 what is integration test 
(August 2010). Integration testing (sometimes called integration and testing, abbreviated I&T) is the phase in software testing in which individual software modules are combined and tested as a group.It occurs after unit testing and before validation testing. type of Big Bang Integration testing is called Usage Model testing. Usage Model Testing can be used in both software and hardware integration testing. The basis behind this type of integration testing is to run user-like workloads in integrated user-like environments. Oracle Application Testing Suite. Integration testing, also known as integration and testing (I&T), is a software development process which program units are combined and tested as groups in multiple ways. In this context, a unit is defined as the smallest testable part of an application.here are two major ways of carrying out an integration test, called the bottom-up method and the top-down method. Bottom-up integration testing begins with unit testing, followed by tests of of progressively higher-level combinations of units called modules or builds.

Bottom-up integration testing begins with unit testing, followed by tests of of progressively higher-level combinations of units called modules or builds. Integration testing is a logical extension of unit testing. In its simplest form, two units that have already been tested are combined into a component and the interface between them is tested.A component, in this sense, refers to an integrated aggregate of more than one unit. The top-down approach to integration testing requires the highest-level modules be test and integrated first. 2  This allows high-level logic and data flow to be tested early in the process and it tends to minimize the need for drivers.

Integration Testing is a level of software testing where individual units are combined and tested as a group. The purpose of this level of testing is to expose faults in the interaction between integrated units.Test drivers and test stubs are used to assist in Integration Testing. Definition by ISTQB. Bottom Up is an approach to Integration Testing where bottom level units are tested first and upper level units step by step after that. 2  This approach is taken when bottom up development approach is followed. There are two major ways of carrying out an integration test, called the bottom-up method and the top-down method.

Bottom-up integration testing begins with unit testing, followed by tests of of progressively higher-level combinations of units called modules or builds. Upon completion of unit testing, the units or modules are to be integrated which gives raise to integration testing.The purpose of integration testing is to verify the functional, performance, and reliability between the modules that are integrated.pon completion of unit testing, the units or modules are to be integrated which gives raise to integration testing. A type of Big Bang Integration testing is called Usage Model testing. Usage Model Testing can be used in both software and hardware integration testing. The basis behind this type of integration testing is to run user-like workloads in integrated user-like environments. type of Big Bang Integration testing is called Usage Model testing.

Integration testing (sometimes called the Integration and Testing, abbreviated as I and T) is one of the extensive exercises of the software testing in which particular software modules are merged and tested as a group.ntegration testing is executed to establish whether the components interact with each other consort to the specification or not. Integration testing in large refers to joining all the components resulting in the complete system. It is further performed by the developer or the software Tester or by both.
