我已经配置了将构建操作设置为内容"的文件，并将其复制到输出目录到始终复制"，但是文件没有被复制到输出目录，根据System.Environment.CurrentDirectory就是

I've already configured the file with build action set to 'Content' and copy to output directory to 'Copy Always', but the file is not being copied to the output directory, which according to System.Environment.CurrentDirectory is

'{project_path} \ TestResults \ Pablo_COMPU 2009-11-26 15_01_23 \ Out'

This folder contains all the DLL dependencies of the project, but my text file is not there.

哪种是从单元测试访问文本文件的正确方法?

Which is the correct way to access a text file from a unit test?

推荐答案

您必须将DeploymentItem属性添加到测试类.使用此属性，您可以指定要复制到out目录中以进行测试运行的文件.

You have to add the DeploymentItem attribute to your test class. With this attribute you specify the files which are copied into the out directory for the test run.

例如:

[TestMethod]
[DeploymentItem(@"myfile.txt", "optionalOutFolder")]
public void MyTest()
{
    ...
}
