In my line of work as a consultant,
I review
Test automation implementations.
Here are some honest findings.

Where do I fit in?
My primary focus is OOP modeling in test
automation.
I work with engineers who know tools well and
help them in design aspects around them.
In the process, I’m learning a bit of tooling.
I’m not a great designer. It’s just that I have
looked at lots and lots of code for last 10 years.

These numbers are shocking.
Borderline unbelievable.

One of the core reasons I found is this:
Despite most open source tools being based on OOP, and
despite most engineers using an OOP language,
Test Automation Engineers’ thinking is procedural.
OOP Models are almost non-existant;
Except random inheritance scattered here and there.
I’ve nothing against procedural programming. However, this
nature of mash-up is mostly a disaster.

A Simple Example…
In Selenium WebDriver, you can find an element using the webdriver or
an element.
I’ve seen a variety of implementations with if-elses, switch cases,
overloading etc, some decent some horrible.
All of them failed to acknowledge that both WebDriver and
WebElement implement SearchContext interface. So, one method
without if-else, switch-case or similar constructs, is sufficient if the
argument it takes is SearchContext instead of WebDriver or
WebElement.
Same is true for Window and UiItem in case of White framework. They
implement a common interface for finding. Looking for an answer 
Find it!

This simple change would have a cascading effect on calling
code as there would be only one type of call for different
situations. Try it.

Over the course of last few years, I started
implemented various OOP based implementations
to bring code reduction.
This is where I realized that I could put together my
ideas in a place which is open to all for reference.
As I deal with more an more projects and with
inputs from community, it could be pretty helpful
for testing community.

This led to development of MEANINGful model of
UI automation.
The goal of this presentation is give you a quick
introduction to the model and share an open-
source, mostly completed implementation with
you for reference.

The MEANINGful model is an OOP Pluralistic model that
goes beyond Page-Object design and acknowledges 7
primary components in UI automation.
Maker
Element
Automator
Name Store
Identifier
Notifier
GUI

In the interest of the wider audience,
Let me show you technically toned down
version of the model.

Meaningful model has the following benefits:
• Supports multiple automation tool integration.
• Higher level identifiers, Multiple identifiers for same
control (OR/AND relationship)
• Multiple formats for externalization of identification
relationships
• Nested Guis
• Higher level API for multi-element match
• Same Element API for automator based or Gui based
automation.
• A considerable reduction in code along with
robustness.
• And more…

You can take these ideas and try something of
your own.

You can also choose to refer my work.

Daksha is a free, Apache 2 Licensed,
open-source Java framework
that I am creating.
Target is to have a MEANINGful implementation
which is freely accessible to the community for
reference.
Currently Daksha includes support for
Selenium, Appium and Sikuli.
API completion is in progress for the said libs.

For a more involved discussion:
You can reach out directly to RV@testmile.com
Try out Daksha.
It’s less than 2 months old.
So, if you find a problem.
You are likely right about it.
Share your feedback.
*Notifier component is not yet developed. I am working on arriving
at the right approach yet.
