330:, whereby developers may build simple to sophisticated unit and integration testing suites. The EiffelStudio AutoTest facilities enable the developer to execute and test Eiffel class code from the feature level (e.g. unit testing) to entire class systems (e.g. integration). As such, execution of this code also executes the contracts of the features and attributes executed. As such, EiffelStudio AutoTest is a means to exercising the "tests" or assumptions of the Design by Contract conditions. Therefore, unit and integration testing need not re-test through means of assertions or test oracles what has already been coded as specification in the contracts of the class text.

343:. If while running the target system, an unexpected failure occurs, EiffelStudio AutoTest can work from the information available in the debugger to create a new test that will reproduce the state and the calls that caused the failure. Once the problem is fixed, the extracted test can be added to the test suite as a hedge against regressions of the problem.

EiffelStudio traces its roots to the first implementation of Eiffel, by

EiffelStudio includes a combination of tools integrated under a single user interface: compiler, interpreter, debugger, browser, metrics tool, profiler, diagram and code inspector tool. The user interface rests on a number of specific UI paradigms, in particular "pick-and-drop" for effective
