Product Testing

QA (Quality Assurance) Testing is the process of ensuring that a software product meets the required standards of quality before it is released to users. It involves evaluating the software to find and fix bugs, errors, or issues that could affect the user experience, functionality, or security. QA Testing is crucial for delivering reliable, efficient, and user-friendly software. Here are the main components of QA Testing:

1. Types of QA Testing:

• Manual Testing: Testing performed by a human without the assistance of tools or scripts. It involves manually executing test cases and checking whether the application behaves as expected.
• Automated Testing: The use of tools and scripts to automatically run test cases, which speeds up repetitive testing processes. Automated testing is often used for regression testing, performance testing, and load testing.

Common Tools: – Selenium – JUnit/TestNG (for Java applications) – PyTest (for Python applications) – Appium (for mobile testing)

2. Levels of Testing:

• Unit Testing: Focuses on individual components or functions of the software to ensure they work correctly. Usually done by developers using test frameworks.
• Integration Testing: Verifies that different components of the system work together as expected. This ensures that the interfaces between components are functioning properly.
• System Testing: Tests the complete system or application to ensure that it meets all functional and non-functional requirements. It’s often the final stage before the software is delivered to users.
• Acceptance Testing: Performed to verify whether the software meets the business needs and requirements. This can be User Acceptance Testing (UAT), where real users validate the software in a production-like environment.

3. Types of Testing Based on Purpose:

• Functional Testing: Ensures that the software behaves according to the specified functional requirements. This includes testing each feature against the defined specifications.
• Non-Functional Testing: Focuses on non-functional aspects such as performance, usability, reliability, and security.
