Postman: The Complete Guide – REST API Testing Download

Postman API testing for manual and automated tests. Automate with Newman, Jenkins or any other CI tool.

What you’ll learn

Create GET, POST, PUT, DELETE request
Understand GET vs POST request method
Work with real-world APIs (Github API, Trello API)
JavaScript basics for tests
Write API tests in Postman
Use data from Excel files (CSV) or JSON
Use Postman variables to create workflows and scenarios
Run API tests with Newman in Jenkins, GitLab CI or TeamCity
Use OAuth2, API keys, tokens, JWT, basic auth
Test file uploads
Use mock servers
Collaborate using Team Workspaces

Requirements

Basic programming and/or JavaScript knowledge is required (needed for writing tests)
Basic HTTP knowledge required (address, message body, headers, cookies, …)
Basic knowledge about RESTful APIs and JSON
Basic Jenkins experience, if an integration with Jenkins is desired
Basic NodeJS/NPM experience (needed for test automation)
Optional – Basic Docker experience (for Jenkins or Newman)
A computer with Windows, macOS or Linux is required for viewing the lectures and installing Postman. Using a mobile phone/tablet is not recommended.
Registering to a few reputable public APIs is required for you to be able to follow along with the course

Description

RESTful APIs (or simply REST API) are everywhere nowadays, but at the same time, they are getting more complex to get started with: different HTTP methods (GET, POST, PUT, PATCH, DELETE), headers, cookies, dealing with file uploads or authentication with API keys, tokens, OAuth and so much more.

This is where the Postman App comes in! Postman allows you very quickly to create a request with the required HTTP method and parameters, submit the request and easily inspect the results.

I have created this course for testing engineers as well as for software developers or other technical positions. Postman can help you during the development of your API, as well as after the API is completed, by running tests that make sure your API is still working as intended.

In the first part of the course, we will start exploring the features of Postman and continue by writing API tests with the intention of integrating them into a CI server where the tests will run on a current basis.

But this is not the normal course you take part in. Because your needs may be different and because I hate leaving you wondering what to do next, the second part of the course will include user questions and answers to problems that were not yet covered in the course or that are more specific and may not interest everybody.

So let’s look at what you are going to learn:

HTTP request methods (GET, POST, PUT, PATCH, DELETE)
JSON format
Start with simple requests and advance toward more complex scenarios
Learn to deal with authentication/authorization mechanisms like Basic Auth, API Keys, or OAuth.
Start writing API tests
Organize tests in collections and share them with your team
Run API tests in Jenkins or any other CI server
