Tests

[nathanweeks]

As functionality is added and updated, and newer pysam versions specified in requirements.txt, it would be useful to run a set of tests that can be run to validate updates.

Regarding implementation:

• The FastAPI docs recommend Requests + pytest. Alternatively, it may be possible to use curl against a running fasta-api instance, though there may be issues coordinating the startup (such as waiting until the fasta-api process is listening on port 8000) and validating the resulting JSON output (simple string comparison would probably be too brittle due to undefined ordering of name/value pairs in objects).
• Initially, could run tests against files in the data store; eventually, it may be preferable to add a small set of files in the supported formats to the fasta-api git repository.
• Initially these could be run manually (e.g., make test); eventually, they could also perhaps be automated to run via GitHub Actions workflow as part of a CI pipeline (e.g., run tests on pull request).
