Test script for the Trello Integration
To test properly, setup a new board with at least one list and pass the ID as environment variable TEST_BOARD.

This test suite runs both unit tests and integration tests

 * Integration tests are run if API_KEY and API_TOKEN are provided
 * Integration tests can save the output of individual calls to ./test_data if GEN_TEST_DATA
 * Unit tests use data from the static JSON test data (appended with _unit) in the ./test_data directory.

Envvars:
    API_TOKEN: If configured, runs integration tests.
    API_KEY: Key assocaited with API token
    TEST_BOARD: ID of Trello board to use as testing ground
    GEN_TEST_DATA: If set, copies the raw output* of the API queries into ./test_data
