SOFTWARE TESTINNG LIFE CYCLE
The Software Development Life Cycle (SDLC) is a process used by software development organizations to plan, design, develop, test, deploy, and maintain software applications. There are several reasons why organizations use the software development life cycle when developing software applications:
1. To ensure that the software is of high quality: The SDLC includes testing and quality assurance phases, which help to ensure that the software is free of bugs and that it meets the requirements.
2. To manage risks and costs: The SDLC helps organizations to identify and manage risks early in the development process, which can help to reduce costs and minimize the impact of any issues that do arise.
3. To improve communication and collaboration: The SDLC helps to ensure that all stakeholders, including customers, end-users, and developers, are involved in the development process and that their needs are taken into account.
4. To improve efficiency and productivity: The SDLC helps organizations to optimize the use of resources and to streamline the development process, which can improve efficiency and productivity.
The SDLC typically includes the following phases:

1. Requirements gathering and analysis: This phase involves gathering information about the software requirements from stakeholders, such as customers, end-users, and business analysts.
2. Design: In this phase, the software design is created, which includes the overall architecture of the software, data structures, and interfaces. It has two steps:
High-level design (HLD): It gives the architecture of software products.
Low-level design (LLD): It describes how each and every feature in the product should work and every component.
3. Implementation or coding: The design is then implemented in code, usually in several iterations, and this phase is also called as Development.
things you need to know about this phase:
This is the longest phase in SDLC model.
This phase consists of Front end + Middleware + Back-end.
In front-end: Development of coding is done even SEO settings are done.
In Middleware: They connect both the front end and back end.
In the back-end: A database is created.
4. Testing: The software is thoroughly tested to ensure that it meets the requirements and works correctly.
5. Deployment: After successful testing, The software is deployed to a production environment and made available to end-users.
6. Maintenance: This phase includes ongoing support, bug fixes, and updates to the software.
