WE WILL AUTOMATE YOU!

INTRODUCTION

•  Basic of automation •  Why and how we’ll do it

Type Of Automated Testing

UNIT TEST IS TESTING SMALL UNIT OF CODE IN ISOLATION

Unit Testing

INTEGRATION TESTING TEST UNITS TOGETHER, BUT STILL FOCUSES ON THE CODE

Integration Testing

BATS TEST THE SYSTEM FROM THE PERSPECTIVE OF THE USER

Blackbox Automated Testing (BAT)

THE TEST PYRAMID IS A CONCEPT DEVELOPED BY MIKE COHN

Pyramid of the Testing

Selenium is a web application testing framework that allows you to write tests in many programming languages like: •  Java •  C# •  Groovy •  Perl •  PHP •  Python •  Ruby

What is Selenium? Selenium deploys on •  Windows, •  Linux, •  MAC OS.

It is an open-source project!

2004 – Jason Huggins creates a JavaScript based tool for automatic testing called Selenium (now it is known as Selenium Core). Later Selenium Remote Control (aka Selenium RC) was developed to address the “same host origin” browser policy and allow many language bindings to control the browser at a distance

2006 – Simon Stewart started working on another web testing tool called WebDriver

2009 – Selenium RC and WebDriver are merged into a one project called Selenium-WebDriver (aka Selenium 2.0)

2013 – The first working draft of WebDriver API W3C Specification is released

A Bit of History

Terminology

•  Selenium Core

•  Selenium RC

•  Selenium-WebDriver

•  Selenium Server

•  Selenium IDE

•  Selenium-Grid

CAN’T WE JUST USE OUR UNIT & INTEGRATION TESTS AND RUN OTHERS MANUALLY?

Why Do It?

IT WORKED YESTERDAY!

Regression

THIS TEST EXPLAINS EXACTLY WHAT I WANT AND WHAT YOU AGREED TO

Absolute Requirements

BATS TEST MUCH MORE PRODUCTION CODE WITH FEWER LINES OF CODE

Leverage

OUR APPROACH

TESTS DON’T DIRECTLY WORK AGAINST THE WEB APP

Separate Automation Framework

Web App Framework Tests

I TOTALLY UNDERSTAND WHAT THESE TEST ARE DOING.

Simple Test

I AM AN AUTOMATED TEST, I’LL BE DRIVING TODAY. YOU CAN ALL ME ARMAN

Test Drive Creation of Framework

DESIGNING THE ARCHITECTURE

EACH LAYER ONLY INTERACTS WITH THE LAYER IMMEDIATELY BELOW IT

Architecture

THE FRAMEWORK ITSELF SHOULD BE DIVIDED BY LAYERS OF FUNCTIONALITY

Thinking About Layers

Thinking about Ease of Use

THE CHOICE MAKES A HUGE DIFFERENCE

Which is Easier?

OR

PREPARE TO BECOME AN AUTOMATION NINJA!

Let’s Start the Coding

COMMON FAILURE POINTS

NEVER RECORD A TEST CASE!

Recorded Brittle Test

NEVER RECORD A TEST CASE!

Not Building a Framework

WHAT THE HECK AM I LOOKING AT?

Writing Test Like a Code

NOT EVERYTHING CAN BE AUTOMATED!

Automating Hard Things

•  Test fail because •  The condition testes was not met

•  An Assertion in the test failed

•  Test error because •  Something other than what was being testes failed

•  The framework threw an exception

IT IS IMPORTANT TO MAKE A DISTINCTION BETWEEN ERRORS & FAILURES

Error vs Failures

•  Have a plan and stick to it

•  Run test as part of build

•  Run test locally

•  Report results

•  Break builds

MAKE SURE AUTOMATED TEST ARE TAKEN SERIOUSLY

Continuous Integration

MAKE SURE AUTOMATED TEST ARE TAKEN SERIOUSLY

HOW YOU WILL FEEL WHEN YOUR AUTOMATED TESTS ALL PASS

The End!
