Difference between SDLC and STLC?
Ans: SDLC: SDLC stands for Software Development Life Cycle. It is a way to complete an Software. Every Software before publishing has to go through this Life Cycle Model. There are set of steps in Life Cycle which helps to deliver the software in specified given time. These steps includes:
Analyse customer requirements –> Design the requirements –> Code the program –> Test the Code –> Maintain and Publish.
These are some steps of SDLC. At first stage, the requirements of the customer are gathered by Business analyst of the company in the form of Business Requirement Specification. Then these are presented to the Developer team of the project. Then they start working on that as per user requirements. After that, it is forwarded to the Testing Team to check its functionality. After performing intensive testing on that and without any bugs it is sent to Maintenance team to release. These are all steps which every software has to undergo before reaching into the hands of user.
Software Testing Life Cycle (STLC)
STLC is a process of improving the quality of the software. It is executed in planned manner. It has set of steps which are helping to find the errors in the application before releasing it. The main goal of an STLC is to test the application that it is defect free so that it can perform the test as per the user requirements while it is delivered to the user.
The Stages of STLC are:
1: Requirement Analysis
2: Test Planning
3: Test Case Development
4: Environment Setup
5: Test Execution
6: Test Cycle Closure
These all steps are executed one after the other to achieve the goal of an STLC.
Each phase has some set of inputs which deliver some sort of outcomes which acts as a input to next phase.
