Questions tagged [jmockit]

JMockit is a java framework for mocking objects in JUnit testing. It uses the instrumentation apis that modify the bytecode during run time to dynamically create classes. It allows developers to write unit tests without the testability issues typically found with other mocking APIs. Tests can be written that will mock final classes, static methods, constructors, and so on. The API also provides advanced support for integration tests and code coverage tool.
