如何设置一个Syncfusion SfDropDownList与硒和xUnit的值?

Question

我正在做一个Blazor web应用程序的Selenium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" },
};
}

这就是我如何设法设置/改变下拉列表的值: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，以确保正确设置，这是目前为止我想到的最好的。

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

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

运行Selenium:

1. 在http://localhost:5000启动服务器

   • open VS ->选择SyncfusionSelenium而不是IIS Server作为启动选项，并按Ctrl+F5

   • 或打开项目文件夹->打开控制台，输入"dotnet watch run ">

2. 打开测试资源管理器并运行/debug "Test1">

我非常感谢您的帮助，因为我找不到SfDropDownList的示例。

我们可以借助Blazor中的bUnit测试用例实现您的要求。这也是处理blazor组件的建议方法。请参考以下代码片段作为参考。

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);  
}
