Selenium 框架使用 C# 关于断言语句

Question

I am trying to provide a confirmation message that the record has been updated successfully.

The HTML is:

<div class="hide">
    <div class="fullRow">
    <div class="notice success">
        The user record has been updated.
        <a href="#close" class="icon-remove"/>
    </div>

The C# code that I am using is:

Assert.IsTrue(UserUpdateAdmin.IsAt, "Fialed to Update");

The UserUpdateAdmin class contains the following:

public class UserUpdateAdmin
{
    public static bool IsAt
    {
        get
        {
            var h1 = Driver.Instance.FindElements(By.ClassName("notice.success"));
            if (h1.Count > 0)
                return true;
            return false;
        }

It is throwing an exception: An exception of type

'Microsoft.VisualStudio.TestTools.UnitTesting.AssertFailedException' occurred in Microsoft.VisualStudio.QualityTools.UnitTestFramework.dll but was not handled in user code

Additional information: Assert.IsTrue failed. Failed to Update

Answer 1

You are using By.ClassName() but it can't contain more than one class. You can get around this by using By.CssSelector() . I also simplified your code.

public static bool IsAt
{
    get
    {
        return (Driver.Instance.FindElements(By.CssSelector("div.notice.success")).Count > 0);
    }
}

NOTE: You have a typo in your error message, it should be "Failed to Update".

Recommendation: Always use {} s... even on a 1-liner if , see below. It prevents confusion, etc.

if (h1.Count > 0)
{
    return true;
}

Answer 2

If your class name contains space, finding by class name usually does not work. Try to use XPath instead:

var h1 = Driver.Instance.FindElements(By.XPath("//div[@class='notice success']"));
