Software And Software Based Systems Testing

The Verification and Validation, or V-model, Software Development Paradigm will be used to define the development life cycle of the software product. This paradigm was chosen because it allows us to test the software during each stage of the project in an inverse way. Also, because the validation and verification of

A: In the software lifecycle there are 4 phases that are derived from the old System Development Life Cycle (SDLC) and they are as follow; Planning, Implementation, Maintenance, and the Removal process. The planning phase is defined by all planning activities including the analysis of the software to be installed, verification of its compatibility, supported methods of installations, and the identification of any risks associated with the software and the desired deployment method. The Implementation phase is used to prepare for deployment such as; creating a shared access location for files and creating or using the appropriate package files. After all these steps have been

Once requirements are analyzed the designing of the system starts based on the requirements gathered from the client. After the designing of the system is done implementation takes place followed by testing. If the testing is complemented and no false results are found, the project is deployed and last but not the least maintenance of the project is done as and when required based on the discussions with the client.

4. Development and Testing – This step involves using the final system design to acquire or develop the system. Testing of units, integration, performance, system, and acceptance are done to ensure system functionality and the sponsor’s requirements and that all segments/structures, communications, applications, procedures, and documentation are in place, tested, and integrated. End users are implemented to verify and thoroughly test that the system functions as required.

The tests and the procedure by which testing is performed and results reviewed and addressed, must ensure that the system is compliant with business rules, meets the users ' expectations, and performs as expected in the actual business environment. [28]

Six years of experience in Application Analysis and Quality Assurance Testing of application systems coupled with Strong Database Knowledge in Client/Server and Web and database environment.

Software testing refers to the process of finding an error of ensuring that particular software meets its specification. The growing complexity of software division into various application demands highly skilled engineers with the appropriate mix of expertise. Testers need to do sampling such as generates a set of test cases to validate against the user

Testing can be stated as the process of verifying and validating that a computer program, application or product meets the requirements according to the proposed design and development.

Software Development Life Cycle, (SDLC) denotes the process used by software industries to design, develop and test high-quality software. SDLC is also referred to as Software development process and aims at producing high-quality software meeting or exceeding customer’s expectations, or that reaches completion within cost and times estimation. A system is a set of intermingling or dependent components that form a unified whole; it is a term that can get used in diverse industries. Therefore, SDLC is a limited term that explains the phases of developing a software component integrating with other software constituents to develop the whole system. Software Development Life Cycle depicts the process to be followed by a software organization for a software project consisting of the detailed plan with a description of how to develop, maintain, alter, and replace a particular software (Davis et al. 1455). Typically, an SDLC consists of six development stages as listed below:

Software implementation and deployment – this is where the actual coding and series of testing of the system takes place. A final system is built basing on the prototype built earlier. After which the system will be ready to be installed and used by the user. Series of system testing is done to verify full functionalities of the system before deploying to avoid errors in the user side.

Software testing is used to identify the precision extensiveness and quality of development software. It also includes the sets of activities. Software testing is an activity to check the expected outcome from the software so that it is really used to make the software proper and perfect. Software testing is used to minimize the errors, gaps, missing requirements in the software and make proper development in the software so that it hold the values in the market and to gain more popularity in the market of computing.

The testing discipline includes activities that verify correct functioning of infrastructure and application software components.

Software testing is one type of process that should be always done during the software development process.
