StateBliss 1.0.4

Finite state machine with fluent syntax. i.e.

public class DefineAuthenticationState2 : StateDefinition<AuthenticationState>
{
public override void Define(IStateFromBuilder<AuthenticationState> builder)
{
builder.From(AuthenticationState.Unauthenticated).To(AuthenticationState.Authenticated)
.Changing(this, a => a.ChangingHandler1);

}

private void ChangingHandler2(StateChangeGuardInfo<AuthenticationState> changeinfo)
{
var data = changeinfo.DataAs<Dictionary<string, object>>();
data["key2"] = "ChangingHandler2";
}
}

public class BasicTests //xUnit
{

public enum AuthenticationState
{
Unauthenticated,
Authenticated
}

[Fact]
public void Tests()
{
// Arrange
StateMachineManager.Register(new [] { typeof(BasicTests).Assembly }); //Register at bootstrap of your application, i.e. Startup
var currentState = AuthenticationState.Unauthenticated;
var data = new Dictionary<string, object>();

// Act
var changeInfo = StateMachineManager.Trigger(currentState, AuthenticationState.Authenticated, data);

// Assert
Assert.True(changeInfo.StateChangedSucceeded);
Assert.Equal("ChangingHandler1", changeInfo.Data["key1"]);
}
}
