如何在单元测试用例调试时读取 Web.Config 文件? [英] How to read Web.Config file while Unit Test Case Debugging?

问题描述

我正在尝试从我的配置文件中获取数据(URL)

I am trying to fetch data(URL) from my configuration file

即:

<AppSettings>
<add key="configurationUrl" value="http://xx.xx.xx.xx:XXXX/configuration service/configurations"/>

使用以下代码

 reqClient.BaseAddress = System.Configuration.ConfigurationManager.AppSettings["configurationUrl"].ToString();

当我尝试调试它时一切正常，但是当我调试调用上面相同代码的单元测试用例时，主要问题出现了，而不是在 APPSettings 的 AllKeys 中显示configurationUrl"，而是显示TestProjectRetargetTo35Allowed".我还在测试用例项目中添加了 web.config 文件.

Its all working good when I am trying to debug it, but the major problem comes when I debug a unit test case calling the same code above, instead of Showing "configurationUrl" in the AllKeys of APPSettings its showing "TestProjectRetargetTo35Allowed". I have also added the web.config file in the testcase project.

任何帮助将不胜感激谢谢.

Any assistance will be appreciated Thank You.

推荐答案

我建议你创建一些抽象层来摆脱对 ConfigurationManager 的依赖.例如:

I suggest you create some abstraction layer to get rid of the dependency to ConfigurationManager. For example:

public interface IConfigurationReader
{
    string GetAppSetting(string key);    
}

public class ConfigurationReader : IConfigurationReader
{
    public string GetAppSetting(string key)
    {
        return ConfigurationManager.AppSettings[key].ToString();
    }
}

然后你可以在你的单元测试中模拟这个接口.

Then you could mock this interface in your unit test.
