如何在运行单元测试时获取目录

Question

嗨,当我运行我的单元测试时,我想要获取我的项目正在运行的目录来检索文件.

假设我有一个名为MyProject的测试项目.测试我运行:

AppDomain.CurrentDomain.SetupInformation.ApplicationBase

我接受"C:\\Source\\MyProject.Test\\bin\\Debug".

这接近我所追求的.我不想要这个bin\\Debug部分.

任何人都知道我怎么能得到"C:\\Source\\MyProject.Test\\"？

Answer 1

我会做的不同.

我建议将该文件作为解决方案/项目的一部分.然后右键单击 - >属性 - >复制到输出=始终复制.

然后该文件将被复制到您的输出目录(例如C:\ Source\MyProject.Test\bin\Debug).

Answer 2

通常,您检索解决方案目录(或项目目录,具体取决于您的解决方案结构),如下所示:

string solution_dir = Path.GetDirectoryName( Path.GetDirectoryName(
    TestContext.CurrentContext.TestDirectory ) );

这将为您提供测试项目创建的"TestResults"文件夹的父目录.

Answer 3

Directory.GetParent(Directory.GetCurrentDirectory()).Parent.FullName;

这将为您提供所需的目录....

如

AppDomain.CurrentDomain.SetupInformation.ApplicationBase 

什么都没有

Directory.GetCurrentDirectory().

继续@ abhilash的评论.

这适用于我的EXE,DLL 以及在调试或发布模式下从不同的UnitTest项目进行测试时:

var dirName = Path.GetDirectoryName(Assembly.GetExecutingAssembly().Location.Replace("bin\\Debug", string.Empty));

{
    // Gets bin\Release or bin\Debug depending on mode
    string baseA = AppDomain.CurrentDomain.SetupInformation.ApplicationBase;
    Console.WriteLine(string.Format("Dir A:{0}", baseA));
    Assert.IsTrue(System.IO.Directory.Exists(baseA));

    // Gets bin\Release or bin\Debug depending on mode
    string baseB = AppDomain.CurrentDomain.BaseDirectory;
    Console.WriteLine(string.Format("Dir B:{0}", baseB));
    Assert.IsTrue(System.IO.Directory.Exists(baseB));

    // Returns empty string (or exception if you use .ToString()
    string baseC = (string)AppDomain.CurrentDomain.GetData("DataDirectory");
    Console.WriteLine(string.Format("Dir C:{0}", baseC));
    Assert.IsFalse(System.IO.Directory.Exists(baseC));


    // Move up two levels
    string baseD = System.IO.Directory.GetParent(baseA).Parent.FullName;
    Console.WriteLine(string.Format("Dir D:{0}", baseD));
    Assert.IsTrue(System.IO.Directory.Exists(baseD));


    // You need to set the Copy to Output Directory on each data file
    var appPathA = System.IO.Path.Combine(baseA, "App_Data");
    Console.WriteLine(string.Format("Dir A/App_Data:{0}", appPathA));
    // C:/solution/UnitTestProject/bin/Debug/App_Data
    Assert.IsTrue(System.IO.Directory.Exists(appPathA));

    // You can work with data files in the project directory's App_Data folder (or any other test data folder) 
    var appPathD = System.IO.Path.Combine(baseD, "App_Data");
    Console.WriteLine(string.Format("Dir D/App_Data:{0}", appPathD));
    // C:/solution/UnitTestProject/App_Data
    Assert.IsTrue(System.IO.Directory.Exists(appPathD));
}

Answer 6

我通常这样做,然后我只是添加"..\..\"到路径,以达到我想要的目录.

所以你能做的就是:

var path = AppDomain.CurrentDomain.SetupInformation.ApplicationBase + @"..\..\";
