Test full chain in multiple chunks and clean up input tests

[mhliu0001]

Previously, the tests only simulated one chunk. This PR adds tests for multiple chunks.

Also, this PR rewrites test_input.py to capture exceptions more elegantly.

I will add some more tests to increase the coverage.

Hi @mhliu0001, what is the status of this PR?

[mhliu0001]

Hi @HenningSE , I think this can be merged now if you want. My original plan was to add some tests with empty instructions, but for the moment this is not the priority.

[HenningSE]

Thanks for the PR @mhliu0001 . I re-enabled the single chunk full chain tests (more tests won't hurt us) and will merge this PR when the checks are successful. We can add more tests like you suggested in future PRs.
