Testers can be a critical group. They'll challenge, push back, assert, and counter-assert. If you have an idea you want sharpened, want to learn something new, or just want to explore a concept, they can be fantastic resources.

One of the best places to meet, and interact, with software testers is on Twitter.

So here we go: 31 software testers you should consider following.

The practitioners


Kristine Corbus

A tester at Diva-e: Digital Value Enterprise, Corbus is also a community organizer in Germany, where she leads both the Jena, Germany's users group, and acts as lead organizer for TestBash Germany.

Justin Rohrman

The current president of the Association for Software Testing and a senior consultant at Excelon Development, Rohrman is the editor of Stickyminds.com, a testing website. He is interested in API-level testing and tooling, along with applying social science to create meaningful testing metrics that stand up to scrutiny.

Jesse Alford

Another rugged independent who found a way to work with modern development, Alford is an explorer at Pivotal Labs. The company combines methods from extreme programming with cloud-based tools to enable rapid delivery, with Alford acting as more of a test-coach/programmer than a tester.

Patrick Prill

Another TestBash Germany organizer, Prill is a test consultant at QualityMinds Gmbh near Munich. In writing circles, Prill is best known for working behind the scenes doing thorough, diligent, and fast peer review.

Lisa Crispin

Currently a tester at Pivotal Labs, Crispin is the co-author of Agile Testing, along with Janet Gregory, and a Most Influential Agile Test Professional Person Award (MIATPP) winner. Crispin belonged to one of the first teams doing extreme programming and was the lead author of Testing Extreme Programming, back in 2002. 

Michael Larsen

The show producer on The Testing Show podcast, Larsen is a tester at Socialtext, Scout Master, and Snowboarder, perhaps best know for live blogging conference talks as they occur.

Jessica Ingrasellino

Another frequent Testing Show guest, Ingrasellino has done impressive test toolsmith work at Bit.ly and RentTheRunway. Ingrasellino currently works remotely as a lead software quality engineer at Salesforce.org. Her tweet stream is a combination of messages on popular testing, education, Python, music, and politics.

Pete Walen

A former board member of the Association for Software Testing, Walen works as a remote tester for the Salesforce marketing cloud out of his home in Grand Rapids, Michigan. An early organizer of GR-Testers, Walen has presented internationally on exploratory testing and helped staff the Software Testing World Cup in 2014 and 2016.

Damian Synadinos

Perhaps the tester most closely associated with improvisational theater, Synadinos started his career at CompuServe in 1993, then spent 23 years in testing and performance engineering before launching his independent venture, ineffable solutions. Yes, that's spelled correctly.


Dan Billing

New Voice Media can be a sort of launchpad for testing experts, and Billing is no exception. After developing a reputation as a security tester, Billing recently left New Voice Media for Medidata, where he is a test architect. Warning: Billing is also a Dr. Who fan who likes atrocious puns.


David Goldstein 

The creator of @twitbituaries, @shabbosstarts, and @countsefira, Goldstein frequently tweets his opinions about test, quality, and sporting events. 

Claire Moss

Former tester at Oracle and VersionOne, Moss is the lead organizer of the Atlanta Tester's Meetup.

The managers

Alex Schladebeck 

A product manager and longtime contributor to Agile Testing Days, Schladebeck recently changed her role to become head of quality and testing at BREDEX GmbH.

Thomas Vaniotis

A longtime tester turned product manager, Vaniotis is a bit of a Renaissance man, with undergraduate work in philosophy, a fellowship in medieval studies, and a master of science in management. His interests include data visualization, data mining for product insights, and long walks on the beach. (Just kidding about that last one. I think.)

Anna Royzman

The creator of the Test Leadership Congress New York and Test Masters Academy, Royzman is a community builder with decades of test and test leadership experience. An early agile adopter, Royzman has presented at the Agile Conference and currently sits on the board of the Association for Software Testing.

The gurus

James Bach

The co-author of Lessons Learned in Software Testing and author of Secrets of a Bucaneer Scholar, Bach is the principal at Satisfice and co-creator of the Rapid Software Testing course and method.

Morgan coaches teams to improve quality by writing automated checks up front, acceptance test-driven development-style (ATDD).

Janet Gregory

Where Lisa Crispin is the practitioner half of the Crispin/Gregory Partnership, Gregory is the consulting and training half. The 2015 MAITPP winner, Gregory and Crispin recently wrote More Agile Testing, a follow-up to their earlier work.

Thomas Cagley

The host of SPaMCast, the Software Process and Measurement Podcast, Cagley combines more traditional ideas, such as CMMI, with a knowledge of agile testing and modern approaches.

Antony Marcano

An early innovator in blogging, Marcano was the creator of TestingReflections.com (now defunct, but backed up), a set of invitation-only testing blogs, when the concept was new and intimidating. Marcano went on to be a leading thinker in the UK and Europe on behavior-driven development and modern approaches, and gave a keynote speech at Agile Testing Days.

Who are we missing?

A full list of relevant testers on Twitter would be exhausting, as well as exhaustive, and get outdated very quickly. Also, some test experts have tweets that are mostly personal or political, or their stream consists almost exclusively or retweets. We tried to include testers who are timely and relevant, but it's time for the community to contribute. Who did we forget? Why? Let us know in the comments below!
