Strategies: fresh create-per-test, factories/fixtures, subset anonymized prod, synthetic data. Avoid shared mutable leftovers.
Lab: always use unique subjects (timestamps) so search assertions don’t collide.
Example / notes
import time
subject = f"vpn-{time.time_ns()}"
# create + search for subject — isolation without shared fixturesPractice in Lab: /lab/app/tickets/new/
