Tools to e2e test compiled binaries in integrated dockerized environment?

Question

After searching for tools to do the test of user scenarios, grade e2e, of binaries fully installed in their environment (meaning containers... Docker), I found nothing that looks match my needs.

So it's no orchestration, which would be on top of it. It's also not the tool that you could install on a machine to do the tests. I think I'm searching for a framework to test if docker based images have to proper outputs.

Docker has no output? Yeah, that's my question. How to make it so? Is their already a framework that thought to every of that?

Inputs:

• Docker image
• case data (files)
• scenarios (scripts)

Outputs:

• return values
• files
• container (not deleted, just in case)

Or am I totally thinking it sideways?

It's NOT web, NOT api, NOT user interfaces.

How is the tool Giving output ? Is it printing to console? Or a file?. You can access docker outputs by the following methods.

1. If tool/SUT(service under test) is printing to console you can access the docker logs and get those data.

   docker logs -f

2. IF output is stored to a file say ./output.txt Access that file

   docker cp <target_path> <destination_path>

3. Create an API service or webserver in docker, Expose a docker port and access those files using the API service or url. THe below command let you access your docker service running on localhost:80 from h=your host system through localhost:8080.

   docker run -p 127.0.0.1:80:8080/tcp ubuntu bash

4. You can mount the docker to a host volume

   docker volume create logdata docker run -it --name volume1 --mount type=volume,source=<volumename>,target=<target> microsoft/windowsservercore powershell
