    • Professional – Multilingual – Service Oriented Automate the Process Deliver Quality
    • Agenda  Presenter  Quality & QA  DEV Lifecycle  Cost of quality  Technical debt  Issues  Git, CI, Sonar, Se  Bottom line  Thanks
    • Ady Beleanu • Quality inquisitor • 10 years in field of QC & QA • Managed projects & teams • Coached & inspired testers • https://www.linkedin.com/in/adybeleanu
    • Quality Quality (ISO) = The totality of the characteristics of an entity that bear on its ability to satisfy stated or implied needs “= ability of product to be able to satisfy end users” The concept of making products fit for a purpose. Minimising defects and problems. You - feel it!
    • Quality Perspectives External  Valuable for users  Internal  Right design  Simple to understand  Extendable  Maintainable
    • Quality Focus – Final product  Added value  Attention to detail  Process behind the product  Innovation & Pioneering  Both – from point A to point B  the difference - usability, safety, comfort, reliability, and so on vs.
    • Quality Assurance – The Pieces For the system to work, each piece has to be:  Perfect  Easily integrated  Tested  Reusable vs.
    • Key Success Criteria THE BIBLE of the project • Business case • Architecture • Requirements • Quality strategy • Project Synchronization “Establishing your Automation Development Lifecycle”, Galen
    • Costs • Lack of Quality Management – Plan the quality – Perform QA – Perform QC • Technical DEBT • 1 External Failure Cost • 2 Internal Failure Cost • 3 Inspection (Appraisal) Cost • 4 Prevention Cost
    • Costof Quality $59.5 Billion Cost Software Errors in U.S. Economy / Year estimated $22.2 billion, could be prevented  improved testing infrastructure  eliminate defects earlier / efficiently *NIST Assessment
    • Technical DEBTf Quality http://otja.wordpress.com/2011/11/21/what-am-i- thinking-about-visualising-your-technical-debt/ GOOD code vs. BAD code or Doing it RIGHT & LONGER / QUICK & DIRTY
    • SDLC
    • Common Repository http://otja.wordpress.com/2011/11/21/what-am-i- thinking-about-visualising-your-technical-debt/ • Traceability • Visibility • Versioning • Best practices • Non-Latency • Concurrency CHAOS
    • Lack of integration http://otja.wordpress.com/2011/11/21/what-am-i-thinking-about-visualising-your-technical-debt/ Issues • Broken code check-in • Uncertainty • Missing code files • Small mistakes – BIG issues • Missing integration
    • The KEY to sustainable quality REUSE of Resources • Planning • Analysis • Design • Development • Testing • Deployment http://www.itcinfotech.com
    • A framework example
    • Repository Source Code Management (SCM) tool Version Control System (VCS)
    • Continuous Integration Automated builds Static code analysis Code coverage reports Trigger Code aggregator Central point for quality
    • Problem no.1 – Code Quality http://www.bonkersworld.net/code-reviews/ Poor unit test coverage Complexity for integration test No full regression (100%) Tight couplings
    • Why code review? Find bugs early / Fix cheap Coding standards compliance Sharing knowledge Consistent design and implementation Higher software security Team cohesion Confidence of stakeholders
    • Code Quality Measurement Needed !!! … but, WHATto measure?
    • Context – project done with & without code review:  10k LOC,  10eng,  3month project  Measured # of bugs found by QA Team in the next 6 months The result: Code review would have saved half the cost of fixing the bugs. Plus, they would have found 162 additional bugs. Code Review – Case Study
    • Code Review – Use Case
    • Code Review – Use Case
    • Code Review - trend & numbers 2012 study (VDC Research) • 17.6% software engineers surveyed currently use automated tools for CR • 23.7% expect to use them within 2 years. Capers Jones' - 12,000 SW dev projects: - 60-65% - The latent defect discovery rate of formal inspection. - < 50% - For informal inspection. - 30% - The latent defect discovery rate for most forms of testing. 150 lines of code per hour - Typical code review rates. Code reviews => ~85% defect removal rate (avg. rate of about 65%) 75% of CR defects  evolvability rather than functionality suitable for long product / system life cycles => increase of Technical DEBT.
    • Cost in SDLC
    • Code needs Continuous Inspection code violations code improvements build stability
    • Continuous Inspection with SonarQube 7 Deadly Sins of source code  Duplications  Bad distribution of complexity  Spaghetti Design  Lack of unit tests  No coding standards  Potential bugs  Not enough / too many comments
    • Integrate with SonarQube
    • SonarQube – look & feel
    • SonarQube – look & feel
    • SonarQube – look & feel
    • SonarQube – Technical DEBT Measurement
    • The so called Testing phase Functional / UI API / Services Integration Unit
    • Automated Test Tool https://saucelabs.com/tutorials/php/se2/img/Diagram-Selenium.png
    • Reporting ~20 - 40%of project lifecycle time  REPORTING
    • Simplified…
    • Bottom Line http://mycartoonthing.com/wp-content/uploads/image/business/Business%20bottom%20line%20cartoon.jpg
    • Bottom Line Harvest Foresee risks Automate & Reuse Organize process Prevent Build framework Think & Understand
