30 Days of API Testing

30 Days of API Testing Challenge... let's do this!

The 30 Days of Testing Challenge is back! 

The theme this time is API Testing and this challenge has been kindly sponsored by API Fortress - be sure to check out the free trial of their scalable and collaborative API testing suite for Testers and Developers.

These challenges are a great way to learn on your own, as a team effort or join in with the wonderful Ministry of Testing community online.

Below is a list of 30 challenges and a bonus challenge, one for each day of the month. Download the PDF below. Save it somewhere. Print it out. Stick it on your wall. Let’s do this!

What are the rules?

The goal is to tick off as many of the challenges as you can. You can do this in your own timeframe, or you can join us in our joint community effort throughout the month of November. We will be encouraging the community to share their progress on this challenge from the 1st of November 2018

You may have an image to share, a blog post, a video, status update, whatever it is!  Come and participate!
