Unit testing Fluxtion

---

There are no special steps required to run event processors in a unit test or any other testing framework, they are normal java classes that can be used in any domain.

See the developer workflow section for an example of unit testing

class CommandExecutorTest {
    @Test
    public void testPermission(){
        var processor = Fluxtion.interpret(new CommandExecutor(new CommandAuthorizerNode()));
        processor.init();

        CommandAuthorizer commandAuthorizer = processor.getExportedService();
        commandAuthorizer.authorize(new CommandPermission("admin", "shutdown"));
        commandAuthorizer.authorize(new CommandPermission("admin", "listUser"));
        commandAuthorizer.authorize(new CommandPermission("Aslam", "listUser"));
        commandAuthorizer.authorize(new CommandPermission("Puck", "createMischief"));

        LongAdder longAdder = new LongAdder();
        processor.onEvent(new AdminCommand("admin", "shutdown", longAdder::increment));
        Assertions.assertEquals(1, longAdder.intValue());

        processor.onEvent(new AdminCommand("Aslam", "listUser", longAdder::increment));
        Assertions.assertEquals(2, longAdder.intValue());

        processor.onEvent(new AdminCommand("Puck", "createMischief", longAdder::increment));
        Assertions.assertEquals(3, longAdder.intValue());

        processor.onEvent(new AdminCommand("Aslam", "shutdown", longAdder::increment));
        Assertions.assertEquals(3, longAdder.intValue());

        commandAuthorizer.removeAuthorized(new CommandPermission("Puck", "createMischief"));
        processor.onEvent(new AdminCommand("Puck", "createMischief", longAdder::increment));
        Assertions.assertEquals(3, longAdder.intValue());
    }
