Learn API testing with Postman from scratch
☑ Postman basics
☑ API baiscs
☑ REST API
☑ RESTful Web Services
☑ HTTP methods
☑ HTTP status codes
☑ JSON schemas
☑ API testing
Some of you may ask a question: “Why should I select this course, instead of learning Postman by myself?”
So, what is extremely cool about this course?
That you won’t learn just theory.
You will have practical technical tasks connected to real testing of API endpoints.
You don’t need to search for other questions in Google, because you cannot understand lessons or homework.
Everything is in here. In one place. In this training course.
This guaranty to you that with this training course you will save a lot of your time.
Because if you would start learning Postman by yourself you would notice that on the internet there are a lot of directions to learn Postman, a lot of different specific topics to learn, which are not applicable on most projects.
And all of this in one single training course from the very beginning.
What I suggest to you, is a training course, where step by step, with a detailed homework program, with practical tasks, with a detailed review of solution of each practical task we will learn Postman together.
This program will give you enough knowledge to get your first job and be able to test an API web service with the help of Postman.

Course Overview
- Today’s digital landscape is intricately connected through a vast web of Application Programming Interfaces (APIs). Mastering API testing is not merely a technical skill but a critical competency for ensuring the quality, reliability, and security of modern software applications. This “Webservices API Testing with Postman – Complete Guide” is meticulously crafted to equip you with the essential knowledge and practical skills required to excel in API testing using Postman, the industry’s leading tool for API development, testing, and collaboration.
- We will embark on a structured, hands-on journey, starting from the foundational principles of web services and API architecture, progressing through Postman’s powerful features, and culminating in advanced testing strategies and automation techniques. The course is designed to empower you with the ability to build robust, automated API test suites that significantly enhance software quality and accelerate development cycles.
- Whether you are a Quality Assurance engineer aiming to elevate your testing expertise, a developer seeking to improve your API integration and validation practices, a DevOps professional looking to incorporate API testing into your CI/CD pipelines, or simply a tech enthusiast eager to understand the backbone of modern web applications, this course offers an invaluable and comprehensive learning experience.
-
Requirements / Prerequisites
- Basic Computer Literacy: Familiarity with operating a computer, managing files, and navigating web browsers is expected.
- Understanding of Web Applications: A general conceptual understanding of how websites and web applications interact and function, even at a fundamental level.
- Curiosity and a Desire to Learn: The most crucial prerequisite is an enthusiasm to explore the world of API testing and become proficient with Postman.
- Reliable Internet Connection: Stable internet access is necessary for downloading the Postman application and interacting with various online public APIs used for practical exercises.
- No Prior Postman or API Testing Experience: This course is meticulously structured to guide complete beginners through every step, ensuring no prior knowledge of Postman or API testing is required.
-
Skills Covered / Tools Used
- Designing Comprehensive API Test Cases: Learn to craft detailed and effective test cases for various API endpoints, ensuring thorough validation of functionalities, error handling, and edge scenarios.
- Automating API Workflows with Scripts: Gain proficiency in leveraging Postman’s scripting capabilities (Pre-request Scripts, Test Scripts) to automate complex sequences of API calls, parameterizing requests, and performing dynamic data manipulation for efficient and repeatable testing.
- Implementing Data-Driven Testing: Master the technique of utilizing external data sources (like CSV and JSON files) within Postman to execute data-driven tests, dramatically expanding test coverage with minimal repetitive effort.
- Mocking API Server Responses: Develop the skill to create realistic mock servers within Postman, enabling front-end development and parallel testing even when actual backend APIs are under development or unavailable.
- Effective Environment Management: Learn to configure and manage different testing environments (development, staging, production) using Postman environments and global variables, promoting flexibility, security, and reusability of test collections.
- Integrating with CI/CD Pipelines: Understand how Postman collections can be seamlessly integrated into continuous integration/continuous deployment (CI/CD) pipelines using Newman, facilitating automated API testing as part of your build and deployment processes.
- Advanced API Debugging Techniques: Employ Postman’s robust console and inspector tools to meticulously debug API requests, analyze responses, and troubleshoot script executions, quickly pinpointing and resolving issues.
- Preliminary Performance Insights: Acquire the ability to gain initial insights into API response times and identify potential performance bottlenecks through Postman’s built-in features, informing more extensive performance testing efforts.
- Collaborative Testing Practices: Learn best practices for sharing Postman collections, environments, and test results within teams, fostering a collaborative and efficient API testing ecosystem.
- Tools Utilized: The primary tools will be the Postman Desktop Client and its cloud-based functionalities. We will also explore interactions with Public RESTful APIs for practical application and touch upon basic concepts related to Version Control Systems (e.g., Git) for collection management.
