Output status of model immediately after it finishes running

[JCGoran]

The CI currently takes about an hour and a half to finish, but none of the results are shown until the CI actually finishes, making it slow to debug any problems. It would be nice to refactor the package so it outputs at least the outcomes immediately: statuses like "Passed", "Failed", and, in case of failure, which type of failure (at the build step, or the run step).
