Monkey testing is a software testing technique that involves randomly testing the application with the goal of finding defects or issues. This approach involves generating random inputs or actions and seeing how the application responds, rather than following a predefined set of test cases or scenarios.

In monkey testing, the tester does not have a specific test plan or set of test cases to follow. Instead, they use their creativity and knowledge of the software to generate random inputs or actions and observe how the software reacts. This can include randomly clicking buttons or links, entering invalid data, or performing unexpected actions to see how the software responds.
Monkey testing is often used as a complementary testing technique to other more structured testing methods, such as regression testing or functional testing. It can help identify defects or issues that may not be found through scripted testing, particularly edge cases or scenarios that may not have been considered in the test plan.
One of the key benefits of monkey testing is that it can help identify unexpected interactions or dependencies between different parts of the software. By testing the software in unexpected ways, monkey testing can help uncover issues or defects that may have been missed through more structured testing approaches.
However, it is important to note that monkey testing should not be the sole testing method used to ensure the quality and reliability of software. It is important to also use more structured testing methods, such as regression testing or functional testing, to ensure that all expected scenarios and use cases have been tested thoroughly.
In summary, monkey testing is a useful software testing technique that involves randomly testing the application to uncover defects or issues. It can be effective in identifying unexpected interactions or dependencies in the software, but should be used in conjunction with other more structured testing methods to ensure the overall quality and reliability of the software.
