Q# What is considered good practice when implementing the model?

Group of answer choices

1. When implementing the model, we can assume that all our input will be valid, so we do not need to worry about using exceptions. Instead we rely on the controller to clean the input and only make valid requests.

2. Plan ahead which pieces of data will need to be seen by the view in order to make sure that, when implementing the model, that these variables remain public.

3. Think about all the operations you want your model to perform. Consider things you wish to make sure the model does not allow. Then make class diagrams or UML diagrams to reflect this structure. Once you have made a plan for how to create the model you can write your JUnit tests, and then begin coding.

4. To write JUnit tests for all parts of the model after the model code is complete.
