C#specflow无法修复:错误CS1029 #error:'生成错误:序列不包含任何元素'

Question

我试图制作我的第一个自动测试并且我不断收到此错误:错误CS1029 #error:'生成错误:序列不包含任何元素'.

有人可以帮忙吗？

我的specflow feture:

Feature: SpecFlowFeature1
    In order to see and check my todos
    As planning user
    I want to create and see my todos and done todos

@mytag
Scenario: Check default number of todos
    Given user is on todolist.me main page
    Then user sees list of 7 todo''s

Scenario Outline: Check todos creation
    Given user is on todolist.me main page
    When user creates new todo with content: <content>
    Then user sees todo with content: <content>

Scenario Outline: Chech todos can be checked and mark as done
    Given user is on todolist.me main page
    When user creates new todo with text: <text>
    Then user checks the todo with text: <text>
    Then user sees no todo with text: <text>
    Then user sees done todo with text: <text>

    Examples: 
    | content         |
    | just plain text |
    | 1234567890      |
    | ~!@#$%^&*()_-+<>|

    Examples: 
    | text               |
    | customToDoText     | 

我的配置:

using System;
using System.Collections.Generic;
using System.Linq;
using System.Text;
using System.Threading.Tasks;
using TechTalk.SpecFlow;
using OpenQA.Selenium;
using OpenQA.Selenium.Chrome;

namespace UnitTestProject1
{
    [Binding]
    public class Conf
    {
        private static IWebDriver driver = new ChromeDriver();

        public static IWebDriver GetDriver()
        {
            driver.Manage().Timeouts().ImplicitWait = TimeSpan.FromSeconds(5);
            driver.Manage().Window.Maximize();
            return driver;
        }

        [AfterTestRun]
        public static void AfterTestRun()
        {
            driver.Quit();
        }
    }
}

我的步骤:

using System;
using TechTalk.SpecFlow;
using OpenQA.Selenium;
using OpenQA.Selenium.Chrome;
using NUnit.Framework;
using OpenQA.Selenium.Interactions;
using System.Collections.Generic;
using System.Linq;

namespace UnitTestProject1
{
    [Binding]
    public class SpecFlowFeature1Steps
    {
        private static IWebDriver driver = Conf.GetDriver();

        [Given(@"user is on todolist.me main page")]
        public void NavigateToTodoList()
        {
            driver.Navigate().GoToUrl("http://todolistme.net");
        }

        [When(@"user creates new todo with content: (.*)")]
        public void WhenUserCreatesNewTodoWithContent(String todoContent)
        {
            driver.FindElement(By.Id("newtodo")).SendKeys(todoContent);
            new Actions(driver).SendKeys(Keys.Enter).Build().Perform();
        }

        [When(@"user creates new todo with text: (.*)")]
        public void WhenUserCreatesNewTodoWithText(String todoText)
        {
            driver.FindElement(By.Id("newtodo")).SendKeys(todoText);
            new Actions(driver).SendKeys(Keys.Enter).Build().Perform();
        }


        [Then(@"user sees list of (.*) todo's")]
        public void ThenUserSeesListOfTodoS(int count)
        {
            Assert.AreEqual(count, driver.FindElements(By.XPath("//span[contains(@id, 'mytodo')]")).Count);
        }


        [Then(@"user sees todo with content: (.*)")]
        public void ThenUserSeesTodoWithContent(String todoContent)
        {
            List<IWebElement> list = driver.FindElements(By.XPath("//span[contains(@id, 'mytodo')]")).ToList();
            IWebElement elem = list.Find(x => x.Text.Equals(todoContent));
            Assert.AreEqual(todoContent, elem.Text);
        }

        [Then(@"user checks the todo with text: (.*)")]
        public void ThenUserChecksTheTodoWithText(String todoText)
        {
            var listItem = driver.FindElement(By.XPath("//li[./span[contains(text(), 'customToDo')]]/input"));
            new Actions(driver).Click(listItem);
        }

        [Then(@"user sees no todo with text: (.*)")]
        public void ThenUserSeesNoTodoWithText(String todoText)
        {
            List<IWebElement> list = driver.FindElements(By.XPath("//ul[contains(@id, 'mytodos')]//span[contains(@id, 'mytodo')]")).ToList();
            IWebElement elem = list.Find(x => x.Text.Equals(todoText));
            Assert.AreNotEqual(todoText, elem.Text);
        }

        [Then(@"user sees done todo with text: (.*)")]
        public void ThenUserSeesDoneTodoWithText(String todoText)
        {
            List<IWebElement> list = driver.FindElements(By.XPath("//ul[contains(@id, 'mydonetodos')]//span[contains(@id, 'mytodo')]")).ToList();
            IWebElement elem = list.Find(x => x.Text.Equals(todoText));
            Assert.AreEqual(todoText, elem.Text);
        }
    }
}

完成所有这些后,我收到一个错误:

Error   CS1029  #error: 'Generation error: Sequence contains no elements'

不知道该怎么做才能解决这个问题.请帮忙.THX提前.

我知道答案已被接受,但我找到了一个不同的解决方案.

我认为问题是您按顺序指定了两个场景轮廓,然后将示例放在它们下面.使用"方案大纲"时,系统需要在指定其他方案之前使用示例块.因此,如果您只是在两个场景轮廓之间移动第一个示例块,则不应再发生错误.以下是您的功能文件应如下所示:
