This video revisits the user storage FSM example and demonstrates how to test FSM actors. It emphasizes the importance of testing actors via messaging and introduces the test FSM ref for accessing internal states. The video provides detailed test cases to ensure FSM logic correctness, covering state transitions between connected and disconnected states. It concludes with a reminder to add more tests for business logic and a preview of testing multi-node setups in the next video.

What is the recommended way to test FSM actors?

• Via messaging and test probes

• Using a graphical user interface

• Using direct method calls

• By modifying the internal state directly

In the FSM actor logic, what happens when a connect message is received in the disconnected state?

• The FSM remains in the disconnected state

• The FSM resets to its initial state

• The FSM transitions to the connected state

• The FSM transitions to an error state

What is the purpose of the Test FSM Ref in FSM testing?

• To allow access to the internal state of the FSM

• To simulate network conditions

• To automatically generate test cases

• To provide a graphical interface for testing

Which state does the FSM transition to upon receiving a disconnect message in the connected state?

• It transitions to an error state

• It transitions to the disconnected state

• It transitions to a paused state

• It remains in the connected state

What should be verified to ensure FSM logic correctness?

• The state transitions and data integrity

• The user interface design

• The internal code structure

• The graphical representation of the FSM
