Software testing can be categorized into various types, each focusing on different aspects of the software. Here are some key types of software testing:

Testing

Unit Testing Tests individual components or functions of the software in isolation to ensure they work correctly.

Integration Testing Checks how different modules or components interact and work together.

System Testing Evaluates the complete and integrated software system to ensure it meets the specified requirements.

Acceptance Testing Verifies if the software meets the end user's needs and requirements. Includes:

Alpha Testing Conducted by internal teams before releasing the software to external users.

Beta Testing by a select group of external users to gather feedback before final release.

Non-Functional Testing

Performance Testing Assesses the software's responsiveness, stability, and scalability under various conditions. Includes:

Load Testing Checks how the system performs under a specific load.

Stress Testing Determines the system's behavior under extreme conditions or overload.

Soak Testing Evaluates system performance over an extended period.

Usability Testing Ensures the software is user-friendly, intuitive, and easy to use.

Security Testing Identifies vulnerabilities, threats, and risks in the software to ensure data protection and security.

Compatibility Testing Checks the software’s compatibility with different operating systems, browsers, and devices.

White-Box Testing

Static Testing Involves reviewing the code and software documentation without executing the code. Includes code reviews and static analysis.

Dynamic Testing Tests the software while it is running, focusing on its execution paths, data flow, and control flow.

Black-Box Testing

Boundary Value Analysis Tests the software using boundary values of input data to identify edge cases.

Equivalence Partitioning Divides input data into equivalent partitions to reduce the number of test cases.

Exploratory Testing

Ad-Hoc Testing Involves testers exploring the software without predefined test cases, often discovering issues through informal testing.

Re-testing Tests the software after fixes or changes to ensure that previously working functionality has not been broken.

Regression Testing Verifies that new code changes have not adversely affected existing functionality.

End-to-End Testing

Scenario Testing Validates the complete workflow or business process from start to finish to ensure it behaves as expected.

Testing

Sanity Testing Conducts preliminary tests to ensure the software build is stable enough for further testing.

User Interface Testing

GUI Testing Checks the graphical user interface for consistency, alignment, and functionality.

Each type of testing serves a specific purpose and contributes to ensuring the overall quality and reliability of the software.
