Definition: Black-box testing, also known as functional testing, is a testing technique that evaluates the functionality of an application without knowing the internal workings of the system. Testers focus on testing the input and output of the software, without knowing the structure, code, or architecture of the software. Characteristics of black-box testing: Focus on User Perspective: This technique mainly focuses on the inputs and outputs of the software from the user’s perspective. Tests Functionality: It tests the functionality of the software without considering how the software is designed and implemented. Independent of Programming Language: The testers don’t need to know the programming language or internal code of the software to perform black-box testing. Examples (Black-Box testing) Equivalence Partitioning: Divides input data into partitions, and one representative value is chosen from each partition for testing. Boundary Value Analysis: Focuses on testing...

Functional Testing: Functional Testing is a type of software testing where individual software components or functions are tested to ensure that they operate as expected, according to the software requirements. It focuses on testing what the system does, rather than how it works. Types of Functional Testing 1.Unit Testing Definition: Testing individual components (like classes or methods) in isolation. Purpose: Ensure each unit of the software performs as designed. 2.Integration Testing Definition: Testing how the units are interconnected and work together. Purpose: Verify that the integrated components function as expected as a whole system. 3.System Testing Definition: Testing the entire system against the system requirements. Purpose: Ensure that all components work together as expected, meeting system requirements. 4. User Acceptance Testing (UAT) Definition: Testing the system from an end-user’s perspective. Purpose: Ensure the system meets the business requirements and ...

In the dynamic world of software development, where innovation is constant and user demands evolve rapidly, the Software Development Life Cycle (SDLC) stands as a guiding framework, providing structure and coherence to the development process. In this blog post, we will delve deeper into the intricacies of the Software Development Life Cycle (SDLC). We will explore the core components and phases of SDLC, including requirement gathering, planning, design, implementation, testing, deployment, and maintenance. Additionally, we will examine different models of SDLC, such as the waterfall model, agile model, iterative model, and spiral model, highlighting their advantages and disadvantages. At its core, SDLC represents a systematic approach to building software, encompassing a series of phases and activities that ensure the creation of high-quality, reliable, and scalable applications. SDLC can be defined as a structured methodology used by software development teams to design, develop, t...

Testing is the process of evaluating a system or its component(s) with the intent to find whether it satisfies the specified requirements or not. It is the process of executing a system to identify any gaps, errors, or missing requirements in the functional, performance, and security aspects. 1.Understanding Testing Fundamentals Purpose of Testing: Ensure the quality of the software product. Validate and verify if the software product meets the business requirements. Identify and fix defects to ensure a smooth running system. Different Aspects of Testing: Functional Testing: Focuses on testing the functionality of the software. It ensures that each function or component performs the desired function accurately. Non-Functional Testing: Involves testing aspects like performance, reliability, usability, security, and more. Manual Testing: The process of testing software manually by a human tester without using any automated tools or scripts. Automated Testing: The process of testing s...

Definition Manual Testing involves the process of executing test cases or scenarios by a human, not through automated means. Manual testing is the most primitive of all testing types and helps find bugs in the software system. Any new application must be manually tested before its testing can be automated. Manual Testing Advantages 1. Exploratory Testing: Allows testers to think critically and test software from an end-user’s perspective. Helps in the discovery of defects that automated testing may not catch. 2. Unpredictable Testing: Allows the application to be tested under unpredictable scenarios. Useful in case of dynamic content and unexpected user actions. 3. Adaptability: Testers can easily adapt to changes in the software, specifications, or requirements. 4. Cost-Effectiveness: Requires fewer tools and resources than automated testing. 5. Human Judgment: Human testers can provide valuable feedback on the user interface and user experience (UI/UX) aspects of the appli...
