如何使用Selenium和xUnit设置同步xUnit的值？

Question

我正在对Blazor应用程序进行硒测试，我想设置一个SfDropDownList的值。

我用SfDropDownList创建了一个空的Blazor项目，用Selenium和XUnit创建了一个测试项目。项目下载网址：https://www.syncfusion.com/downloads/support/forum/167910/ze/SYncfusionSelenium_b2ea0a0e

<SfDropDownList ID="MyDropdown" TValue="string" TItem="Games" Placeholder="Select a game" DataSource="@LocalData">
    <DropDownListFieldSettings Value="ID" Text="Text"></DropDownListFieldSettings>
</SfDropDownList>

@code {
    public class Games
    {
        public string ID { get; set; }
        public string Text { get; set; }
    }

    List<Games> LocalData = new List<Games> {
        new Games() { ID= "Game1", Text= "American Football" },
        new Games() { ID= "Game2", Text= "Badminton" },
        new Games() { ID= "Game3", Text= "Basketball" },
        new Games() { ID= "Game4", Text= "Cricket" },
        new Games() { ID= "Game5", Text= "Football" },
  };
}

这就是我如何设置/更改下拉列表的值:我通过ID访问SfDropDownList，并从我的类"Games“中设置'Text‘。我必须这样做2次，以确保它是正确的设置，这是我想出的最好的。

Thread.Sleep(TimeSpan.FromMilliseconds(250));
_driver.FindElement(By.Id("MyDropdown")).SendKeys("Basketball");


Thread.Sleep(TimeSpan.FromMilliseconds(250));
_driver.FindElement(By.Id("MyDropdown")).SendKeys("Basketball");

要运行Selenium：

http://localhost:5000上的

1. 启动服务器

- open VS -> select SyncfusionSelenium instead of IIS Server as a Launch option and hit     Ctrl+F5

- or open project folder -> open console a enter "dotnet watch run debug"

1. 打开测试资源管理器并运行/调试"Test1"

我非常感谢这里的一些帮助，因为我找不到如何为SfDropDownList做到这一点的例子。

我们可以在Blazor中借助bUnit测试用例实现您的需求。这也是处理blazor组件的建议方法，.Please引用下面的代码片段供您参考。

using System;   
using System.Collections.Generic;   
using System.Text;   
using Xunit;   
using Bunit;   
using Syncfusion.Blazor;   
using Syncfusion.Blazor.DropDowns;   
using Syncfusion.Blazor.Tests.Base;   
using static Bunit.ComponentParameterFactory;   
using Syncfusion.Blazor.Calendars;   
using System.Threading.Tasks;   
using AngleSharp.Css.Dom;   
using Syncfusion.Blazor.Inputs;   
using Microsoft.AspNetCore.Components.Web;   
using Microsoft.AspNetCore.Components;   
using System.Globalization;   
  
private List<Countries> GetDataItems()  
{  
    return new List<Countries>  
    {  
        new Countries() { Name = "Australia", Code = "AU" },  
        new Countries() { Name = "Bermuda", Code = "BM" },  
        new Countries() { Name = "Canada", Code = "CA" },  
        new Countries() { Name = "Cameroon", Code = "CM" },  
        new Countries() { Name = "Denmark", Code = "DK" },  
        new Countries() { Name = "France", Code = "FR" }  
    };  
}  
  
[Fact(DisplayName = "Value at dynamic changes")]  
public async Task DynamicValueBinding()  
{  
    var data = GetDataItems();  
    var dropdown = RenderComponent<SfDropDownList<string, Countries>>(parameters =>  
            parameters.Add(p => p.DataSource, data).AddChildContent<DropDownListFieldSettings>(field => field.Add(p => p.Text, "Name").Add(p => p.Value, "Code")));  
    dropdown.SetParametersAndRender(("Value", "AU"));  
    await Task.Delay(200);  
    var inputEle = dropdown.Find("input");  
    Assert.Equal(dropdown.Instance.Text, inputEle.GetAttribute("value"));  
    Assert.Equal(0, dropdown.Instance.Index);  
    dropdown.SetParametersAndRender(("Value", null));  
    Assert.Equal(dropdown.Instance.Text, inputEle.GetAttribute("value"));  
    Assert.Null(dropdown.Instance.Value);  
    Assert.Null(dropdown.Instance.Index);  
    dropdown.SetParametersAndRender(("Index", 3));  
    await Task.Delay(200);  
    inputEle = dropdown.Find("input");  
    Assert.Equal("CM", dropdown.Instance.Value);  
    Assert.Equal(3, dropdown.Instance.Index);  
    dropdown.SetParametersAndRender(("Index", null));  
    Assert.Null(dropdown.Instance.Value);  
    Assert.Null(dropdown.Instance.Index);  
}
