当运行起来我的测试失败，但单独通过 [英] My test fail when run together, but pass individually

问题描述

快速的问题......当我写在Visual Studio的测试，我检查它的工作原理是节能，建筑，然后在NUnit的运行测试（右键单击测试，然后运行）。

Quick question for you... When I write a test in Visual Studio, I check that it works by saving, building and then running the test it in Nunit (right click on the test then run).

测试工作耶...
，所以我继续......

The test works yay... so I Move on...

现在我已经写了另外一个测试和它的作品，因为我已经保存并测试它上面一样。但是，他们没有当他们一起运行工作。

Now I have written another test and it works as I have saved and tested it like above. But, they dont work when they are run together.

下面是我当作为个体时一起运行运行，但不能在该工作的两个测试：

Here are my two tests that work when run as individuals but fail when run together:

using System;
using NUnit.Framework;
using OpenQA.Selenium.Support.UI;
using OpenQA.Selenium;

namespace Fixtures.Users.Page1
{
    [TestFixture]
    public class AdminNavigateToPage1 : SeleniumTestBase
    {
        [Test]
        public void AdminNavigateToPage1()
        {
            NavigateTo<LogonPage>().LogonAsCustomerAdministrator();
            NavigateTo<Page1>();
            var headerelement = Driver.FindElement(By.ClassName("header"));

            Assert.That(headerelement.Text, Is.EqualTo("Page Title"));
            Assert.That(Driver.Url, Is.EqualTo("http://localhost/Page Title"));
        }

        [Test]
        public void AdminNavigateToPage1ViaMenu()
        {
            NavigateTo<LogonPage>().LogonAsCustomerAdministrator();
            Driver.FindElement(By.Id("menuitem1")).Click();
            Driver.FindElement(By.Id("submenuitem4")).Click();
            var headerelement = Driver.FindElement(By.ClassName("header"));

            Assert.That(headerelement.Text, Is.EqualTo("Page Title"));
            Assert.That(Driver.Url, Is.EqualTo("http://localhost/Page Title"));
        }
    }
}

在第二次测试失败，因为他们已经一起跑

When the second test fails because they have been run together

NUnit的呈现这样的：

Sse.Bec.Web.Tests.Fixtures.ManageSitesAndUsers.ChangeOfPremises.AdminNavigateToChangeOfPremises.AdminNavigateToPageChangeOfPremisesViaMenu：
OpenQA.Selenium.NoSuchElementException：元素无法找到

Sse.Bec.Web.Tests.Fixtures.ManageSitesAndUsers.ChangeOfPremises.AdminNavigateToChangeOfPremises.AdminNavigateToPageChangeOfPremisesViaMenu: OpenQA.Selenium.NoSuchElementException : The element could not be found

这行被突出显示：

var headerelement = Driver.FindElement(By.ClassName("header"));

有谁知道为什么当运行起来我的代码会失败，但单独运行时通过？

Does anyone know why my code fails when run together, but passes when run alone?

任何答案，将不胜感激！

Any answer would be greatly appreciated!

推荐答案

两件事可以尝试

1. 把下面的两条线之间的断点。而看到这页你当第二线打在



2. 通过介绍Thread.sleep代码

1. put the break point between the following two lines. And see which page are you in when the second line is hit

2. Introduce a slight delay between these two lines via Thread.Sleep

Driver.FindElement（By.Id（submenuitem4））点击（）;
VAR headerelement = Driver.FindElement（By.ClassName（头））;

Driver.FindElement(By.Id("submenuitem4")).Click(); var headerelement = Driver.FindElement(By.ClassName("header"));
