Monkey testing is a type of Black Box Testing used mostly at the Unit Level. In this tester enter the data in any format and check the software is not crashing. In this testing we use Smart monkey and Dumb monkey.

- Smart monkeys are used for load and stress testing, they will help in finding the bugs. They are very expensive to develop.

- Dumb monkey, they are important for basic testing. They help in finding those bugs which are having high severity. Dumb monkey are less expensive as compare to Smart monkeys.
