Use GitHub Actions for Rails CI with Postgres

Writing tests alongside your software is strongly recommended. It helps you protect against bugs, reduces the fear of scary deploys, and can even help you develop better software.The Ruby and Rails community have always had a strong focus on testing. Typically that means having some sort of “continuous integration” system constantly running your test suite.There’s a bunch of good choices, but recently GitHub launched Actions (in beta), which lets you run arbitrary workflows, including tests, after certain things happen within your git repository.
