After you have finished this exercise, you understand how you can write the required table level assertions when you are writing integration tests for code that updates the information of an existing row. You can finish this exercise by following these steps:
1. Open the UpdateTodoItemTest class that’s found from the com.cleantestautomation.assertjdb.todoitem package.
2. Write the table level assertion which ensures that the system under test doesn’t insert a new row into the todo_item table or delete a row from the todo_item table when the updated todo item isn’t found from the database. You have to add this assertion to the shouldNotInsertNewTodoItemsIntoDatabaseOrDeleteTodoItemsFromDatabase() method that’s found from the WhenUpdatedTodoItemIsNotFound class.
3. Write the table level assertion which ensures that the system under test doesn’t insert a new row into the todo_item table or delete a row from the todo_item table when the updated todo item is found from the database. You have to add this assertion to the shouldNotInsertNewTodoItemsIntoDatabaseOrDeleteTodoItemsFromDatabase() method that’s found from the WhenUpdatedTodoItemIsFound class.
4. Run the tests found from the UpdateTodoItemTest class and make sure that they pass.
