Some commonly used software testing techniques are:

1. Black Box Testing: Testing the software without any knowledge of its internal structure or implementation.
2. White Box Testing: Testing the software with knowledge of its internal structure and implementation.
3. Grey Box Testing: Combining elements of both black box and white box testing approaches.
4. Equivalence Partitioning: Dividing input data into classes to reduce the number of test cases required.
5. Boundary Value Analysis: Testing at the boundaries of input ranges to uncover defects.
6. Regression Testing: Repeating tests on modified parts of the software to ensure existing functionality is not affected.
7. Exploratory Testing: Informal testing approach where testers explore the software without predefined test cases.
