WHO IS IT?

4. WHAT IS SOFTWARE ARCHITECTURE?

5. IT STARTS FROM ONE GEEKY GUY…

6. THEN IT MIGHT FINISH UP AS FOLLOWING…

7. SO,
WHAT IS SOFTWARE
ARCHITECTURE?

8. WHAT FORMS SOFTWARE ARCHITECTURE?

9. BUSINESS

10. USERS

11. SYSTEM

12. WHAT CAN BE TESTED HERE?

13. THIS???

15. SEI
THEY LIKE NON FUNCTIONAL REQUIREMENTS

16. THEY CALL THEM – QUALITY ATTRIBUTES
Category Quality attribute
Design Qualities Conceptual Integrity
Maintainability
Reusability
Run-time Qualities Availability
Interoperability
Manageability
Performance
Reliability
Scalability
Security
System Qualities Supportability
Testability
User Qualities Usability

17. WHAT IS QUALITY ATTRIBUTE?
ABILITY

18. WHAT QUALITY ATTRIBUTES YOU SEE?

21. QUALITY ATTRIBUTE WORKSHOP

22. S.M.A.R.T.
Specific (why/what/how)
Measurable
Achievable
Result-focused
Time-bound

23. ARCHITECTURE SCENARIOS – SAMPLE UTILITY TREE

24. ACCEPTANCE: A SOFTWARE ERROR OCCURS AT
HIGH VEHICLE SPEED. REBOOT WITHIN 50 MSEC.
Source • System
Stimulus • Software error
Artifact • System
Env • High vehicle speed
Respons
e
• Reboot occurs
Respons
e
Measure
• Time to reboot up to 50 msec.

25. EXPLAINING ACCEPTANCE: GHERKIN
Given
Environment
• High vehicle
speed
Artifact
• System
As
Source
• System
When
Stimulus
• Software error
Then
Response
• Reboot occurs
Response
Measure
• Time to reboot up
to 50 msec.

26. IMPLEMENTATION
Gherkin stubs
Best practices
Base classes reusage
Implementation monitoring
….

27. TRACEABILITY: ACCEPTANCE TREE
1. Implementation directly linked to Quality
attribute
2. Quality attribute linked to business driver
3. Priority of the scenario shows might be a start
point for its automation

28. REAL USE CASE
Project specifics
Disk level data encryption system
Goal:
 form acceptance for the system
 Support large number of OS
 Test in the cloud
Test definitions
None
Technology
Amazon + LAMP
Resources
Senior part time and junior full time developer

29. HOW IT MIGHT LOOK IN IDE

30. DIRECT JUMP TO CODE

31. GETTING ANALYSIS DATA TOGETHER
Factor QAW-based Classic analysis approach
Work with stakeholders It’s better to have everybody in one
location, at least for a short period.
You can have several separate
sessions with technical
representatives only
Documentation That should be part of stakeholders
knowledge only
Might be outdated
Domain knowledge Not deep knowledge – participants
are the knowledge holders
Required
Rough Estimate 2-3 days 3-5 days

32. RESULT
Acceptance test suite definition (~30 tests)
Mini-framework implementation
Jenkins integration
Project was DECLINED to be released
because of NOT passing the automation tests

34. RECAP: PROCESS DEFINITION
•Break scenario into
steps
•Define steps in QC
language
•Generate test stubs
•Prioritize
•Build timeline
•Implement
•Define Business Goals
•Gather Quality
Attributes
•Generate Scenarios
Architecture
Form
Acceptance
Test solution
Trace and
update
