Testing is the process of operating a program with the particular purpose of detecting errors before delivery to the end-user. Testing is a set of actions that can be planned and conducted systematically.
Software testing strategies
A strategic approach to software testing
To perform effective testing, a software Team should conduct an effective formal technical review. The test begins at the component level and works outward toward the integration of the entire component-based system. Different testing methods are relevant at different points in time. The developer of software deals with testing and may be served by independent test Groups for big projects. Testing and debugging are different actions.
Unit testing focuses verification effort on the smallest unit of software design - the software component or module. The unit testing is always white box oriented, and this step can be conducted in parallel for modules.
Unit test consideration
Unit test procedures
In order to test a single module, we have to provide a complete environment for its execution. However, is there required modules are usually not available until they too have been unit tested, stubs and drivers are designed to provide a complete environment for a module.
The role of the stub and driver module is shown below:
Integration testing strategies
During integration testing, a different module of a system of integrated using an integration plan specifies the step and order in which modules are combined to realize the full system. After each integration step, the partially integrated system is tested. The main objective of integration testing is to test the module interfaces.
A structure chart is a form of a module dependency graph. Thus, by examining the structure chart the integration plan can be developed based on any of the following approaches:
Regression testing does not relate to either unit testing, integration testing, or system testing. Instead, it is a separate dimension of these three forms of testing. Regression testing is the method of operating an old test suite after each change to the system or after each bug fix to assure that no new bug has been introduced due to the change are the bug fix.
It is an integration testing approach that is commonly used when software food products are being developed.
The smoke testing approach encompasses the following activities:
Software validation is achieved through a series of tests that demonstrate conformity with requirements
After each validation test case has been conducted one of two possible conditions exist
Software quality assurance Software quality is described as conformance to explicitly state functional and performance requirements, explicitly documented standards and implicit features that are anticipated of all professionally developer software ... Read More
A tunnel establishes a virtual pipe for data packets between a tunnel entry and a tunnel endpoint. Packets entering a tunnel are forwarded inside the tunnel leave the tunnel unchanged. Tunneling, that is, sending a packet through a tunnel, is achieved by using encapsulation ... Read More
The overall structure of the software components and how the success provides a conceptual integrated file system. In other words, architecture is the hierarchical structure of program components, how these components interact, and the structure of data that are used by the components ... Read More

Waterfall Model The waterfall model also called classic life cycle requirements is well defined and stable. It suggests a systematic, sequential approach to software development. It begins with customer specification of requirements and processes through planning, modeling, instruction, and deployment ... Read More
