[英]C# var keyword confusion: Type 'object' does not contain a definition for… error
[英]BDD C# error when i run feature does not contain a definition for 'keyword'
我正在使用Specflow尝试BBD。 运行功能文件时出现错误。
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:
[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功能时会引发错误。 该解决方案的构建没有错误。

感谢您的帮助,里亚兹
我将Baseclass.Contrib.SpecFlow.Selenium.NUnit重写为2.1支持。
新的代码库,对nunit3的@ignore标记支持以及一些测试服务,例如BrowserStack,SauceLabs,TestingBot。 万一你想升级到2.1
这是有问题的方案:
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 |
我只想指出:
when
语句具有一个包含Keyword
列(大写字母K)的表, then
语句就有一个带有keyword
列的表(小写字母k)。 这意味着,如果您同时更新tableDetails.Keyword
两种用法(从keyword
到Keyword
,反之亦然),则其中之一将始终抛出。
如果这对您不起作用,请记住ExpandoObject
实现IDictionary<string, object>
和IEnumerable<KeyValuePair<string, object>>
,这意味着您始终可以在控制台上打印可用键以了解实际的内容由CreateDynamicInstance
创建
