customer relationship management and enterprise resource planning business
processes.
Some leading providers of CRM / ERP
Definition
• Succesfull selection and Integration of the ‘package’ leading to ‘acceptance’
• (Test) Data accuracy, data quality and security during storage and retrieval

‘test object’ i.e application under test and / or testing services themselves are
provided via cloud computing using PAAS / SAAS and APIs
Defintion
• Performance, scalability, capacity and availability
• Access, privacy & security
• Migration, interoperability & reversibility (avoid “vendor lock in”)
Key
challenges
• HP Loadrunner
• SOASTA Cloud test
• SoapUI
TRASYS

16. Testing as a Service: Mobile Application Testing
The functional and non functional testing of mobile-based native (or hybrid)
applications.
Some leading mobile app. platform providers: SAP, IBM, Kony, Antenna, Jquery mobile,
Adobe, Appcelrator
Definition
• Understand the native application platform (hardware, OS) and network types
• Testing needs to ascertain that the app can be successfully downloaded to the device,
executed on the device and interact with the supporting backend & infrastructure and
updates can be made (push out)
• Understand the non functional requirements, risks & ‘vulnerabilities’ (security, performance,
usability, portability…) related to mobile application development and (end user) usage
Key
challenges
• Predefined mobile application checklists and ‘standard’ test cases (MAT starters kit)
• Our mobile application test lab contains multiple fysical devices & emulators in order to
support different test objectives. This is also supported by remote cloud based devices .
• We can test multiple networks from our different locations (i.e GPRS tunneling effect)
• Automated mobile test execution using emulators and test automation tools (see annex 1)
TRASYS
tools &
assets
• Risk based multidevice and multi OS testing, including backward compatibility
• App lifecycle mgt testing ( from store readyness to push out of upgrade app versions)
• Functional testing , security testing, performance testing, E2E business process testing,
back end integration testing and usability testing for mobile applications

17. Testing as a Service: Big Data, DWH and BI
Testing of the data warehouse i.e the main organisations ’repository
of transformed and cleaned historical data’ and business intelligence and
decision support applications
Some leading providers:
Defintion
• Availability of high quality (test) data in order to cover requirements (i.e reports or queries
and ETLs)
• High volatility of business rules & requirements in DWH/BI testing
• Sensitivity, complexity & confidentiality of (test) data
Key
challenges
• Tricentis Tosca Testsuite (for DWH testing)
• Analytical simulation engine (accelerator)
• Data driven testing tools and model based testing tools
(See next slide)
TRASYS
tools
• DWH, DI and Big data testing:
• Source data extraction testing
• ETL process validation (including statistical & dimensional analysis and data quality
validation)
• E2E integration testing of ETL batch jobs
• Report validation, Cube validation, dashboard validation
• Non functional testing (performance , security)
• (Test) data mining, combined with ‘synthetic’ test data creation
• Simulation of business rules while processing historical and/or near-to real time transactions
in order to test systems

20. Testing as a Service:
Model Based Testing (MBT) & Data Driven Testing (DDT)
Testing based on a model of the component or system under test, e.g., reliability growth models, usage
models such as operational profiles or behavioral models such as decision table or state transition
diagram.Test cases are derived from a model such as finite state machine , UML, state chart, Markov
chain that describes (mostly functional) aspects of the application under test
-> Model based testing is supported by data driven test automation (DDT)
-> Model based testing is a way of simulation early in the SDLC
Defintion
• Cost reduction
• Increased test coverage
• early validation of design model
Key
advantages
• Test Optimal (MBT tool)
• MaTeLo (MBT tool)
• HP QTP (DDT automation tool)
• Selenium ( test automation tool)
TRASYS
tools
• Test data & test case generation using
design techniques (boundary values, pair wise,
branch, decision, transition, state, requirements,..)
• Model based & data driven test automation
• Test data management
TRASYS
Services

21. Testing as a Service: Security Testing
Defintion
Key
challenges
TRASYS
tools
• Vulnerability scanning & assessment
• Penetration testing / attack based testing (= systematic probing of systems with the goal
of gaining access to the information they contain)
-> Open Web Application Security Project (OWASP) top 10
most critical web application flaws
-> Open Source Security Testing Methodology (OSSTM)
TRASYS
Services
• Acunetix
• Webscarab
• IBM Appscan
• See appendix 1 for full list
Determine that an information system protects data and prevents unauthorized
access, whether accidental or deliberate, to programs and data.
The six basic security concepts that need to be covered by security testing are:
• confidentiality
• Integrity
• identification & authentication
• Availability
• Authorization
• non-repudiation

22. Testing as a Service: Usability & Crowd Testing
Defintion
Key
challenges
TRASYS
tools
• Requirements based usability testing, including
prototype & mock up validations during inception
of SDLC using for example ISO 9241
• Real-world usage validation in order to
continuously improve the systems
* Use of production data analytics & usability tools
* Crowd Testing = crowd sourcing + cloud test platform
TRASYS
Services
• Chalkmark, Clickheat
• Google analytics
• Usertesting.com, Userzoom
• Browser cam (cloud based)
• UserReplay
• Avoid that end users / customers leave (abandon) when a system is difficult to use, a
homepage fails to clearly deliver information i.e E-commerce: if users cannot find the
product, they cannot buy it either ( impact on revenue)
• The functionality of our application is state of the art, but users lose time trying to figure out
how to operate it ( impact on productivity)
Testing the ease with which the user interfaces can be used and whether the application or the
product built is user-friendly or not.
Usability testing also reveals whether users feel comfortable with your application or Web site
according to different parameters - the flow, navigation and layout, speed and content -
especially in comparison to prior or similar applications.

23. Testing as a Service: Performance Testing
Defintion
Key
challenges
TRASYS
tools
• Load testing
• Stress testing
• Scalability testing & capacity planning support
• Code review with performance focus – performance profiling
• Reliability testing
TRASYS
Services
• Loadrunner
• Jmeter
• Jprofiler
• Several code review & inspection tools ( see Annex 1)
• Avoid that end users / customers leave (abandon) when a system is ‘too slow’
to use, a homepage fails to deliver information with an acceptable response
time -> impact on revenue
• The functionality of our application is state of the art, but (internal or external)
users lose time to operate and use the functionality -> impact on productivity
• System is not available due to overload -> impact on revenue
• System is oversized or undersized due to lack of performance testing ->
impact on Capex / Opex
The process of testing to determine the performance of a software product.
