Question

我正在使用Specflow尝试BBD。运行功能文件时收到错误错误是：

Result Message: Microsoft.CSharp.RuntimeBinder.RuntimeBinderException : 'System.Dynamic.ExpandoObject' does not contain a definition for 'keyword'

错误在此方法中的某处：

 [Then(@"I should see the result for keyword")]
    public void ThenIShouldSeeTheResultForeyword(Table table)
    {
        dynamic tableDetail = table.CreateDynamicInstance();
        String key = tableDetail.keyword;
        if (currentDriver.FindElement(By.PartialLinkText(key)).Displayed == true)
            Console.WriteLine("Control Exist");
        else
            Console.WriteLine("Control not exist");
    }

我的功能文件实现是：

@SmokeTest
@Browser:Chrome
Scenario: Google Search for Execute Automation
    Given I have navigated to Google page
    Given I see the Google page fully loaded
    When I type search keyword as
    | Keyword     |      
    | Formula One |
    Then I should see the result for keyword
    | keyword     |       
    | Formula One |


My steps defincition file implementation is:

    using System;
    using System.Collections.Generic;
    using System.Linq;
    using System.Text;
    using System.Threading.Tasks;
    using SpecFlow.Assist.Dynamic;
    using OpenQA.Selenium;
    using System.Configuration;
    using TechTalk.SpecFlow;
    using Baseclass.Contrib.SpecFlow.Selenium.NUnit.Bindings;
    using TechTalk.SpecFlow.Assist;
    using SpecFlow.Assist;
    using SpecFlow;

    namespace SpecFlowFirst.Steps
    {
        [Binding]
        class GoogleSearchSteps
        {
            IWebDriver currentDriver = null;

            [Given(@"I have navigated to Google page")]
            public void GivenIhaveNavigatedToGooglePage()
            {
                Browser.Current.Navigate().GoToUrl(ConfigurationManager.AppSettings["seleniumBaseURL"]);
                currentDriver = Browser.Current;
            }

            [Given(@"I see the Google page fully loaded")]
            public void GivenISeeTheGooglePageFullyLoaded()
            {
                if (currentDriver.FindElement(By.Name("q")).Displayed == true)
                    Console.WriteLine("Page loaded fully");
                else
                    Console.WriteLine("Page failed to load");
            }

            [When(@"I type search keyword as")]
            public void WhenITypSsearchKeywordAs(Table table)
            {
                dynamic tableDetail = table.CreateDynamicInstance();
                currentDriver.FindElement(By.Name("q")).SendKeys(tableDetail.keyword);
            }

            [Then(@"I should see the result for keyword")]
            public void ThenIShouldSeeTheResultForeyword(Table table)
            {
                dynamic tableDetail = table.CreateDynamicInstance();
                String key = tableDetail.keyword;
                if (currentDriver.FindElement(By.PartialLinkText(key)).Displayed == true)
                    Console.WriteLine("Control Exist");
                else
                    Console.WriteLine("Control not exist");
            }
            }


    }

我不确定为什么在运行该功能时会抛出错误。解决方案构建没有错误。

感谢您的帮助，Riaz

Answer 1

简要地查看code for that method我认为它可能会“修复”该属性的情况，因此请尝试使用String key = tableDetail.Keyword

Answer 2

I rewrote Baseclass.Contrib.SpecFlow.Selenium.NUnit for 2.1 support.

新代码库，对nunit3的@ignore标签支持以及BrowserStack，SauceLabs，TestingBot等多种测试服务。以防您想要升级到2.1

Answer 3

以下是有问题的情景：

when

我只想指出：

您的Keyword语句的表格中包含then列（大写字母K），
您的keyword语句的表格中包含tableDetails.Keyword列（小写k）。

这意味着如果您同时更新keyword的两个用法（从Keyword到IDictionary<string, object>，反之亦然），其中一个将始终抛出。

调试建议

如果这对您不起作用，请记住host key in your manifest.yml实施IEnumerable<KeyValuePair<string, object>>和CreateDynamicInstance，这意味着您始终可以向控制台打印可用的密钥以便了解$filters = @("*a*","*b*") $data = @("c/a","c/b","c/a/d","e","a","e/f") $desiredResults = @("e","e/f") Write-Host "Filters" -ForegroundColor Yellow $filters Write-Host "Data" -ForegroundColor Yellow $data $results = @() foreach ($d in $data) { [bool] $skip = $false foreach ($filter in $filters) { if ($d -like $filter) { $skip = $true } } if ($skip -eq $false) { $results += $d } } Write-Host "Desired Results" -ForegroundColor Yellow $desiredResults Write-Host "Results" -ForegroundColor Yellow $results

实际创建的是什么

运行功能时BDD C＃错误不包含'keyword'的定义
