The Unified Modeling Language (UML) is a standardized visual modeling language used to design, specify, construct, and document software systems. Elaboration: Example (Class Diagram): A UML class diagram representing a Bank Account system: +——————+| BankAccount |+——————+| -accountNumber || -balance |+——————+| +deposit() || +withdraw() |+——————+
A Use Case Diagram is a UML diagram that represents interactions between users and a system. Elaboration: Example: A Login System use case diagram includes User (actor), Login Process, and Authentication System.
SRS is a document that defines the functional and non-functional requirements of a software project. Elaboration: Example: An SRS for a hospital management system details appointment scheduling, patient records, and billing.
Regression Testing checks if new code changes have broken existing functionalities. Elaboration: Example: Running automated Selenium tests after updating an e-commerce checkout system.
Acceptance Testing ensures software meets business requirements and is ready for end-user deployment. Elaboration: Example: A client tests CRM software before rolling it out to sales teams.
System Testing evaluates the entire software application as a whole to verify compliance with requirements. Elaboration: Example: Testing a banking application across different operating systems before deployment.
Integration Testing verifies that different components/modules of a system work together correctly. Elaboration: Example: Testing API communication between a payment gateway and an e-commerce website.
Unit Testing involves testing individual components (functions, modules) of a software application in isolation. Elaboration: Example (Python Unit Test using PyTest): add(a, b): return a + bdef test_add(): assert add(2, 3) == 5
Software testing is the process of evaluating software to ensure it functions correctly and meets user requirements. Elaboration: Example: A team uses Selenium automation testing to verify a web application’s functionality before launch.
DevOps is a software development practice that combines development and IT operations to enable continuous integration and delivery (CI/CD). Elaboration: Example: A cloud-based SaaS company implements DevOps to deploy updates multiple times a day.
