SDLC vs STLC
SDLC stands for “Software Development Life Cycle,” while STLC stands for “Software Testing Life Cycle.” The SDLC is a process that outlines the steps involved in the development of a software application or system, while the STLC is a process that outlines the steps involved in the testing of a software application or system.
The SDLC process typically includes the following steps:
- Planning: This involves defining the goals and objectives of the software, and creating a plan for developing it.
- Analysis: This involves gathering and analyzing information about the needs and requirements of the software.
- Design: This involves creating the design and architecture of the software.
- Implementation: This involves developing the software according to the design.
- Testing: This involves testing the software to verify that it meets the specified requirements and functions correctly.
- Deployment: This involves installing the software in its intended environment and making it available to users.
- Maintenance: This involves providing ongoing support and updates to the software.
The STLC process, on the other hand, focuses specifically on the testing phase of the SDLC. It includes the following steps:
- Planning: This involves defining the testing strategy and approach, and creating a test plan.
- Analysis: This involves reviewing the requirements and design of the software to identify the test cases that need to be developed.
- Design: This involves developing the test cases and test data.
- Execution: This involves executing the test cases and collecting the results.
- Reporting and analysis: This involves analyzing the test results and reporting any defects or issues that are identified.
- Closure: This involves reviewing the testing results, documenting any issues that were identified, and closing the testing phase.
While the SDLC and STLC processes are distinct, they are closely related and often overlap, with the STLC process being a part of the larger SDLC process.
