Answer from AI
In QA practice and test automation, the following data structures are often used:
- Arrays and Lists (List, ArrayList) — for storing sequences of test data, steps, or results.
- Sets (Set) — for storing unique elements, such as unique identifiers or test scenarios.
- Dictionaries/Hash Tables (Map, HashMap) — for key-value mapping, such as test parameters and their values.
- Stack and Queue — for managing the order of test execution or event processing.
Example: in Java test automation, it is common to use List<String> to store a list of URLs to check, and Map<String, String> to store test configuration parameters.
