DeploymentItem在VS2010和VS2012中的行为方式不同

Question

I have a VS2010 solution that I'm trying to upgrade to VS2012.

I'm having a problem with the MSTest unit tests in VS2012. All of the tests include DeploymentItem attributes on the test class.

[TestClass]
[DeploymentItem(@"SubDir\SubDir2\models", "models")]
public class UnitTests
{ ... }

In 2010, it's correctly copying dependent files from the SolutionDirectory\\SubDir\\SubDir2\\models directory.

In 2012, it's attempting to copy from the directory where the tests are deployed SolutionDirectory\\UnitTests\\bin\\debug\\SubDir\\SubDir2\\models

I'm looking for a way to restore the old behavior.

Answer 1

如果在解决方案中创建测试设置文件，请在其中启用部署（默认情况下在测试设置中关闭部署）并在测试资源管理器中选择它（测试 - >测试设置 - >选择测试设置文件），然后它应该在不改变代码的情况下工作。

Answer 2

After installing vs2012 and .net 4.5, looks like the deploymentitemattribute is out of sync with where it moves the files and where the executable looks for the files during execution of tests.

Cheap workaround:

1. Leave the deploymentitemattribute path as-is
2. See where the file is being moved to
3. Change the test code to look in that location

Before this upgrade mstest was smart enough to find deployment items even if they were moved to a sub directory in the bin directory. Seems this is no longer the case.

So before the upgrade a line of your unit test code might look like this...

FileInfo fi = new FileInfo("temp.txt");

After the upgrade a line of your unit test code might look like this...

FileInfo fi = new FileInfo("\SubDir\SubDir2\models\temp.txt");
