What types of collections have you used in your projects?

In QA and test automation projects, various types of collections are often used for storing and processing data:

• Lists — ordered mutable collections, convenient for storing sequences of elements, such as a list of test cases.
• Sets — unordered collections of unique elements, useful for removing duplicates or checking intersections.
• Dictionaries — collections of key-value pairs, often used for storing test parameters or results with quick access by key.
• Tuples — immutable sequences, used for storing fixed sets of data.

Example in Python:

# List of test cases
test_cases = ['test_login', 'test_logout', 'test_signup']

# Set of unique errors
errors = {'404 Not Found', '500 Internal Server Error'}

# Dictionary with test results
results = {'test_login': 'passed', 'test_logout': 'failed'}

# Tuple with parameters
params = ('chrome', 'windows', '1080p')
