C# Assert.AreEqual问题，验证错误为c

我的Assert.AreEqual有问题。我的代码正在验证我预期的验证错误是否正确。但是在我的Assert.AreEqual和validationError中抛出了一个异常

如果继续，然后单击“继续”按钮而不在任何字段中输入任何信息，则可以看到验证错误

WebDriverWait wait = new WebDriverWait(webDriver, TimeSpan.FromSeconds(10));
IWebElement error = wait.Until(ExpectedConditions.ElementExists(By.XPath("//div[contains(@class, 'validation-error')]")));

Assert.AreEqual("Excpected validation error text", validationError.TextTrim());

namespace Exercise1
{
    class RunPath
    {

            static void Main()
            {

                IWebDriver webDriver = new ChromeDriver();
                webDriver.Navigate().GoToUrl("https://energy.gocompare.com/gas-electricity");
                webDriver.Manage().Window.Maximize();



            String title = webDriver.Title;

            String expectedTitle = "Utilities from Go Compare";
            if (title.Contains(expectedTitle))
            {
                Console.WriteLine("Tile is matching with expected value");
            }
            else
            {
                throw new Exception("Title does not match");
            }


            String someText = webDriver.FindElement(By.XPath("//h1[@class='c-header__heading']")).Text;

            String expectedHeader = "Switch today and save on your energy bills";
            if (someText.Contains(expectedHeader))
            {

                Console.WriteLine("title matches");
            }
            else
            {

                throw new Exception("Title does not match");
            }


            webDriver.FindElement(By.XPath(".//button[@type = 'submit']")).Click();

            WebDriverWait wait = new WebDriverWait(webDriver, TimeSpan.FromSeconds(10));
            IWebElement country = wait.Until(ExpectedConditions.ElementExists(By.XPath("//div[contains(@class, 'validation-error')]")));

            Assert.AreEqual("Expected validation error text", validationError.TextTrim());

与此相反：

Assert.AreEqual("Excpected validation error text", validationError.TextTrim());  

试试这个：

IWebElement country = wait.Until(ExpectedConditions.ElementExists(By.XPath("//div[contains(@class, 'validation-error')]")));
Assert.AreEqual("Please provide your postcode, as different regions have different fuel prices.", country.Text.Trim());  

更新：

如果你想在没有Nunit的情况下完成它。根据我们的讨论

您可以按照以下步骤操作：

IWebElement country = wait.Until(ExpectedConditions.ElementExists(By.XPath("//div[contains(@class, 'validation-error')]")));  
String errorMsg = country.Text();
try{ 
if(errorMsg.Trim().Contains("Please provide your postcode, as different regions have different fuel prices."))
Console.WriteLine("Yes matched");
}

catch(Exception ex)
{
Console.WriteLine("Error msg did not match with the exact error msg");
}

这是什么错误？给出stacktrace，错误消息etcI get名称“Assert”在当前上下文中不存在，并且IWebElement不包含“TextTrim”@L.Dockster的定义：更新了整个答案，请立即检查。Assert and wait在当前上下文中不存在打印此行：Console.WriteLinecountry.Text；问题是=等待和断言用红色下划线
