With test data — were they generated manually before refactoring?

Before refactoring, test data was often created manually, which could be time-consuming and prone to human error. After refactoring, automatic generation of test data using scripts or special libraries is usually implemented, which increases testing efficiency and quality.

For example, to generate test users, you can use the Faker library:

from faker import Faker
fake = Faker()

user = {
    'name': fake.name(),
    'email': fake.email(),
    'address': fake.address()
}
print(user)

This approach allows for quickly creating diverse and realistic data for tests.
