40% of users are moving towards the competition following a bad experience
57 % of users use their mobile
44-61 % of users share their feelings on social
network
User Experience is Key

What is User Experience?
Etam reduces it's average page load time from 1.2s to 500ms and increased conversions by 20%, time on site by 21%, and pages viewed per visit by 28%.
Walmart saw up to a 2% increase in conversions for every 1 second of improvement in load time. Every 100ms improvement also resulted in up to
a 1% increase in revenue.
Shopzilla decreased load time by 5 seconds and saw a 12% increase in conversion rate, a 25% increase in page views and a 50% reduction in
infrastructure required.
Etsy saw a 12% increase in bounce rate when they added 160kb of images to their mobile page.

Performance Testing Used To Be ….

Testing Earlier
Early Risk analysis
• Understand the application
• Performance needs to be included in the PRA
• ATAM ( Architecture Tradeoff Analysis Method)
Automation Smarter and faster
Validation Follow our KPI
MonitorDetect problems before the end users
Performance is driven by :• The end users
• Third party system
• …
We need to ask the right questions :• How the users work on the system?
• What are their habits
• When ? and how often
• Are we going to expand in different geos?
• Is the marketing plan to market/promote
the application? If yes what is the type audience?
…
Take The Time To Understand The Application
Performance testing an existing application
• Ask the support of functional architect, HR..etc
• Understand the behavior of the application with the help of the logs
Migration project : Don’t underestimate the history of the application
Performance testing a new application/service
• Involve the project leader , functional architect
• Try to understand the purpose and relation with the business plan
Testing scenarios
Unit Performance Testing
Any part of the system
Not a standard practice
Do not wait until the system is assembled
Test cases are simpler, fewer variables
• Test-Driven Development may be an answer
Many systems are monolithic
Third-party components
Change Mentality
Before
Late record/playback performance testing
System-level requirements Record/playback approach "Black Box"
Now
Early Performance Engineering Component-level requirements Programming to generate
load/create stubs "Grey Box”

Organizations Adopt Agile and DevOps as an Answer
• 99% of organizations have adopted Agile development methods
• 88% of CIOs are using DevOps
World Quality Report 2016-17
But Speed is Nothing Without Quality
“Surviving Disruption, Leading Change: Winning in the Application Economy,” 2015
2/3 of business leaders say
their company’s future
DEPENDS on the QUALITY
of their software
“The term everyone is using is
DevOps, but I think it should
really be DevTestOps. Testing
is really crucial for achieving
quality & speed”
Diego La Guidice, Principal Analyst
DevTestOps Rather Than DevOps
AGENDA
Performance matters
Agile testing
From Agile to DevOps
DevOps pipeline
Dynatrace integration
Planning
• Provide transparency to the stakeholders
Source Control
• Tracking Change of the code ( infrastructure, application..Etc)
Configuration management
• Infrastructure is treated exactly like code
Continuous integration
• Tools to automate the Build and the deployment
Deployment tools
• Application can be released to production any time you want in order to improve time to market
Testing and validation
• Validate the quality of the release
APM
• applications are commonly tested and monitored with APM tools to ensure high availability, low response time, and quality of service

Dynatrace integration
• response time
• infrastructure behavior
Capture performance metrics that go beyond
• Failures, bottlenecks, slower-than-expected response times
Actionable data in case of problems
Why Combine Load Testing And APM During a Load Test?
How Does the Integration Works?
Web Model
Mobile Model
RestInterface
Business logic
Data Access logic
XML
Legacy
Relationnal
Presentation Business Data
NeoLoad
Virtual Users Load
• Transaction name, virtual user, script name, unique id
• Easier correlation between load testing solution and Dynatrace AppMon
Web request tagging
• Start & stop recording of data to cover exactly one test run
Session Recording
• Each web request is tagged with a test id
• Allows to distinguish between requests if two test are run in parallel
Registering individual test executions

It‘s not about blind automation of pushing more bad code through a shiny pipeline
It‘s not about blindly giving everyone Ops powerto deploy changes only tested locally
