.net core test fails but works on PC

[stephen_b]

Using .net Core 2.0

I have a project that has some tests. When the tests run on the pipeline I am getting a runtime error.

When I run the same command on my PC against the working copy the test run without error.

How can I troubleshoot this?

To reproduce a problem with Pipelines locally, you need to debug it inside the Docker container. You need to start the relevant Docker container on your machine, mount your source code in there, then run the commands from your build script. Our documentation has some example Docker commands on Linux that should pretty easy to adapt for Windows.

The most common issue is that Docker containers typically have a limited set of build tools installed, so that they are small to download and fast to start up. Your build may be using something commonly available on a regular desktop but not provided in the container.

If you can provide the actual error message here, we might be able to help a bit more.

Thanks for the response Matt.

The error I was getting was related to resource files. I suspect that for some reason, the file was not being embedded into the assembly when it was building. 

I refactored the code to remove the resource file alltogether.

Now I an getting another problem related to file IO testing.

That's another problem I need to debug .

I will look into running a Docker container locally to troubleshoot first.
