From Agile to DevOps

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

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 ….

Performance Design is The Key

Standard Performance Testing Workflow

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


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
