What is SDLC?

SDLC (Software Development Life Cycle) is a term that refers to all of the normal phases of the software development process. The SDLC life cycle is a staggered approach to software development that follows the steps below.

  1. Requirements Gathering
  2. Design the software
  3. Build the Software
  4. Test
  5. Deployment
  6. Maintenance.

There are specific entry and exit requirements, as well as deliverables, for each level.

What is STLC?

The Software Testing Life Cycle (STLC) refers to a well-designed testing process in which different activities are completed in order to improve the product’s performance. The STLC phases, on the other hand, only deal with testing and detecting errors, not with progress.

The generic Software Test Life Cycle, on the other hand, has the stages mentioned below.

  1. Requirement Analysis
  2. Test Planning
  3. Development
  4. Environment Setup
  5. Execution & Closure


  • The SDLC process specifies all of the normal processes that occur during the software development process, while the STLC process defines different activities that enhance the product’s quality.
  • The SDLC stands for Software Development Life Cycle, while the STLC stands for Software Testing Life Cycle.
  • The development team develops high and low-level design plans in the SDLC, while the test analyst creates the System, Integration Test Plan in the STLC.
  • The SDLC life cycle assists a team in successfully completing software development, while the STLC phases only cover software testing.

Why Use SDLC?

Here, are some prime reasons for using SDLC method:

  • Its goal is to create a high-quality software system that will assist you in exceeding customer expectations.
  • SDLC aids in the development of extensive machine documentation.
  • It generates a large number of intermediate products that can be examined to see whether they can satisfy the user’s needs and are compliant with the specified requirements.
  • Each process has its own set of deliverables, as well as entry and exit requirements.
  • The development phases are completed one by one, which is an excellent option for small to mid-sized projects with well-defined specifications.

Why Use STLC?

Here, are Important reasons for using STLC method:

  • STLC contributes to a more sophisticated, reliable, and efficient testing process.
  • For each stage of the project, you should provide milestones and deliverables.
  • Even when the model is expanded to several stages, it remains easy to comprehend and implement.
  • Plan formulation has strict time constraints.
  • Each project module is thoroughly tested before moving on to the next.
  • The project’s requirements are weighed against the real outcome.

Features of SDLC

  • The structure and functions of the model are well known, and the tested outcome is easily accessible.
  • Before starting another project, the project may be completed in stages. The project units are distinct and easy to recognize.
  • Risk management is an important part of the model, and it is well-managed.
  • The project can be structured in such a way that the components are sourced.

Features of STLC

  • STLC examines client and stakeholder criteria for the framework.
  • Assists you in establishing traceability of the Matrix.
  • Determine the research methodology and forms.
  • Prioritize the function that should be the focus of the evaluation.
  • STLC may be used to assess the automation feasibility.
  • Determine the details of the laboratory environment in which the actual test should be run.
