Testing the State Machine

[tylerferrara]

Create python test cases for the state_machine package. We look to test the transitions between each state and assure they are as expected. Once implemented, we can add them to Travis CI to guard it's functionality.

• [x] Create a python test file in state_machine
• [x] Add a Makefile to state_machine invoking tests
• [x] Invoke this local Make Target to a project-wide make target
• [x] Run these tests in Travis CI #19

Each state will be published, as an enum, to the topic: \robots_state The full list of state/enum pairs will be found in the ROS params: state_enums

@AshayAswale I'm looking to test this state machine, so I need to know which transitions I should expect (and their respective enums).

• [x] Test cases, in the following, or similar format

  TEST_1 - "state-name" enum -> "state-name" enum -> "state-name" enum
  TEST_1 - "state-name" enum -> "state-name" enum
  ...

• [x] Specify what launch file (or ros nodes) need to be running before starting your state machine.

• [x] The exact command(s) to start the state machine

Thank you 🙌
