Prismock

Overview

Prismock is an innovative mock for PrismaClient that elevates the testing experience by reading your schema.prisma file and generating models dynamically. It allows developers to simulate Prisma's API with an in-memory solution that facilitates fast, isolated, and retry-able unit tests. This makes it an ideal tool for projects that require extensive testing across various environments such as MySQL, PostgreSQL, and MongoDB. The library's effectiveness stems not only from its design but also from its rigorous testing, where the results from the mock are carefully compared with actual query outputs from Prisma.

Using Prismock, developers can easily prototype their applications while enjoying an in-memory implementation of Prisma. It simplifies the setup for testing, providing a clear path to achieving reliable unit tests without the need for extensive database interactions. The utility is perfect for those who prioritize both performance and accuracy in their testing processes.

Features

• Schema-Based Model Generation: Automatically reads from your schema.prisma and generates models, ensuring accuracy and reducing setup time.
• In-Memory Storage: Stores data in memory for fast tests that are isolated and can be retried without dependency on external databases.
• Compatibility: Supports multiple database environments including MySQL, PostgreSQL, and MongoDB, making it versatile for various applications.
• Extensive Query Support: Offers support for a comprehensive range of model queries such as findUnique, create, delete, and more, covering most common use cases.
• Custom Client Path Usage: Allows for custom client paths with the createPrismock method, providing flexibility in integrating into existing applications.
• Additional Utility Functions: Includes getData and reset functions for edge-case scenarios requiring direct data management, although often unnecessary in standard use.
• Nested Queries Support: Facilitates complex operations by supporting nested queries like createMany, update, and connect, enhancing testing scenarios.
• Automatic Mocking Setup: Simplifies the mocking process with an easy setup, allowing automatic mocking of Prisma in your tests without extensive configuration.
