Notes: The Ministry of Testing's Introduction to HTTP by Mark Winteringham

Even though I have been a software tester for the past twenty years, I still like taking introductory courses where I can practice going back to the basics.

Right now, I am working through Mark Winteringham's Introduction to HTTP, accessible when you purchase the Ministry of Testing's Professional Membership.



The Introduction to HTTP course covers:
  • HTTP Methods such as Get, Post, Put, Patch, and Delete. See the Mozilla Developer Network article on HTTP Request Methods. Example: GET restful-booker.herokuapp:80/booking
  • Find out all the options of the URI by sending OPTIONS to it, such as OPTIONS restful-booker.herokuapp:80/booking.
  • HTTP Status Codes such as 200 OK, 201 Created, 401 Unauthorized, 404 Not Found, 500 Internal Server Error, 503 Web Service Down. Examples of Status codes: httpstatusdogs.com and http.cat
  • HTTP Response Bodies containing the response you requested in JSON Objects containing key and values, XML elements containing values and tags, URL Encoded format.
  • Testing Payloads using Elisabeth Hendrickson ( @TestObsessed ) Test Heuristics Cheat Sheet and the Big List of Naughty Strings.
  • HTTP Headers such as Content-Length: 195, Connection: keep-alive, Content-Type: application/json, User-Agent: Mozilla/1.22, Accept:text/html, Accept-Language: en-GB, and Cookie.
  • Authorization, and Authentication.

It's really interesting how Mark, the @2bittester, created his own test API, the Restful-Booker: An API Playground, which purposely contains errors that testers can discover using tools such as Postman to interact with it. 

I love Mark's work! Mark collaborated with Richard Bradshaw, the @FriendlyTester, head of the Ministry of Testing, to create free courses in AutomationInTesting.com and the companion site you can explore, AutomationInTesting.online, which offers the "Shady Meadows Bed & Breakfast", a website that uses the purposely flawed Restful-Booker.


Happy Testing!
