• Human made

Phase of STLC –

As we already discussed about “What is STLC” in previous post. Here is the brief understanding of the phases/stages/processes of STLC –

Phases of Software Testing Life Cycle-

What is STLC – Software Testing Life Cycle ?

STLC – Software Testing Life Cycle

STLC defines the life cycle or phases of testing process for a software or a system/application. It tells the planned and systematic process of execution to improve and deliver a quality product.

Although all three are interrelated and same up to some extent apart from this all together these terms are related and work together to deliver a quality product/service, but all are the different processes.

What is SDLC – Software Development Life Cyclen

What is SDLC –

This is a software engineering term also called software or application development life cycle.
The term is use to describe the life cycle or phases of development procedure for a software/system/application.

Importance of Software Testing

Although software testing is  just a phase of SDLC but due to the importance now it is included in all phases to improve the quality of software development.

Software Testing is important because of the following reasons –

• To satisfy the software requirements

Who perform the Testing ?

The answer is simple “It depends”

Depends on company to company, project to project, Requirement to requirement.

Usually there was a time when testing was done by the developer for the code written by him which was debugging, as we discussed in previous posts.
