如何从HostType("Moles")测试中读取UnitTest项目的App.Config

Question

我有以下测试:

[TestClass]
public class GeneralTest
{
    [TestMethod]
    public void VerifyAppDomainHasConfigurationSettings()
    {
        string value = ConfigurationManager.AppSettings["TestValue"];
        Assert.IsFalse(String.IsNullOrEmpty(value), "No App.Config found.");
    }

    [TestMethod]
    [HostType("Moles")]
    public void VerifyAppDomainHasConfigurationSettingsMoles()
    {
        string value = ConfigurationManager.AppSettings["TestValue"];
        Assert.IsFalse(String.IsNullOrEmpty(value), "No App.Config found.");
    }
}

它们之间的唯一区别是[HostType("Moles")].但第一次传球,第二次传球失败.如何从第二次测试中读取App.config？

或者我可以在其他地方添加另一个配置文件？

Answer 1

假设您正在尝试访问appSettings中的值,那么只需在测试开始时添加配置即可.就像是:

ConfigurationManager.AppSettings["Key"] = "Value";

然后,当您的测试尝试读取AppSettings"Key"时,将返回"Value".

Answer 2

您只需将"App.Config"文件添加到单元测试项目中.它会自动读取.

同时,作为解决方法,您可以尝试将配置设置添加到Microsoft.Moles.VsHost.x86.exe.config

    [ClassInitialize]
    public static void MyClassInitialize(TestContext testContext)
    {
        System.Configuration.Moles.MConfigurationManager.GetSectionString =
            (string configurationName) =>
                {
                    ExeConfigurationFileMap fileMap = new ExeConfigurationFileMap();
                    Assembly assembly = Assembly.GetExecutingAssembly();
                    fileMap.ExeConfigFilename = assembly.Location + ".config";
                    Configuration config = ConfigurationManager.OpenMappedExeConfiguration(fileMap, ConfigurationUserLevel.None);
                    object section = config.GetSection(configurationName);
                    if (section is DefaultSection)
                    {
                        ConfigurationSection configurationSection = (ConfigurationSection) section;
                        Type sectionType = Type.GetType(configurationSection.SectionInformation.Type);
                        if (sectionType != null)
                        {
                            IConfigurationSectionHandler sectionHandler =
                                (IConfigurationSectionHandler)AppDomain.CurrentDomain.CreateInstanceAndUnwrap(sectionType.Assembly.FullName, sectionType.FullName);
                            section = 
                                sectionHandler.Create(
                                    configurationSection.SectionInformation.GetParentSection(), 
                                    null,
                                    XElement.Parse(configurationSection.SectionInformation.GetRawXml()).ToXmlNode());
                        }
                    }

                    return section;
                };
    }
