Verification & Validation Verification Phases – Requirements analysis – System Design – Architecture Design – Module Design Validation Phases – Unit Testing – Integration Testing – System Testing – User Acceptance Testing

Types (or Stages) of Testing (Validation) Developer Testing – Normal testing by the developer / programmer – to see it do work Independent and Stakeholder Testing – Independent Testing denotes the test design and implementation that it is most appropriate for someone independent from the team of developers to do. Unit Tests – Systematic automatic test of a unit (testing from a black box view) Integration Test – integration testing is performed to ensure that the components in combination do work (e.g. that classes across packages do work) System Test – System testing is done when the software is functioning as a whole. Do the whole system works Acceptance Test – The users do the testing and accepting as a final test action prior to deploying the software. Check that all use-cases and all non-functional requirements work

Unit testing White box testing – where you check all programming lines have been executed with an accepted result Black box testing – where you check all methods have been executed and all parameter boundaries have been checked – of cause again with an accepted result

Black-box (UPedu) input argument – Normal values from each equivalence class. – Values on the boundary of each equivalence class. – Values outside the equivalence classes. – Illegal values. output argument – Normal values from each equivalence class. – Values on the boundary for each equivalence class. – Values outside the equivalence classes. – Illegal values.
