Mob Testing Lessons from a Year of

#MobTesting

by Maaret Pyhäjärvi


So, What is Mob Testing (and Programming)

Let’s Define the Basics


"All the brilliant people working on the same thing, at the same time, in

the same space, on the same computer." -- Woody Zuill


Mob Testing is Mob Programming so that:

•  You’re a tester in a mob

programming team OR

• Activity you mob on is testing


Mobbing Setup and Roles

Driver

Navigators

Designated Navigator

Facilitator


Strong-Style Navigation

“For an idea to go from your head to the computer it must

go through someone else’s hands”

Yes, and…


Kindness, Consideration and

Respect


Observations Retrospective

ONE IDEA PER STICKY

NOTE

CAPITAL LETTERS

EASY TO

READ

FEW WORDS

Lowercase letters

Don’t write in cursive or in biro

Avoid writing too much on one single note as it takes a while for people to

read the whole thing!

Working and Teaching in a Mob


A Non-Programmer Meets Mob Programming


An All-Female Hackathon


Teaching Exploratory Testing in a Mob


Cognitive Dissonance


Correcting Mistakes without

Egos in Play

TOTALS

Mob on Any Testing Activity!


Product is my external imagination

I am my developer’s external imagination


The Usual Concerns Wouldn’t we get more done individually?


It’s NOT this!


Best ideas win when you care

about work over credit


From technical debt to technical

assets


Best face forward in a group


Building psychological

safety


You have great ideas even if you did not know how to turn them to code – removing the distance is

worth the struggle.
