如何为目录中的每个文件运行Visual Studio单元测试？

Question

I have a unit test that is currently set up to take inputs from a csv file defined using the DataSource attribute on the test. I'd like to change this so that instead of condensing several files into a csv, the unit test would run for each file in a directory. Is there a way to create the datasource dynamically so that it contains the list of filenames in the directory?

Answer 1

There was essentially no way to do what I was originally asking. So instead, I created the test like normal, specifying a CSV/TXT file to be used as input for the test method. However, I added a pre-build event to the test project that ran a PowerShell script which created the input file with the paths for all the files in the target directory. This worked flawlessly.
