DeploymentItemAttribute不起作用（正确）

Question

I have a Unit-TestClass. To test some functions for who i need database-access, i define the DeploymentItemAttribute at the head of the class directly after the TestClassAttribute.

For some reasons, running the Testclass shows very different beheaivor depending on if i run all the test of my TestProject or Testing only this units by pressing STRG+R, T.

By using CTRL+R, T, all tests of the class will succeed. By running all the tests of the testproject, they will fail because they can't find the file. By right-clicking on the Testclass in the solution-explorer and click "Run Unit-Tests", they will also fail.

I configured the file correctly. It will "always copy". More strangely, switching the deployment-flag in the testconfigurations will also invert the results.

Answer 1

Relying on my memory I can tell that by using CTRL+R, T you invoke default Microsoft's test runner, which deals with DeploymentItemAttribute as one would expect.
But when you say:

By running all the tests of the testproject, they will fail because they can't find the file. By right-clicking on the Testclass in the solution-explorer and click "Run Unit-Tests", they will also fail.

I'm more then sure that these commands are provided by ReSharper , hence tests are run using ReSharper's test runner, which in the past had issues with this attribute .

As for the solutions to this problem there are some mentioned here and here , but they might depend on the version of ReSharper so you might want to google it up for your specific version.
