Question

How can we repeatably and independently test code that shuffles a deck of card objects?

1) Use test cases with a fixed input and check if the output matches the expected result
2) Use random inputs and check if the output is a valid shuffle
3) Use a pre-defined order of cards and check if the output matches the expected order
4) Use a third-party library for testing the shuffle algorithm

Answer 1

To test code that shuffles a deck of card objects, you can use test cases with fixed input, random inputs, pre-defined order of cards, and third-party libraries for testing the shuffle algorithm.

Step-by-step explanation:

To test code that shuffles a deck of card objects, you can use a combination of test cases with fixed inputs, random inputs, pre-defined order of cards, and third-party libraries for testing the shuffle algorithm.

1) Using test cases with fixed input means that you provide a set of specific inputs and check if the output matches the expected result. For example, you can test if the code shuffles a deck of cards correctly when provided with a specific pre-shuffled deck.

2) Using random inputs means that you generate random decks of cards and check if the output is a valid shuffle. This helps test the code's ability to handle different combinations of cards.

3) Using a pre-defined order of cards means that you provide a specific order of cards and check if the output matches that order. This helps test the code's ability to preserve a desired order of cards during shuffling.

4) Using a third-party library for testing the shuffle algorithm can help ensure that the code follows established best practices and produces reliable results.
