Unit Test vs Integration Testing. • The ideal in unit testing is to isolate a single code unit and test it against its behavioural specification. • This may involve the construction of extensive 'scaffolding' code that allows the tests to proceed. In particular the tester needs to construct: – Driver code to drive the code unit. This is
26 Nov 2004 A unit is the smallest testable piece of software. A unit is defined as a database trigger, stored procedure, function, report, form, batch load program or PL/SQL program. ? Unit testing is the testing that is performed to validate that the unit does satisfy its functional specification and/or that its implementation
Abstract—System integration testing is the process of testing a system by the stepwise integration of sub-components. Usually these sub-components are already verified to guarantee their correct functional behavior. By integration of these verified sub- components into the overall system, emergent behavior may occur, i.e.
Integration Testing, a software testing discipline that focusses on testing the interfaces of the modules as well as their interactions However, we distinguish Integration Testing from E2E or System testing by the fact that E2E tests try to verify detailed . l_reports/SoftwareDevelopment-Fraunhofer_SIT.pdf. About The Testing
INT–2. Integration Testing. ?. Test the interfaces and interactions among separately tested units. ?. Three different approaches. ?. Based on functional decomposition. ?. Based on call graphs. ?. Based on paths
An integration strategy must answer three questions. 0 Which components are the focus of integration test? 0 In what sequence will component interfaces be exercised? 0 Which test design technique should be used to exercise each interface?
Strategies in Integration Testing. ? The top-down approach to integration testing requires the highest-level modules be tested and integrated first. ? The bottom-up approach requires the lowest- level units be tested and integrated first. ? The sandwich approach combines the top- down approach and the bottom-up
31 Jan 2013 Integration testing focuses on interactions. – Must be built on foundation of thorough unit testing. – Integration faults often traceable to incomplete or misunderstood interface specifications. •Prefer prevention to detection, and make detection easier by imposing design constraints. • Strategies tied to project
12 Jan 2007 In this document, we will discuss one of the testing phase, integration testing, and its different strategies. Namely decomposition-based integration, call-graph based integration and path-based integration. We will see that for each strategy there are different approaches to achieve the same main concept but
