What is a mock-server:

Mock server serves as a simulated or pseudo server that mimics authentic server behavior. They return controlled responses to requests, letting you design and create JSON API responses without writing a single line of code.

Let us assume that you are working as front-end developer in a large team that is tasked with building a web application that relies on a back-end API to fetch data. However, the back-end development is still in progress, and the API endpoints are not available yet. To avoid delays in front-end development, you decide to use a mock server in Postman.

Postman is a comprehensive API platform used by developers; this platform provides a set of tools that support API design, testing, documentation, mocking, and API Monitoring. It also simplifies each step of the API lifecycle and streamlines collaboration, enabling developers to create and use APIs more efficiently. Postman’s API client is the foundational tool of Postman, and it enables developers to easily explore, debug, and test APIs while also enabling them to define complex API requests for HTTP, REST, SOAP, GraphQL, and WebSockets.
