unit testing自定义ConfigurationElement和ConfigurationElementCollection

我创建了一个自定义ConfigurationElement和ConfigurationSection ，以便在启动时更轻松地设置一系列应用程序参数。 但是，我真的很想对这个逻辑进行unit testing。

ServiceConnection

 public class ServiceConnection : ConfigurationElement { [ConfigurationProperty("locationNumber", IsRequired = true)] public string LocationNumber { get { return (string) base["locationNumber"]; } set { base["locationNumber"] = value; } } [ConfigurationProperty("hostName", IsRequired = true)] public string HostName { get { return (string) base["hostName"]; } set { base["hostName"] = value; } } [ConfigurationProperty("port", IsRequired = true)] public int Port { get { return (int) base["port"]; } set { base["port"] = value; } } [ConfigurationProperty("environment", IsRequired = true)] public string Environment { get { return (string) base["environment"]; } set { base["environment"] = value.ToUpper(); } } internal string Key { get { return string.Format("{0}|{1}", LocationNumber, Environment); } } } 

ServiceConnection集合

 [ConfigurationCollection(typeof(ServiceConnection), AddItemName = "service", CollectionType = ConfigurationElementCollectionType.BasicMap)] public class ServiceConnectionCollection : ConfigurationElementCollection { protected override ConfigurationElement CreateNewElement() { return new ServiceConnection(); } protected override object GetElementKey(ConfigurationElement element) { return ((ServiceConnection) element).Key; } public ServiceConnection Get(string locationNumber, string environment = "PRODUCTION") { return (ServiceConnection) BaseGet(string.Format("{0}|{1}", locationNumber, environment)); } public ServiceConnection this[int index] { get { return (ServiceConnection)BaseGet(index); } set { if (BaseGet(index) != null) { BaseRemoveAt(index); } BaseAdd(index, value); } } } 

一些测试XML

在我的生产代码中，我使用ConfigurationManager来检索ServiceConnection但我不确定如何创建一个完全绕过管理器的测试。

我正在寻找一个ServiceConnection对象，并确保所有字段都与我在测试XML中设置的输入相匹配。 当用户无法填充一个或多个字段时，我还想测试function。

好吧，我最终只是简单地使用@CodeCaster建议并使用ConfigurationManager （如他的链接所示）。

我在下面发布了一个示例测试：

 [Test] public void ShouldProvideFullProductionServiceConnectionRecord() { //NOTE: Open ConfigTests.config in this project to see available ServiceConnection records //Arrange ExeConfigurationFileMap fileMap = new ExeConfigurationFileMap { ExeConfigFilename = "ConfigTests.config" }; Configuration config = ConfigurationManager.OpenMappedExeConfiguration(fileMap, ConfigurationUserLevel.None); ServiceConnectionSection section = config.GetSection("AutomationPressDataCollectionServiceConnections") as ServiceConnectionSection; //Act var productionSection = section.Connections.Get("0Q8"); //Assert Assert.AreEqual("0AB0", productionSection.LocationNumber); Assert.AreEqual("DEVSERVER", productionSection.HostName); Assert.AreEqual(1234, productionSection.Port); Assert.AreEqual("DEVELOPMENT", productionSection.Environment); } 

它需要您添加一个新的.Config文件并将其输出设置为Content并设置为Copy if Newer （它位于unit testing项目中）。 但它比没有覆盖更好。
