Fixing the TestsFailure error

Issue descriptionIssue description

When building a Docker image, you see this error during testing:

TestsFailure:It is not possible to start the docker container for testing.
Make sure that the requirements from the documentation are satisfied.

SolutionSolution

Correctness tests ensure that the project operates properly on the Docker image. The possible errors include:

1. The image is intended for launching a service, e.g., a web application, than a launch in Jupyter.

2. The error occurs because there is no jupyter user in Docker. You can install it using this command:

   RUN useradd -ms /bin/bash --uid 1000 jupyter
