c# - 使用 Protractor 的 C# 单元测试中的无效操作异常

Question

我有一个像这样的简单测试类:

public class MyTest
{
    const string URL = "https://example.com/content/mypage.aspx";

    IWebDriver driver;
    NgWebDriver ngDriver;

    [SetUp]
    public void Setup()
    {
        driver = new ChromeDriver();
        driver.Manage().Timeouts().SetScriptTimeout(TimeSpan.FromSeconds(10));
        ngDriver = new NgWebDriver(driver);
    }

    [TearDown]
    public void Teardown()
    {
        ngDriver.Quit();
    }

    [Test]
    public void Basic()
    {
        ngDriver.Url = URL;

        Assert.IsTrue(ngDriver.FindElement(By.CssSelector("#my")).Displayed);
    }
}

这是 HTML 片段:

<kendo-button id="my" ng-click="myCtrl.doSomething()">Do Something</kendo-button>

我在 Assert.IsTrue 行收到以下错误:

javascript error: [ng:test] http://errors.angularjs.org/1.3.15/ng/test
JavaScript stack:

堆栈跟踪是:

   at Protractor.NgWebDriver.FindElement(By by) in c:\Users\Bruno\Projets\GitHub\bbaia\protractor-net\src\Protractor\NgWebDriver.cs:line 262

我只有 Protractor 和 Selenium WebDriver Nuget 包。是否还有其他我需要安装的东西，或者这实际上是代码问题？

Answer 1

您实际上并没有导航到 Assert 之前的 URL？

尝试-

[Test]
public void Basic()
{
   NgDriver.Navigate().GoToUrl(URL);
   Assert.IsTrue(ngDriver.FindElement(By.CssSelector("#my")).Displayed);
}
