getting error on spring webflow junit

I am new to spring webflow and start writting unit test cases for the webflow and getting the following error.I am struggling to write the test case as its mix with decision state,action state view state and subflow I didn't find any suitable reference so far.I have tried so many possible ways and struggling to get the concept can you please help me understand what mistake I am doing

Error
