> System.Net.Sockets.SocketException: No connection could be made because the target machine actively refused it 127.0.0.1:5595

如您所见，测试尝试连接到某个本地 IP 地址，而它应该导航到以下基本 URL:

http://localhost:58759/ + controller + method depending on the test.

我在步骤文件中创建了 WebDriver 实例。像这样:

public class BleKeyBeherenSteps 
    { 
        public static RemoteWebDriver RemoteWebDriver = new ChromeDriver(); 
        public WebinterfaceSelenium SeleniumTest = new  
        WebinterfaceSelenium(RemoteWebDriver); 
        public Navigate Navigate = new Navigate(RemoteWebDriver); 
        public Check Check = new Check(RemoteWebDriver); 
        public Edit Edit = new Edit(RemoteWebDriver); 
        public Delete Delete = new Delete(RemoteWebDriver); 
        private readonly BeheerContext _db = new BeheerContext(); 
    } 

在我的方法中，我是这样导航的:

Driver.Navigate().GoToUrl(Adress + BleKeyIndexUrl); 

其中地址 = "http://localhost:58759/ "

BleKeyIndexUrl = "BleKeys/Index"

因此出于某种原因，WebDriver 导航到本地 IP 地址而不是本地主机地址。

编辑:每次测试后我关闭驱动程序:Driver.Quit(); 我的猜测是，由于某种原因，在第一次测试后，Driver.Url 属性丢失了。

请您参考如下方法:

不要担心本地主机到 IP 地址的歧义，本地主机通常解析为 127.0.0.1。

连续单元测试失败通常是由于在应用程序代码中使用静态声明引起的。今天早上我处理了这个问题，我不得不在每个单元测试开始时在我的应用程序深处重置一个麻烦的静态变量。
