  7. 7. Competences • Integration Verification • Integration of SW modules, • Planning of test approach, also coming from test plan preparation geographically distributed • Test execution on various levels: Reviews locations Module testing • Gathering quality metrics Integration testing with according to customer System testing demands • Test techniques: Specification based (functional and • Resolution of conflicts in non-functional) version control system Structure based • Support for development in Experience based problem resolving • Test strategy adjusted to development model: V-model, • Integration approach Agile, mixture... adaptation for customer needs6 © Research & Engineering Center, Wrocław, Poland
  8. 8. Verification levels Customer Product Request Acceptance Testing System System Validation Acceptance tests Requirements System Verification System Technical Solution Integration Module Testing (by developers) Test Plan System Architecture Development & Testing7 © Research and Engineering Center www.rec-global.com 2011-06-27
  9. 9. Quality first!Acceptance criteria definition - exampleWeekly criteria KPI’s – as defined by customer + REC internal Test report covering feature to be released given week Test scope: at least 30% of system requirements covered by test cases, 100% of features to be released in given weekMajor release criteria Summary of KPI’s, performed on delivery + clear statement about KPI’s for major release Test coverage: 60% of system requirements covered by test cases, 100% of features Review of test report performed by Customer Acceptance tests, performed on selected test cases – the scope must be defined before implementation starts, details to be confirmed at least 4 weeks before milestone. REC will provide compliance statement, considering available reources.Exceptions Introduced into release statement The list of missing/not executed tests should be provided. For all the cases PL’s should be awared at least 4 weeks before milestone

  11. 11. System integration – tools support Version control systems Telelogic change (together with baselines concept) SVN Clear Case Expertise: - Installation - Configuration - Maintenance - Support for geographically distributed development sites - Support for development – conflict resolution, trainings10 © Research & Engineering Center, Wrocław, Poland
  12. 12. System verification – tools support ATE (automated test environment) •Very high flexibility – python plugins allow us to adapt ATE to many different applications and communication protocols. •Detection of tool technical failures, i.e. bugs in test cases, bugs in plugins. If test case fails, it throws specific exception – „TestStepFailed”. Test case maturity levels. •Automatically generated test reports, coverage reports (like requirements coverage) •Support for various development models, including agile approach. •Automation: list of requirements, test cases (description) and test case automation (code) kept in one, consistent database.11 © Research & Engineering Center, Wrocław, Poland 2011-06-27
