Mockito is an open source testing framework for Java released under the MIT License. [3] [4] The framework allows the creation of test double objects (mock objects) in automated unit tests for the purpose of test-driven development (TDD) or behavior-driven development (BDD).
Previous versions JUnit 4 [3] and JUnit 3 were under packages org.junit and junit.framework, respectively. A research survey performed in 2013 across 10,000 Java projects hosted on GitHub found that JUnit (in a tie with slf4j-api ) was the most commonly included external library.

Instinct [312] Behavior-driven development: Java Server-Side Testing framework (JSST) [313] Java Server-Side Testing framework which is based on the similar idea to the one of Apache CACTUS, but unlike CACTUS it's not coupled to JUnit 3.x and can be used with any testing ...
Test-driven development (TDD) is a way of writing code that involves writing an automated unit-level test case that fails, then writing just enough code to make the test pass, then refactoring both the test code and the production code, then repeating with another new test case.
For example, common values for a string are: 1) null, 2) empty, 3) whitespace (space, tabs, newline), 4) valid string, 5) invalid string, 6) single-byte string, 7) double-byte string. It may also be appropriate to use very long strings. Failure to test each possible parameter value may result in a bug.
An exception handling mechanism allows the procedure to raise an exception [2] if this precondition is violated, [1] for example if the procedure has been called on an abnormal set of arguments. The exception handling mechanism then handles the exception. [3] The precondition, and the definition of exception, is subjective.
Examples of oracles include specifications, contracts, [4] comparable products, past versions of the same product, inferences about intended or expected purpose, user or customer expectations, relevant standards, and applicable laws. Software testing is often dynamic in nature; running the software to verify actual output matches expected.
