Middleware acts as an intermediary between two different computer applications. A good example is software that is leased for the PlayStation 2 that does some of the work for the game developer, like providing a game engine. So they they are providing help to Group A so they can deliver to Group C. Middleware is software that connects two otherwise separate applications. Middleware is sometimes called "plumbing" because it connects two sides of an application and passes data between them. For example, Oracle's SQL*Net connect clients to the database server. Oracle's Gateways connect different types of databases (for example Oracle to SQL Server or DB2)

To test middleware, you can employ unit tests to verify its individual components and integration tests to ensure it interacts correctly with other parts of the application. Mocking dependencies is crucial for isolating the middleware during testing. Additionally, you can use functional tests to assess the middleware's behavior in a real-world scenario, ensuring it processes requests and responses as expected. Tools like Postman or automated testing frameworks can facilitate these testing processes.
