关于c#:单元测试自定义ConfigurationElement&

Unit Testing custom ConfigurationElement & ConfigurationElementCollection

我创建了一个自定义的ConfigurationElementConfigurationSection,以便在启动时更容易设置一系列应用程序参数。不过,我真的想对这个逻辑进行单元测试。

一些测试XML

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

我希望检索一个ServiceConnection对象,并确保所有字段与我在测试XML中设置的输入相匹配。我还想在用户未能填充一个或多个字段时测试功能。


好吧,我最终只是按照@codecaster的建议,使用ConfigurationManager(正如他在这里的链接所建议的那样)。

我在下面发布了一个样本测试:

[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);
}

它要求您添加一个新的.Config文件,并将其输出设置为Content并设置为Copy if Newer(它在一个单元测试项目中)。但总比完全没有覆盖要好。
