17 Questions
Why do refactoring steps need to be relatively small?
To reduce the risk of making accidental changes to functionality
In the context of refactoring, what is the purpose of extracting a function or method?
To prepare for moving code between classes
When referring to the extraction of variables, what should be considered regarding performance?
Considering potential performance issues
What is the primary reason for turning a complex expression into a reusable variable?
To improve code readability and potentially performance
Which technique helps in breaking up large monolithic functions during refactoring?
Extracting functions or methods
What makes regression testing important in the context of refactoring?
To check for accidental changes in functionality
What is the purpose of moving a method from one class to another?
To improve modularity and maintainability
What is the purpose of the 'k_future_mapping' function in the given code snippet?
To create a dictionary mapping current states to their respective next states with k-future information.
When moving a field to another class, what should be considered?
Placing the field where methods that use it are located
What data structure is used to store future state mappings in the 'k_future_mapping' function after applying the 'Extract Variable' refactoring?
Set
What does combining multiple functions into a class help improve?
Modularity, maintainability, and sustainability
In the 'k_future_mapping' function, what does the 'get_k_future' function do?
Calculates the k-future state for a given state in an FSM.
Why should automated refactoring be used with caution?
To avoid introducing new bugs or issues
After applying the 'Rename Variable' refactoring, what is the major advantage gained in terms of variable naming?
Improved readability and consistency in representing future state information.
What is the significance of using 'frozenset' in storing future state mappings in the 'k_future_mapping' function?
Ensures immutability and uniqueness of future state collections.
Which design principle is violated when methods are not moved to the classes where they belong?
Single Responsibility Principle
How does combining functions into a class impact code organization?
Improves code organization and readability
