Specmatic JDBC Stub Demo
This project demonstrates how we can stub database dependencies with Specmatic JDBC stub.
Architectural overview
Context
In order to test our applications in isolation, we often need to isolate them from their dependencies such as databases. There are several options (in-memory databases, dockerizing your DB setup, etc.). However, there are limitations to each of these approaches.
- In-memory DBs usually cannot handle any DDL, DML syntax and data types that may be proprietary to your DB.
- While Dockerised DB setup may address the above issue to an extent, it requires some initial effort to achieve a DB setup that has parity with your production instance (Especially in legacy applications that lack proper automated DB deployment mechanisms).
Solution
Specmatic JDBC dependency is a completely wire-compatible setup that has none of the above limitations. It is able to seamlessly emulate a JDBC datasource so that your application thinks it is talking to the real database. This makes for a realist test setup that can be quickly spun up.
Private Beta
Specmatic JDBC Stub is currently in private beta. Please contact us at https://specmatic.in if you wish to try it out.
