Software Testing

Waterfall Model: Water fall model is a traditional model for software development life cycle(SDLC). It is considered as classic development model. This model describes the development method in linear and sequential manner.  This type of development is having a distinct goal for each phase. It is the one-way development process. If the development of one phase is over then only we can switch for next phase and there is no turning point for go back. The image shown here is regarding the process of waterfall model which shows us the flow of life cycle for a system.  In waterfall model we follow the following phases: Project Planning Requirement Collection Feasible Study Design HLD(High Level Design) LLD(Low Level Design) Development Testing Installation/Acceptance Maintenance                -------------------------------------------------------------------------------- Brief of all the phases Project Planning In this phase, the basic planning for project will takes place.

SDLC Software Development Life Cycle (or) it is also known as "System Development Life Cycle". SDLC is a procedure through which a software can be developed.  With the help of this process we can create or alter the system and models along with the methodology which is helpful for developing these system/software/app . The result of any SDLC in high quality system is that to meet or exceeds customer expectations, should reach completion with time and cost estimation, will work effectively and efficiently and should be inexpensive for maintain along with cost effective to change. The SDLC concept is usually applies on the range of software and hardware configuration, as a system can be composed of only hardware, only software or a combination of both. Phases of SDLC : - Primary Analysis In this step we are trying to find out the objective of organization's and nature and scope of the problem which is under study.   System Analysis and Requirement Definition In this
