Does this skill require a specific test runner?

The patterns are optimized for Jest but the logic for environment setup and Prisma transactions can be adapted for other runners like Vitest or Mocha.

How does it manage test data between runs?

It implements a global setup that resets migrations and an after-each hook that uses TRUNCATE to clear tables, ensuring total isolation between individual tests.

Can I test complex database transactions?

Yes, it includes specific patterns for testing atomic operations, including verifying that data rolls back correctly when a step in a transaction fails.

Is this suitable for testing large schemas?

Absolutely. The TRUNCATE strategy is designed to be much faster than re-running migrations between every test, making it ideal for large PostgreSQL schemas.
