Software Development Life Cycle (SDLC) is a systematic process used to develop, deliver high-quality software applications. It encompasses a set of phases, activities, and deliverable that guide the development team from initial concept to the final product release and maintenance. Common phases and significance of SDLC: 1. Requirements Gathering: In this phase, project stakeholders and developers collaborate to understand software requirements, user needs, and business objectives. This phase is to establish a clear understanding of the project scope, goals, and deliverable, which helps in planning subsequent activities effectively. 2. System Analysis: sys tem anal ysis phase involves analyzing gathered requirements to define application functional and non-functional specifications. It helps identify potential challenges, dependencies and technical feasibility, allowing the team to make informed decisions about software architecture design. 3. Design: The design phase focuses on trans...

Software testing is a process that is followed in development and maintenance of software application. It involves assessing the quality, functionality, and performance of a software application to identify any defects, bugs, or errors. The objective of software testing is to make sure the software application meets the received requirements, functions as intended, and delivers a good user experience. Software testing majorly classified into two categories: 1. Functional Testing – which mainly focuses on functionality validation and making sure it meets the                requirement.       Ex : Unit Testing, Smoke Testing , System Testing, Integration Testing, User Acceptance Testing. 2. Non-Functional Testing – which focuses on non-functional aspects like performance, security, resiliency of software application.     Ex : Performance Testing, Security Testing, Fail-over Testing, Compatibility Testing. Why...

Software testing lifecycle (STLC) is a process of testing software applications or systems to ensure that it meets quality, reliability, and functionality.  It consists of several phases that help identify and resolve defects or issues before the software is made available to the external customer (i.e Production) .   The following are the typical phases involved in the software testing lifecycle: Requirement Analysis : In this phase, testers review the software requirements and specifications to gain a clear understanding of the expected behavior and functionality of application. It helps identify potential test scenarios and ensures that the testing process aligns with the project goals. Test Planning : Test planning involves creating a comprehensive test plan that outlines the testing approach, objectives, scope, test environments, resources, and schedules. It identifies the types of tests to be conducted and defines the entry and exit criteria for each test phase. Te...

Functional testing is a kind of software testing that focuses on verification of the functional requirements and specifications of a software application.  It aims to ensure that the application's features and functionalities work as intended and meet the user's expectations. Functional testing examines the system's behavior by testing individual functions or components and their interactions within the larger system. The significance of functional testing lies in its ability to: 1. Validate Requirements : Functional testing helps validate that the software application meets the specified requirements. By testing each function or feature, it ensures that they perform correctly and deliver the expected results. 2. Detect Defects and Bugs : Functional testing helps identify defects, bugs, or errors in the software application. By executing test cases and comparing actual results against expected outcomes, testers can uncover issues and report them to the development team for ...

 Non-functional testing is a type of software testing that focuses on evaluating the non-functional aspects of a system rather than its specific functionalities. It is performed to assess the performance, reliability, usability, scalability, and other quality attributes of a software application or system. The primary goal of non-functional testing is to ensure that the software meets the desired levels of performance, usability, and other non-functional requirements. Here are some key aspects and significance of non-functional testing: 1. Performance: Non-functional testing helps identify how well a system performs under specific conditions, such as high load, stress, or concurrent user access. It aims to uncover performance bottlenecks and determine if the system meets response time, throughput, and resource utilization requirements. 2. Reliability: This testing evaluates the system's stability and ability to perform consistently over time. It includes testing for fault tolerance...

 Non-functional testing involves evaluating the performance, reliability, usability, security, and other non-functional aspects of a software application. Some common types of non-functional testing: 1. Performance Testing: This type of testing assesses the responsiveness, scalability, and stability of a system under different load conditions. It includes tests like load testing, stress testing, endurance testing, and scalability testing to identify performance bottlenecks and ensure the system meets performance requirements. 2. Load Testing: Load testing measures a system's performance under expected user loads to determine its capacity limits and response times. It helps identify performance degradation, resource utilization issues, and potential bottlenecks when multiple users access the system simultaneously. 3. Stress Testing: Stress testing evaluates the system's behavior under extreme conditions, such as high user loads, limited resources, or unfavorable environmental fa...

 Functional testing is a type of software testing that focuses on verifying the functional requirements and specifications of a software application. It ensures that the system behaves as expected and meets the intended functionality. Here are some common types of functional testing: 1. Unit Testing: Unit testing focuses on evaluating individual components or units of the software, such as functions, methods, or classes, in isolation. It verifies the correctness of each unit's behavior and ensures that they function as intended. 2. Integration Testing: Integration testing checks the interaction and communication between different modules or components of the software. It validates the integration points, data flow, and interfaces to ensure that the system functions correctly as a whole. 3. System Testing: System testing assesses the fully integrated software system to ensure it meets the specified requirements. It verifies the system's behavior, functionality, and performance i...
