"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

• Activity you mob on is testing

Testers don’t break the code, they break your illusions about

the code. - Adapted from James Bach

go through someone else’s hands”

Mob Exploratory Testing


Activity: Exploring in a Mob 1 • Find the Happy Path: why would

anyone want to use this? • Retrospective: What have we

learned?

Activity: Exploring in a Mob 2 • Coverage: Identify what is there • Retrospective: What have we

learned?



Using Mindmap


Retrospective


Theory to take home


Testers acquire a lot of implicit knowledge


Introducing concepts, ideas

and tools


Vocalizing your ideas


Emotions through Trigger Words


Mapping Coverage, Bugs and Questions


Building habits and transferring skills

over passing knowledge


Activity: Creating Selenium Scripts

• Basic Selenium WebDriver Test • Retrospective: What have we

learned?

Test Target Application by Thomas Sundberg


Task: Test as code



Using Mindmap


Theory to take home


Test Automation is

Use of Programming for Testing Purposes


Programming is like writing. Getting

started is easy and it takes a lifetime to

get good at.


Empathy for a Special Needs User


Share the Whole Picture of

Test Automation


Breaking the Test Automation

Ownership


Building Confidence


Shared Experience Accelerates Adoption


Test automation isn't about automating manual tests,

it's decomposing the testing differently so automation

makes sense.


Activity: Test-Driven Development • Glimpse into Mob Programming:

contribution of a non-programming tester • Retrospective: What have we

learned?

Using Mindmap


Theory to take home


Before implementing

While implementing

Before production

While in production

Testing as artifact creation

Testing as performance (exploration)

Ways to think of testing peak at different moments with regards to adding a capability

TOTALS

Testing is Everywhere!


Non-programmer is often still technical


Correcting Mistakes without

Egos in Play


Knowing what is relevant


Slow allows for thoughtful thinking


Stealth Exploration


Do both!


From technical debt to technical

assets


Best ideas win when you care

about work over credit


Best face forward in a group


We raise our collective competence,

allowing individuals to use specialized skills


Introducing Mob Testing as a Learning Activity

• Facilitation: speak through questions, introduce constraints, concepts and tools • Discussion on kindness, consideration

and respect in action • Learning to learn: removing the need

of a facilitator


Learning or Contributing


Accidental Learning by being Intentional

about Learning


The 1 % every day => 3600 % in a year

Linear Viewpoint

I know everything

you do!

You have nothing left to teach me

Reality

I know more than you do!

There is still so much more

I can learn from you
