Welcome to our Postman series. In this comprehensive tutorial series, we will embark on a journey to explore the ins and outs of Postman, a powerful tool that has become an indispensable companion for developers, testers, and API enthusiasts worldwide.

We will demystify the fundamentals of API communication, guide you through the user-friendly interface of Postman, and showcase how to create and manage collections to organize your API requests efficiently. We’ll delve into the intricacies of handling authentication, manipulating requests using variables, automating workflows with scripts, and a lot more!

What is Postman?

Postman is a popular collaboration platform for API development. It provides a user-friendly interface that allows developers to create, share, test, and document APIs.

Key features and characteristics of Postman include:

User-Friendly Interface

Postman provides an intuitive and user-friendly interface, making it accessible to both beginners and experienced developers.

HTTP Requests

Users can easily create and send various types of HTTP requests, including GET, POST, PUT, DELETE, and more, allowing for thorough API testing and development.

Collections

Collections help organize and group related requests together. This feature is beneficial for managing and maintaining a structured API workflow.

Variables

Postman allows the use of variables to make requests dynamic. Variables can be used to store and reuse values, enhancing the flexibility and efficiency of your API testing.

Environments

Environments enable users to manage different sets of variables for various testing scenarios. This is especially useful when working with multiple environments like development, testing, and production.

Pre-request Scripts and Tests

Postman supports pre-request scripts and tests, allowing users to execute scripts before sending a request or after receiving a response. This feature is crucial for setting up conditions and validating responses.

Assertions

Postman allows users to write assertions to validate the responses received from API calls. This ensures that the API is behaving as expected and helps catch issues early in the development process

Automation with Newman

Newman is the command-line companion for Postman, enabling users to run collections and environments directly from the terminal. This facilitates automation and integration into continuous integration/continuous deployment (CI/CD) pipelines.

Mocks

Postman Mocks enables users to simulate an API endpoint’s behavior without the need for a backend. This is useful for testing and prototyping before the actual implementation is in place.

Collaboration and Sharing

Postman provides features for team collaboration, allowing users to share collections, environments, and workspaces. This promotes efficient collaboration among team members working on API development and testing.
