What is your approach to test data management in automation?
- test data
- data management
- isolation
Answer it first, then compare. Nothing here is saved or scored.
Model answer
Strategies by maturity: (1) Hardcoded data in tests, simplest but fragile. (2) Factory functions that generate unique data per run (faker libraries). (3) API-based setup/teardown, create test data via API before tests, clean up after. (4) Database seeding, restore a known state before each test suite. (5) Isolated test environments per PR with their own database. Best practice: each test should create its own data and clean up, never depend on pre-existing state. Use unique identifiers (timestamps, UUIDs) to prevent collisions in parallel runs.
What interviewers listen for
- Test architecture instinctsYou can defend why your suite is shaped like a pyramid, a trophy, or a honeycomb.
- Locator disciplineYou rank selector strategies by stability and explain when to break the rule.
- Flaky test ownershipYou debug to a structural fix instead of retry-until-green.
- Parallelisation literacyYou know how your framework isolates state, fixtures, and database access across workers.
