What are the Differences Between SDLC and STLC?
As we have seen a fleeting introduction to SDLC and STLC. Now we will study the difference between SDLC and STLC. The notable differences between these two software development cycles are described in the table provided below:
Key Differences Between SDLC and STLC
Difference Between SDLC vs STLC
SDLC is generally related to software development.
STLC is generally related to software testing.
Including the development, it focuses on other phases like testing are also included.
STLC focuses only on testing the software.
SDLC consist of a total of six steps or phases.
STLC consist of only five phases or steps.
In this more members (developers) are required for completing the whole process.
In this, less number of members (testers) are needed for completing the whole process.
The development team makes the whole plans and designs.
The testing team makes the whole plans and designs.
The objective of SDLC is to complete the successful development of software.
The objective of STLC is to complete the successful testing of software.
SDLC helps in developing good quality software.
STLC helps in making the software defects/error-free.
These phases are completed before the STLC phases.
These phases are performed after the SDLC phases.
What is the SDLC?
The term SDLC stands for Software Development Life Cycle it describes the process of several activities followed by the software industry to bear working software. It brings about planning, requirement gathering, analysis, designing, implementation, testing, and maintenance. SDLC covers the entire life cycle of software, such as its formation to its retirement. The SDLC life cycle consists of a few phases, each one has its processes and deliverables. The result of the given process should be a software system that fulfils the customer expectations like the work process should be completed within the estimated time and budget, etc.
A flowchart of SDLC that has a sequence of different activities performed during the software development process is given below:
Requirement Analysis ➡ Software Design s ➡ Software Build ➡ Testing ➡ Deployment ➡ Maintenance.
What is the STLC?
The term STLC stands for Software Testing Life Cycle. It consists of a series of few activities to assure the quality of the software application as a segment of the testing process. This cycle is performed by the testing team to assure the software is of high quality and also ensure that each new function should roll out smoothly and successfully. STLC is an integral part of the SDLC but only applicable to the testing phases. The phases of STLC may be replicated multiple times during product development. The test closure is a document that is provided for the analysis of all tests conducted during the software development life cycle.
A flowchart of STLC that has a is a sequence of different activities processed during the software testing process is given below:
Test Planning ➡ Test Case Development ➡ Test Environment Setup ➡ Test Execution ➡ Test Closure.
