1. Postman And Fiddler For QA
Automation QA
Vitalii Kovaliuk

2. FIDDLER - The free web debugging proxy
for any browser, system or platform

3. - Sniffing (sniff http/https traffic from any device mobile/browser/application)
- Debugging API (break request/response in runtime and edit it)
- Mock API (auto-responder)
- Filters
- Composer (create and send request)
- Rerun/Retry requests (hundreds simultaneously)
- Statistics (inspector)
- Plugins and Extensions
Main features that are useful for QA
Quote from the book(Debugging with Fiddler): “Over twelve years and through more than a hundred version releases, Fiddler has evolved into a powerful utility and
platform that can perform a wide variety of tasks. It has a rich extensibility model and a community of add-on developers who have broadened its usefulness as a
performance, security, and load-testing tool. Questions in email, online discussion groups, and numerous conferences over the years made it overwhelmingly
apparent that most users only exploit a tiny fraction of Fiddler’s power. ”

4. How it’s works?

5. How it look like…

6. Filter traffic…
Filters are useful, because it help to hide non-needed
traffic. Also we could put global breakpoints, add or
remove headers, and some other options.

7. AutoResponder…mock you API

8. Debug API…in real-time

fiddler….

10. Happy Fiddling!

11. POSTMAN – LIKE A POWERFUL
API TESTING TOOL

12. - Postman's ADE is available in Free, Pro, and Enterprise plans.
- Postman is used by 5 million developers and more than 100,000 companies to access 130 million
APIs every month.
- Postman is Cross-platform tool.
- Exist like separate application and chrome extension(currently it is deprecated).
- “Postman makes API development faster, easier, and better”
Few words about Postman
“An API Development Environment - or ADE - is a platform that supports and enhances API development. A good ADE will
streamline the development process, create a single source of truth for an organization's APIs, and enhance collaboration
on APIs across the organization.”

13. - Collection Runner (UI runner)
- Newman (console runner)
- Interceptor (old name) capturing traffic
- IN SYNC – synchronize you collection via different machine (in paid version different accounts)
- Manage Environments - Set global and special environments variable
- Import – share you collection with world
Built-in tools, that are useful for QA…

14. Lets take a look how it works…
