What is SDLC?

SDLC is a process followed for a software project, within a software organization. It consists of a detailed plan describing how to develop, maintain, replace and alter or enhance specific software. The life cycle defines a methodology for improving the quality of software and the overall development process.




1. Requirement Gathering and Analysis

This is where the team collects all the details about what the users and stakeholders want from the software. They analyze these needs to understand exactly what the system should do.

2. System Design

Based on the requirements, designers create the architecture and detailed plan for how the software will work. This includes designing the user interface, system components, and data flow.

3. Implementation (Coding)

Developers write the actual code according to the design documents. This is when the software is built piece by piece.

4. Testing

The software is tested to find and fix bugs or errors. Testers check if the software meets the requirements and works correctly in different scenarios.

5. Deployment

Once testing is complete and the software is stable, it is released to users. This can mean installing it on user systems or making it available online.

6. Maintenance

After deployment, the software is maintained and updated to fix any new issues, improve performance, or add new features based on user feedback.

The Software Development Life Cycle (SDLC) is important because it provides a solid foundation for planning, scheduling, and estimating projects. It creates a standard framework of activities and deliverables that everyone can follow, making it easier to track and control progress. SDLC also improves transparency, so all stakeholders stay informed throughout the process. By following SDLC, development becomes faster, client relationships improve, and everyone involved—from developers to management—can better contribute to the project’s success.

Non-Functional Testing

-
Non-Functional Testing Non-functional testing  is an important part of software testing that checks how well the system works rather than what it does. It focuses on quality aspects like  performance ,  security ,  usability , and  reliability  to ensure the software is stable, efficient, and ready for users. Types of Non Functional Testing in Software Testing Non-functional testing types encompass a broad spectrum of testing types, each evaluating the software’s performance and usability. 1. Performance Testing Assess how fast and responsive the application is under different conditions. It measures metrics like response time, load time, and throughput to ensure smooth operation under typical usage. 2. Load Testing Simulates expected user traffic or transaction levels to check for performance bottlenecks. This helps identify whether the application can handle the anticipated load before going live. 3. Stress Testing Pushes the system well beyond normal ope...

Black Box Testing and White Box Testing

-
Black Box Testing and White Box Testing Black box and white box testing are distinct methodologies with opposing objectives. However, they can complement each other to improve testing effectiveness. Black box testing evaluates an application from the user's perspective, while white box testing examines the code and internal design. Black box Testing Black box testing  is a way of testing software without looking at its internal code or design. Testers check if the software works as expected by using the requirements and specifications. They enter data, watch the outputs, and see how the system responds, including how fast and reliable it is. This method can be used at many levels of testing, like unit, integration, system, and acceptance testing, but it’s mostly used in higher-level tests. Testers don’t need coding knowledge—they just focus on whether the software does what it should from the user’s perspective. It’s also called specification-based testing or closed box testing bec...

Use case vs Test Case

-
Use case vs Test Case What is a Use Case? A  use case  is a common concept in software development that explains how a user interacts with a system to achieve a specific goal. It shows step-by-step what happens during the interaction, including inputs, outputs, and expected behavior. Use cases can be written as text or shown in diagrams, helping teams understand what the system should do from the user's point of view. What is a Test Case? A  test case  is a set of instructions created by testers to check if a specific feature or function of a software application works correctly. It includes the test inputs, conditions, and the expected results. Test cases help find bugs and ensure the software is reliable and meets the requirements. Each test case should be clear, linked to the correct feature, and well-documented. Managing test cases properly is key to successful testing and delivering a high-quality product. Difference between Use Case and Test Case Use case Test ...
