What types of collection data structures have I used in my projects?

In projects for testing and automation, I used various collection data structures depending on the task:

• Lists (List) — for storing ordered sets of elements, such as a list of test cases or results.
• Sets (Set) — for storing unique elements, such as unique identifiers or tags.
• Dictionaries (Map) — for storing key-value pairs, such as test parameters or configurations.

Example in Dart:

List<String> testCases = ['LoginTest', 'SignupTest', 'LogoutTest'];
Set<String> uniqueTags = {'smoke', 'regression', 'critical'};
Map<String, String> config = {'env': 'staging', 'browser': 'chrome'};

The choice of structure depends on the requirements for data storage and processing in tests.
