Software testing can be categorized in various ways, depending on the criteria used. Here are some of the most common types:

1. Based on the software development lifecycle (SDLC):

• Unit Testing: This is the most basic level of testing, where individual units or modules of code are tested in isolation. This usually involves writing test cases that verify the functionality of each unit. Programmers typically perform unit testing.
• Integration Testing: After units are tested, integration testing focuses on verifying that different units work together correctly when integrated. It ensures that the interfaces and interactions between various modules are functioning as expected. Integration tests often require specialized test harnesses.
• System Testing: At this level, the entire system is tested as a whole to ensure that it meets the specified requirements and performs as expected in a real-world environment. System testing covers a broad range of aspects, including functionality, performance, security, and usability.
• Acceptance Testing: This is the final stage of testing before the software is released to end-users. It verifies whether the software meets the user's needs and requirements. Different types of acceptance testing exist, including User Acceptance Testing (UAT) and Alpha/Beta testing.

2. Based on the execution method:

• Black-box Testing: This type of testing is performed without knowledge of the internal structure or code of the software. Tests are designed based on the software's specifications and expected outputs. Examples include functional testing and UI testing.
• White-box Testing: This is also known as clear-box testing or glass-box testing. This testing method requires knowledge of the internal structure and code of the software. Testers have access to the source code and design to create tests that cover various code paths and internal workings. Techniques include code coverage analysis and mutation testing.
• Grey-box Testing: This combines aspects of black-box and white-box testing. Testers have partial knowledge of the system's internal workings but may not have complete access to the source code. This helps identify integration issues and boundary conditions.

3. Based on the testing objective:

• Functional Testing: This verifies that the software meets its specified requirements and functions as designed. This encompasses various testing types like smoke testing, sanity testing, regression testing.
• Non-Functional Testing: This assesses aspects of the software that are not related to specific functions. Examples include performance testing (load, stress, endurance), security testing, usability testing, and compatibility testing.

4. Other Notable Types:

• Regression Testing: This involves retesting the software after changes or bug fixes to ensure that the modifications haven't introduced new bugs or broken existing functionality.
