An Introduction to Agile TestingThe many shapes of modern testing

Clement Pickering, Head of Testing, CallcreditSeptember 2013

Testing is no longer a phaseQuality is everyone’s responsibilityTesting has become a highly skilled, exciting dynamic profession

The shape of Testing is changing

It’s Just All Testing, Right?

• Today’s aim – to introduce what agile testing is all about• How and Why it is different from

traditional approaches• Key underlying principles

• To share examples from Callcredit

• Focus on three key angles …1. People & Mindset2. Strategy & Approach3. Tools & Techniques

• … and the many shapes of agile testing

Who are Callcredit?

• Callcredit is a UK Credit Reference Agency, with key offices in Leeds and Kaunas

• Callcredit has now formally adopted an Agile methodology, DSDM Atern

• Various disparate Development areas now all together under one group function

• Different backgrounds to QA – from no QA to waterfall QA

People & Mindset

A is for Advocacy (NOT Assurance)

• Quality is not just testing NOT • Testing is a rubberstamp

Testing is part of the Process (NOT a phase)

Testing is part of the process NOT • Testing phase gets squeezed

One Team Approach

Collaboration, one team NOT • Independent police

Generalising Specialists

Flexible Team, generalising NOT specialists

• Functional silos, imposed job boundaries

Experts in Information

One team recommendation NOT • QA sign-off

•Removal of QA sign-off•Project team seating•Community of test practice not separate department•Integrated entry\exit quality process•Constant, consistent message•Events on agile testing•Encouraging testers and developers to learn outside roles

Strategy & Approach

Lightweight Visible Test Strategy

Infinite Test Cycles

Change accommodated NOT • Change expensive

Prevent not Find

Prevent not find NOT • Find, unable to prevent

Shapes on Testing #3 – Coverage Blanket

•Test Strategy Posters•Prevent not fix – no logging of bugs found in Integration Environments•Test first Development•Team empowered to choose their approach and encouraged to think of testing and quality from many different angles

Tools & Techniques

The Right Tool for the Right Job

Toolbox of specialist tools NOT One tool fits all

Selenium; QTP; WebDriver; Manual QC

SoapUI; Internal tools; LoadRunner

SpecFlow; Fitnesse; beHat

xUnit

UAT

BDD\ATDD

Unit

Automate and Integrate

Continuous Integrated Testing NOT Single Test Cycle

•Testing pyramid – layers of testing•BDD\ATDD tools (SpecFlow, Fitnesse)•Service tools (SoapUI, Orion, WCFStorm)•Use of more environments•Continuous integration

Conclusions

• Modern Software Development requires a different approach to Testing

• Agile Testing is more than just testing at the end of sprints, it’s a whole different mindset

• Testing is no longer a manual low-skilled role – it’s challenging, technical, integrated and exciting

• Changing the testing culture is key (but the hardestchallenge)
