The main difference between SDLC and STLC is that the SDLC is a process followed by software organizations to deliver a working software to the end users which involves planning, requirement gathering, and analysis, designing, implementing, testing and maintenance. Whereas, the STLC is a process followed by the testing team to ensure the quality of the software, which only involves software testing.
Software Development is a complicated process. Even though it is simple and easier to develop a small program, it is quite difficult to build enterprise level software. Therefore, it is necessary to use a proper methodology to develop the product. SDLC is the process used by software organizations to deliver working quality software to end users.
It covers the entire life cycle of the software. On the other hand, STLC is the process of following the activities to ensure the quality of the software. It is a process followed from start to the delivering the software to the production environment.
There are various phases in SDLC. This also includes recognizing risks, technical difficulties, resources. Meeting the customer, meeting senior managers, observing the sales and marketing details are some of them. Then, the gathered information is analyzed and documented. It contains the requirements that need to designed and developed during the life cycle of the project.
Designing — This phase involves designing all the architectural modules, data flow representations with other modules. It also involves database designing, class diagrams, and object diagrams designing. It involves selecting programming languages, Integrated Development Environments IDE and tools such as code editors, debuggers, etc. There are two types of testing called functional testing and nonfunctional testing.
Functional testing checks the functionalities of the software while nonfunctional testing checks the nonfunctional aspects such as performance, load, usability, etc.
Deployment and Maintenance — Finally, the product is released to the market. According to the customer feedback etc. The technical support teams provide the required services to maintain the software. This phase is also called evolution.
It is the process followed by the testing team to produce a quality software at the end. The testing team prepares the test cases and start executing them to find defects of the software. STLC involves following different phases. It is not mandatory to follow all of them.
The phases in STLC can depend on the type of software, available resources and time for testing, requirements of the organization, etc.
Requirement Analysis — After preparing the SRS document, the testing team starts a high-level requirement analysis. Test Planning — This phase is to plan the strategies and approaches for testing. Test Case Designing — It involves developing test cases. A test case is a set of actions executed to verify a particular feature or a functionality of the software.
Test Environment Setup — It is the phase in which the integrated environment is ready to validate the product. Test Execution — This phase performs real-time validation of the software. It actually finds the defects. Test Closure — After completing testing, the test results are documented. SDLC is the process followed by the development team within the software organization to develop a software product.
STLC is the process of carrying out various activities to ensure the quality of the software. Furthermore, in SDLC, business analyst gathers requirements and the development team analyzes them. They consider the architecture and design. In SDLC, designing involves developing high-level and low-level design of the software according to requirements. In STLC, designing is performed by the test architect or a test lead. He plans the test strategies to identify testing points.
In SDLC, development team starts developing the software in the development phase. In STLC, the testing team writes test scenarios to validate the quality of the software.
They write test cases for all modules with the expected outputs. In SDLC, the testing such as unit testing, integrated testing, system testing etc. The test report is sent to the developers. They fix the defects and sends it back to the testing team for retesting. Moreover, in SDLC, after the testing phase, the software is released to the real end users.
In STLC, smoke and sanity testing are performed after deploying the software. Furthermore, test reports, matrixes and other documents are prepared by the testing team. In SDLC, the technical team provides support to update and maintain the software.
In STLC, the test cases and automation scripts are maintained for updates. SDLC is the process followed by the software organization to deliver a working software to the end users which involves planning, requirement gathering, and analysis, designing, implementing, testing and maintenance. STLC is the process followed by the testing team to ensure the quality of the software, which only involves software testing.
She is passionate about sharing her knowldge in the areas of programming, data science, and computer systems. Figure 1: SDLC. Figure 2: Testing Types. View all posts. Leave a Reply Cancel reply.
