HUXLEY & THE FLYING

ROBOT MONKEYS

Improvisational comedians train to think laterally.

Humans instinctively focus on details.

“Does that lookclean to you?”

Humans are visual testers.

Delegation.

HISTORY

Most human beings have an infinite capacity for taking things for granted.

!

That we do not learn very much from the lessons of history is the most

important of all the lessons of history. !

—Aldous Huxley

Hammers, shovels & cars. Text editors, email clients & Photoshop.

Classic Tools

These are tools that you don’t actively use. You tell them—or schedule them—to do work, and

they return with the results when they’re done. !task runners

!cron, grunt, gulp, rake, etc.

Asynchronous Tools

Monkeys Are Asynchronous Tools

Grunt is like a middle manager.

They run on their own.

True Automation

Flying Monkeys

Little monkeys as messengers shuttling files

between servers.

Big monkeys as warriors

pounding on your app.

The Wicked Witch is like a

flying middle manager.

Things are gonna be

so awesome for me now.

And yet…

• It’s premiere feature is interaction recording • But loading up the app is slow • And playing back interactions is slow • And running against an app is super brittle • So if an external service is slow you get a false positive!!These are terrible things that have been true for automated testing on the web for the past 10 years. !!Huxley does not fix that.

MODULARIZATION TECHNIQUES

Generated Pattern Library Use KSS or Styledocco. !!!!!In-Context Pattern Library Use this as a baseline to refactor your code into a more modular state.

ASK YOURSELFARE YOU MODULAR?

The Rules at TripCase

Patterns areborn into the library.

!

They graduate to the app.

I.

Every patternbelongs in the library.

!

Even the one-offs.

II.

No tests should ever fail. !

Patterns document what the system looks like right now.

III.

SUMMARY

Humans are visual testers. Robots are better at catching regressions.

!

Automate manual processes. Consider doing it in the cloud.

!

Comparing screenshots is a great way to catch regressions.

CALL TO ACTION

Get the Huxley example project working on your computer.

!

Setup Huxley withone of your projects.

!

Refactor with confidence.

Questions?

Thomas Henry Huxley!Evolutionary biologist !Contemporary of Charles Darwin. !Controversialist (known as “Darwin’s bulldog”). !Coined the term “agnostic”.

So, what?

CHANGE

We have to learn to manage change. !

Everything changes.

You will change.

So will the business, your bosses, the customers, and the requirements.

CHANGE

C3P0 outlasted his inventor. !

So will your code, probably. !

Leave them something thatwill take care of itself.

Leave them tests, documentation,

and now screenshots.
