create a mil test for a state machine in matlab

To create a unit test for a state machine in MATLAB, you can follow these steps:

1. Define the inputs and expected outputs for each test case.
2. Instantiate the state machine object and set its initial state.
3. Call the methods of the state machine to execute the desired transitions.
4. Verify that the output matches the expected output for each test case.

Here's an example of how to create a unit test for a state machine with three states (A, B, C) and two events (X, Y):

main.m
classdef StateMachineTest < matlab.unittest.TestCase

    methods (Test)

        function testTransitionAtoB(testCase)
            sm = StateMachine();
            sm.setCurrentState('A');
            sm.handleEvent('X');
            expectedState = 'B';
            actualState = sm.getCurrentState();
            testCase.verifyEqual(actualState, expectedState);
        end

        function testTransitionBtoC(testCase)
            sm = StateMachine();
            sm.setCurrentState('B');
            sm.handleEvent('Y');
            expectedState = 'C';
            actualState = sm.getCurrentState();
            testCase.verifyEqual(actualState, expectedState);
        end

        % More test cases here...

    end

In this example, we define two test cases: one that tests the transition from state A to state B, and another that tests the transition from state B to state C.

For each test case, we instantiate a new StateMachine object and set its initial state to the starting state of the transition we want to test. We then call the handleEvent method of the state machine to execute the transition.

After the transition has been executed, we verify that the current state of the state machine matches the expected state for the test case, using the verifyEqual method of the matlab.unittest.TestCase class.

This approach allows us to define a number of test cases that cover all possible transitions in the state machine, ensuring that the state machine behaves as expected under all possible conditions.
