37.8. Exercises

1.	Look at the code for ActionFixture, which is quite short. Follow through the code to see what happens when an enter action is carried out.
2.	What happens if the corresponding method in the actor doesn't exist?
3.	What happens if the actor is not yet start ed?
4.	Note how ActionFixture calls the action methods, using reflection. Consider how you would subclass ActionFixture to provide other action methods, without changing ActionFixture itself.
5.	Look at the code for ColumnFixture and note how the method bind() is called from doRows() with the header row. Note how a TypeAdapter is created for each column of the header row and is reused for each test row.
