SIMulation Workbench
Concurrent Real-Time
Hardware-in-the-loop simulation is a trusted, cost-effective alternative for executing tests on actual equipment. It is ideal for proving designs and performing tests of complex equipment such as in automobiles, airplanes, missiles, satellites, rockets and locomotives. Testing is executed in a virtual test scenario instead of on the road or in real-devices. Much of the test environment is replaced by mathematical models, so components can be inserted into a closed loop. This makes for tests that are reproducible, systematic and fast, as well as more reliable. Concurrent hardware-in-the-loop simulation solutions feature the SIMulation Workbench real-time modeling environment running on the RedHawk Linux operating system. SIMulation Workbench provides a complete framework that makes it easy to develop and execute hardware-in-the-loop simulations in real-time. -

EasyMock
EasyMock
Most parts of a software system do not work in isolation, but collaborate with other parts to get their job done. In a lot of cases, we do not care about using real collaborators implementation in unit testing, as we trust these collaborators. Mock objects replace collaborators of the unit under test. To test a unit in isolation or mount a sufficient environment, we have to simulate the collaborators in the test. A Mock Object is a test-oriented replacement for a collaborator. It is configured to simulate the object that it replaces in a simple way. In contrast to a stub, a Mock Object also verifies whether it is used as expected. EasyMock has been the first dynamic Mock Object generator, relieving users of hand-writing Mock Objects, or generating code for them. EasyMock provides Mock Objects by generating them on the fly using Java proxy mechanism. -
