[improvement] Run tests automatically for pull requests

[nolbuzanis]

Is your feature request related to a problem? Please describe. Not really just good practice. There are lots of tests, but not an easy way to tell if new commits break anything.

Describe the solution you'd like Could add valid twitter credentials for a test account to the CI pipeline for running tests. Could also change most of these tests to mock the network request if that is not the main function/system under test.
