Unit Testing:
Verifying the functionality of individual units or components of code in isolation, typically performed by developers using test frameworks like JUnit, NUnit, or pytest.
Integration Testing:
Validating the interactions and interfaces between integrated components or systems, ensuring proper communication and data exchange, often conducted after unit testing and before system testing.
System Testing:
Evaluating the behavior of an entire system as a whole, including interactions between integrated components, to verify that it meets specified requirements and functions correctly in its intended environment.
Acceptance Testing:
Assessing whether a system meets business requirements and user expectations, typically performed by end-users or QA teams using acceptance criteria, user stories, or predefined test cases.
Regression Testing:
Ensuring that recent code changes do not adversely affect existing functionality, regression testing involves retesting previously tested features and functionalities to detect and prevent regression defects.
Performance Testing:
Evaluating the responsiveness, throughput, scalability, and stability of a system under various load conditions, including stress testing, load testing, and endurance testing, to identify performance bottlenecks and optimize system performance.
Security Testing:
Identifying vulnerabilities and ensuring the security of a system against potential threats and attacks, security testing includes activities such as penetration testing, vulnerability scanning, and security code reviews.
Usability Testing:
Assessing the usability and user-friendliness of a system or application, usability testing involves observing users as they interact with the system to identify usability issues, navigational challenges, and user experience enhancements.
Compatibility Testing:
Verifying that a system or application functions correctly across different environments, devices, browsers, and operating systems, ensuring compatibility with diverse user platforms and configurations.
Exploratory Testing:
Investigating the behavior of a system through ad-hoc and unscripted testing, allowing testers to explore and uncover defects, usability issues, and edge cases that may not be addressed by formal test cases.
Automated Testing:
Leveraging automation tools and scripts to execute tests, validate functionality, and generate test reports efficiently, improving test coverage, repeatability, and speed of testing processes.
