配置.单元测试中的管理器

我已经读了一些关于这个问题的很好的问题和答案例如不能在单元测试项目中使用ConfigurationManager

和如何模拟ConfigurationManager。AppSettings with moq

目前，我在单元测试中使用的解决方案是为单元测试项目建议一个App.config文件。它工作得很好。

我的目标是动态加载插件(*.dll)到我的c#项目。

这里是我的原始App.config

<?xml version="1.0"?>
<configuration>
  <configSections>
    <sectionGroup name="applicationSettings" type="System.Configuration.ApplicationSettingsGroup, System, Version=4.0.0.0, Culture=neutral, PublicFormattedKeyToken=b77a5c561934e089">

    </sectionGroup>
   <section name="CalibrationToolsSection" type="sec.Calibration.Configuration.CalibrationToolsSection,sec" />
  </configSections>
  <CalibrationToolsSection>
    <!-- This section contains the calibration tools' loading-enabling options, and versioning parameters as follows:
         toolname - the calibration tool's name as returned by GetName() in ICalibrationPlugin (for static tool) or as appears in the records (for auto-gen tool)
         isvisible - if set to "false" the tool will not be loaded. Deafult value: true
         version - if set to "false" the tool will not be loaded. Deafult value: true   /-->

我看到你可以动态创建集合，例如

ConfigurationManager.AppSettings["mykey"] = "myvalue";

现在我正在使用这样的类使用System.Configuration;

namespace Manager.Calibration.Configuration
{
    public class CalibrationToolsSection : ConfigurationSection
    {
        public static readonly string CALIBRATION_SECTION_NAME = "CalibrationToolsSection";
        [ConfigurationProperty("IpuToolCalibrations")]
        public IpuToolCalibrationCollection IpuToolCalibrations
        {
            get
            {
                return ((IpuToolCalibrationCollection)this["IpuToolCalibrations"]);
            }
            set
            {
                this["IpuToolCalibrations"] = value;
            }
        }
    }
}

和

public class IpuToolCalibrationCollection : ConfigurationElementCollection
    {
        public IpuToolCalibration this[int index]
        {
            get { return base.BaseGet(index) as IpuToolCalibration; }
            set
            {
                if (base.BaseGet(index) != null)
                {
                    base.BaseRemoveAt(index);
                }
                this.BaseAdd(index, value);
            }
        }
        protected override ConfigurationElement CreateNewElement()
        {
            return new IpuToolCalibration();
        }
        protected override object GetElementKey(ConfigurationElement element)
        {
            return ((IpuToolCalibration)element).Ipu;
        }
    }

等等

public class IpuToolCalibration : ConfigurationElement
    {
        public static readonly string IPU_TOOL_CALIBRATION_SECTION_NAME = "IpuToolCalibration";
        [ConfigurationProperty("ipu", IsRequired = true)]
        public string Ipu
        {
            get { return (string)this["ipu"]; }
            set { this["ipu"] = value; }
        }
        [ConfigurationProperty("CalibrationToolsLoadingSettings")]
        public ToolSettingElementCollection ToolsLoadingSettingsCollection
        {
            get
            {
                return ((ToolSettingElementCollection)this["CalibrationToolsLoadingSettings"]);
            }
            set
            {
                this["CalibrationToolsLoadingSettings"] = value;
            }
        }

        [ConfigurationProperty("PalAteConnectivitySettings")]
        public FilterAteConnectivityElementCollection PalAteConnectivityCollection
        {
            get
            {
                return ((FilterAteConnectivityElementCollection)this["PalAteConnectivitySettings"]);
            }
            set
            {
                this["PalAteConnectivitySettings"] = value;
            }
        }
    }
}

谁能解释我如何从代码中创建这些，因为它们都是没有构造函数的静态类，我该如何模拟它们，我使用NSubstitute。例如，如果我想加载部分插件而不是全部?

public class FileReaderService : IFileReaderService
{
    public string GetFileAsString(string fileName)
    {
        if(!File.Exists(fileName))
            throw new ArgumentException("File Path does not exist.");
        return File.ReadAllText(fileName);
    }
}
public interface IFileReaderService
{
    string GetFileAsString(string fileName);
}
