Waterfall methodology means: Figure: Structure of Waterfall method The Waterfall methodology is an approach to project management that follows a linear, sequential process. This approach is popular in software engineering and is called Software Development Lifecycle (SDLC). However, product development is also utilizing this model. The term “waterfall” refers to the flow of the project, where each phase cascades down to the next. It involves a detailed planning phase, execution, testing, and maintenance. And each phase must be completed before moving on to the next, with little to no flexibility for changes during the project. Key Characteristics of waterfall method ·        Linear and Sequential Process: The Waterfall model follows a strict sequence of phases, each dependent on the completion of the previous one. This means that you cannot move to the next phase until the current one is fully completed. ·        Di...

DevOps and its Benefits Figure: DevOps Life Cycle DevOps is a software development methodology or culture that aims to unify software development (Dev) and IT operations (Ops). It increases an organization’s ability to deliver applications and services at high velocity: evolving and improving products at a faster pace than organizations using traditional software development and infrastructure management processes. This speed enables organizations to better serve their customers and compete more effectively in the market. It emphasizes collaboration, communication, integration, automation, and continuous improvement throughout the software development lifecycle. How DevOps Works ·        Culture and Collaboration: DevOps starts with a cultural shift towards collaboration, communication, and shared responsibility between development, operations, and other stakeholders involved in the software delivery process. It promotes a culture of trust, transpar...

  Use Case Test Case Test Scenario Describes the interaction between a system and its users or external entities. A test case is a group of conditions under which a tester will determine whether the developed system is working as per the expectations or not. A test scenario is a high-level document that describes end-to-end functionality to be tested.  Provides a high-level view of how users interact with the system to achieve specific goals or tasks. Provides detailed steps and expected outcomes for executing specific tests to validate the behavior of the software. The test scenarios are those derived from the use case and give the one-line information about what to test. based on system requirements. Test cases are derived from test scenarios. Test scenarios are usually derived from documents like...

  having a detailed bug description with evidence is essential for several reasons: ·        A detailed bug description provides clear and precise information about the issue, making it easier for developers to understand the problem and take appropriate action. It reduces the chances of miscommunication or misunderstandings between testers and developers. ·        Evidence such as screenshots, videos, or log files helps developers visualize the bug and reproduce it in their development environment. This accelerates the troubleshooting process and enables quicker identification of the root cause. ·        Detailed bug descriptions help stakeholders assess the severity and impact of the issue accurately. This allows them to prioritize bug fixes based on their urgency and importance, ensuring that critical issues are addressed promptly. ·        Providing ev...

  What is Defect/Bug in software and why it is important Defects in software, commonly known as bugs, are deviations between the expected behavior of a software application and its actual behavior. These deviations can arise during various stages of the software development life cycle, from design and coding to testing and deployment. Defects can manifest as functional errors, performance issues, security vulnerabilities, or other forms of unintended behavior that negatively impact the software’s reliability and functionality. Identifying and addressing defects is a fundamental aspect of quality assurance in software development. Effective defect management ensures that software meets the specified requirements and functions reliably. Defect-free software is crucial for maintaining customer satisfaction. Users expect applications to work seamlessly without unexpected errors, and managing defects helps deliver a positive user experience. Early detection and resolution of defects...
