Prisma Mock

prisma-mock is an in-memory mocking library designed for unit testing applications that interact with Prisma ORM. It fully simulates the Prisma API, allowing developers to execute database-dependent unit tests rapidly without requiring an actual database connection or external dependencies. The current stable version is 1.1.0, with an active release cadence involving frequent patch and minor updates to support new Prisma versions and features. A key differentiator is its in-memory data storage, which ensures fast and reliable test execution. It offers optional integration with `jest-mock-extended` or `vitest-mock-extended` for enhanced mocking capabilities and provides dedicated entry points (`prisma-mock` vs. `prisma-mock/client`) to accommodate different Prisma client versions. The library also supports initializing the mock client with pre-filled data and includes methods like `$clear()` and `$setInternalState()` for robust state management across tests, making it a comprehensive tool for isolating database logic during testing.
