I am writing automated tests for my MBTA commuter rail schedule app. Does there exist a test database, the contents of which are known, to test against?
For example, I have a method that fetches alerts for a specified commuter rail line. I'd like to test the case in which alerts exist for the line, and also as the case in which no alerts exist for the line. Running on live data, I can't be sure what the result of the test ought to be, so I can't tell for sure if it produced the correct behavior.
