The V-model is a type of SDLC model where the process executes sequentially in a V-shape. It is also known as the Verification and Validation model. It is based on the association of a testing phase for each corresponding development stage. The development of each step is directly associated with the testing phase. The next phase starts only after completion of the previous phase i.e., for each development activity, there is a testing activity corresponding to it....

Prototyping is defined as the process of developing a working replication of a product or system that has to be engineered. It offers a small-scale facsimile of the end product and is used for obtaining customer feedback. The Prototyping concept is described below:...

The Spiral Model is one of the most important Software Development Life Cycle models. The Spiral Model is a combination of the waterfall model and the iterative model. It provides support for Risk Handling. The Spiral Model was first proposed by Barry Boehm. This article focuses on discussing the Spiral Model in detail....

The classical waterfall model is the basic software development life cycle model. It is very simple but idealistic. Earlier this model was very popular but nowadays it is not used. However, it is very important because all the other software development life cycle models are based on the classical waterfall model....

Software testing is an important process in the software development lifecycle. It involves verifying and validating that a software application is free of bugs, meets the technical requirements set by its design and development, and satisfies user requirements efficiently and effectively....

Welcome to the world of software testing, which ensures the quality and reliability of software applications. Understanding the various types of software testing is essential for developers and quality assurance professionals alike....

Extraction means “pulling out” and Retrieval means “getting back.” Information retrieval is about returning the information that is relevant for a specific query or field of interest of the user. While information extraction is more about extracting general knowledge (or relations) from a set of documents or information. Information extraction is the standard process of taking data and extracting structured information from it so that it can be used for various purposes, one of which may be in a search engine....

1. Prototype Model: The prototype model is a software development life cycle model which is used when the customer is not known completely about how the end product should be and its requirements. So in this model, a prototype of the end product is first developed by the developers and then tested and changes were made as per customer feedback until the customer is satisfied with the prototype....

Positive Testing: Positive testing is a type of software testing that is performed by assuming everything will be as expected. It is performed with the assumption that only valid and relevant things will occur. data set and all other functionalities will be as expected....

Agile Testing: Agile Testing is a type of software testing that involves all members of the project team, special experts and testers. In agile testing, testing is not a different phase and testing is performed along with development phases that includes requirements, design, coding and generation of test cases.Agile testing takes place alongside the Software Development Life Cycle (SDLC)....
