Parasoft Copyright © 2016 44 Agenda
Parasoft Copyright © 2016 55 We must Re-invent Test  The penalty for faulty software is increasing  Brand erosion  All industries at risk for total transformation  Technology is faster and more distributed  Containers  Microservices
Parasoft Copyright © 2016 66 Software Failures = Headlines 2015 -$2.55 Bn -4.06% The day of the announcement companies lost an average of shareholder value Software failures make headline news— eroding customer confidence, shareholder value and brand equity
Parasoft Copyright © 2016 77 Complexity a Barrier to Testing
Parasoft Copyright © 2016 88 Enabling Technologies Stubs Service Virtualization API testing Test data management Environment management Self-service test environments
Parasoft Copyright © 2016 99 What is Service Virtualization Service Virtualization delivers simulated application behavior in dev / test environments allowing an organization to test on-demand
Parasoft Copyright © 2016 1010 So, What can you Virtualize? • SOA / Web services • XML • WSDL • WADL • UDDI • WSIL • SOAP • PoX (Plain XML) • REST • JSON • BPEL • Web Applications • SQL/Stored Procedures • JDBC/ODBC • Mainframe CICS/IMS • Copybook • Mobile Interfaces • AJAX • JSP • JavaScript • HTML • CSS • WS-*Standards • SAP RFC/IDoc • MTOM(XOP) / MIME / DIME • OAuth • TCP/IP • webMethods Broker • webMethods IS • HL7 • FTP • HTTP/HTTPS • JMS • IBM WebSphere MQ • Sonic MQ • RMI • EJB • SMTP • Tibco Rendezvous • .NET WCF • ISO 8583, FIX, SWIFT • Mainframe CICS, IMS • EDI • Java JVM calls • Extendable Formats and Protocols AUT
Parasoft Copyright © 2016 1111 Service Virtualization Misunderstood VMware Mocks Stubs Replaces integration testing
Parasoft Copyright © 2016 1212 Poll 1: Challenges  Do any of the following ever impact your testing?  Components not ready when I’m ready  Don’t have a full lab to test my application  Some of the 3rd party services cost per transaction  Mainframe access and cost  Development teams need to access the same test resource
Parasoft Copyright © 2016 1414 Access Issues Pieces/Parts come from everywhere Definitions changing (upgrades, new versions) Not always available Can’t test with real data without causing problems
Parasoft Copyright © 2016 1515 When to use SV? Access vs Configuration  Access  Dependent applications difficult  Scheduling conflicts  High access fees  Geo-political boundaries  3rd party or partner applications  Configuration  Complex to configure  No control  Limited variability  Consumes test time Test Access Simple Difficult Configuration Complex Internal Service Internal Application 3rd Party Service ERP Mainframe External Application External Database Internal Database Cloud App Message Queue ESB Web Server

Parasoft Copyright © 2016 1717 It’s Not All Ready At Once Teams on different versions Subcontractors Parts that depend on other parts Changing existing functionality Parallel development Continuous change
Parasoft Copyright © 2016 1818 Solution  Virtualize all external dependencies  Expensive internal dependencies  Time-constrained dependencies  IT constrained dependencies  Self-service!
Parasoft Copyright © 2016 2020 Behavior Issues Multiple versions - of multiple components Failures / faults Understanding performance - Slow AND fast Custom logic Security / bad actors Broad data
Parasoft Copyright © 2016 2121 Asset Versioning  Version the assets  Multiple branches  Different dependencies
Parasoft Copyright © 2016 2222 Death Spiral Small errors lead to untested code New errors are compounded Leads to eventual system failure
Parasoft Copyright © 2016 2323 Solution Expand testing by virtualizing things that you can’t easily make happen Fault-injection More permutations Data-sources
Parasoft Copyright © 2016 2525 Cost Issues Mainframes 3rd party pay-per-transaction services Expensive systems Duplicate systems (test & prod) Triplicate systems (different teams)

Parasoft Copyright © 2016 2727 Reduced cost of creation and management of Test Environments by 85% for a major international bank  The Challenge  Complex test environments including; ATM, website and mobile front-end systems with WebSphere, Mainframe, MQ, SAP and DataPower back-end systems  Each test system costs >$2m, therefore only two environments available  Active development at every level of the system resulting in full end-to-end testing requiring careful coordination and sub-system teams often offline or unavailable due to upgrades Database SAP Mainframe Application Mobile Application development and extension of current systems
Parasoft Copyright © 2016 2828  The Solution  Create a library of virtual assets for teams to share and use Environment Manager to replicate and manage Virtual test labs using different performance charactistics for different load scenarios.  Use automated test solution to test and validate at each layer independantly Environment Management Reduced cost of creation and management of Test Environments by 85% for a major international bank Mobile Application development and extension of current systems Database SAP Mainframe Application Virtual AssetVirtual AssetVirtual Asset Virtual AssetVirtual Asset Virtual Asset Virtual AssetVirtual AssetVirtual AssetVirtual Asset Virtual Asset Virtual Asset Virtual Asset ✔✖
Parasoft Copyright © 2016 2929  The Business Benefit  Improved efficiency, enabling Agile development, with the teams able to test in isolation without effecting full end-to-end system tests. Reduced cost of creation and management of Test Environments by 85% for a major international bank Environment Management Mobile Application development and extension of current systems ✔✖ ✔✖ ✔✖ ✔✖
Parasoft Copyright © 2016 3131 Speed Issues Time to test Time to configure Address bottlenecks Address versions Address capacity constraints
Parasoft Copyright © 2016 3232  The Challenge  Performance issues found late in the SDLC resulting in large rework and cost  Middleware component able to handle large load but available downstream dependent systems were unable to provide throughput needed Reduced testing time by 27-days for a major commercial bank Capacity Constrained staged environments Database Service Mainframe Application 1000 tps
Parasoft Copyright © 2016 3333 Database Service Mainframe Application Reduced testing time by 27-days for a major commercial bank  The Solution  Identified key use-cases and emulate the behavior of dependent systems. Asset performance setup to match production load response values  SOAtest and LoadTest used to validate system under test. Virtual assets changed to model different scenarios Capacity Constrained staged environments 1000 tps Virtual Asset Virtual Asset Virtual Asset Virtual Asset
Parasoft Copyright © 2016 3434 Reduced testing time by 27-days for a major commercial bank  The Business Benefit  Team able to predict performances issues and resolve before full Performance testing.  Able to run different scenarios not easily achieved with production environment (excessive response times).  Setup for ‘performance test’ reduced to near zero Capacity Constrained staged environments 1000 tps Virtual Asset Virtual Asset Virtual Asset Virtual Asset Virtual Asset Virtual Asset Virtual Asset Virtual Asset Virtual Asset Virtual Asset Virtual Asset Virtual Asset Different data/behavior/per formance profiles
Parasoft Copyright © 2016 3535 Poll 2: Test Coverage  How much of your entire application do you usually test?  0-25%  26-50%  51-75%  76-100%  Unknown
Parasoft Copyright © 2016 3636 DEMO
Parasoft Copyright © 2016 4141 Reduces time to configure applications for test Greatly reduces hardware costs or system access fees Reduces the cost for “Test/QA” licenses Increase software quality Increases productivity Realistic reusable assets Benefits Service Virtualization
Parasoft Copyright © 2016 4242 Parasoft Function Solution Examples Mobile Application development and extension of current systems Agile/Parallel development limited by system dependencies Capacity Constrained staged environments Limited access to mainframes, ERPs, or 3rd party systems Test data management for complex transactions Parasoft SOAtest and Virtualize is used throughout the SDLC to speed access to and reduce the costs of validation and management of development and test environments
