Software testing is the process of evaluating a software item to identify differences between given input and expected output. It also confirms that the feature and functions of the software going to be working according to the specifications and requirements. It is considered as most important part of software development cycle(SDLC). Testing actually defines the quality of the product. Software testing is a process which should be done during the development process and the system is complete.
Devising a data conversion strategy and a changeover for TIMS must include the design plan, post-implementation appraisal, fact assembly, topics to cover, and who should accomplish it. Integration Integration testing comes before system testing and after unit testing has been completed. The integration testing stage will make developers aware of any errors produced due to the system or the script. The integration testing phase seeks to confirm that the integration of the components is fruitful and that it runs effectively, devise a test plan, and collect test case data produced to efficiently test that the integration is efficacious. Integration Test Plan When creating a test plan it must include the following information, Testing modules and how the tests will be accompanied.
The Main purpose of testing is to check that software meets all specified requirements that guided its design and development. There are many types of software testing techniques that can be performed with in software development life cycle. Out of many software testing techniques, Acceptance testing (AT) is the key feature of software implementation. As the acceptance testing mainly constituents that the system should be acceptable by its owner or user it is also called as User Acceptance Testing (UAT). UAT is performed to ensure that the new system meets all the essential user requirements.
The precise requirement can be considered as testable requirement. A testable requirement should be able to tested by one or more test cases. ... ... middle of paper ... ...se requirement can be identified if the requirement can be tested by one or more test cases. This is a vague statement and need more clarity. Overall the author has defined the testable requirements for sizing project well however it needs to be improved with more clarity and details.
This will enable the user to realize the problems faced by software testers and the importance of software testing. Software testing is the “process of executing a software system to determine whether it matches its specification and executes in its intended environment” (Whittaker 71). It is often associated with locating bugs, program defects, faults in the source code, which cause failures during execution that need to be removed from the program. Locating and removing these defects is called debugging, which is different from the testing that establishes the existence of these defects. Specifications are crucial to testing because they identify correct behavior so that software failures corresponding to incorrect behavior can be identified.
Software Validation and Verification A. Concepts and Definitions Software Verification and Validation (V&V) is the process of ensuring that software being developed or changed will satisfy functional and other requirements (validation) and each step in the process of building the software yields the right products (verification). The differences between verification and validation are unimportant except to the theorist; practitioners use the term V&V to refer to all of the activities that are aimed at making sure the software will function as required. V&V is intended to be a systematic and technical evaluation of software and associated products of the development and maintenance processes. Reviews and tests are done at the end of each phase of the development process to ensure software requirements are complete and testable and that design, code, documentation, and data satisfy those requirements.

The two methods are explained below: 5.9.1 Analysis of Qualitative Data There are a variety of suitable analytical approaches to qualitative research and many of them can be aided with computer software [Marshall and Rossman (1989); Coffy and Atkinson (1996]). It would be wrong for qualitative research to apply the available software to drive the general research strategy (Berger, 2006). The decision is to be taken weather to analyse data with the aid of a software computer package (e.g. QSR NVivo 10 etc.) or manually.
