DUnit
Encyclopedia
DUnit is an automated unit test
ing framework for Borland Delphi
. DUnit allows Delphi (Object Pascal
) developers to use test-driven development
.
DUnit's original code was written by Juanco Anez and is based on JUnit
by Kent Beck and Erich Gamma.
Several developers now maintain DUnit as a project on SourceForge
.
DUnit became a standard part of Delphi starting with Delphi 2005. Two key files provide most of the test framework functionality: TestFramework.pas and GUITestRunner.pas.

Unit test
In computer programming, unit testing is a method by which individual units of source code are tested to determine if they are fit for use.A unit is the smallest testable part of an application. In procedural programming a unit could be an entire module but is more commonly an individual function...

Test-driven development
Test-driven development is a software development process that relies on the repetition of a very short development cycle: first the developer writes a failing automated test case that defines a desired improvement or new function, then produces code to pass that test and finally refactors the new...

DUnit extensions
PascalMock provide an extension to DUnit with the class TMockObjectTestCase which allow to easily use Mock objectMock object
In object-oriented programming, mock objects are simulated objects that mimic the behavior of real objects in controlled ways. A programmer typically creates a mock object to test the behavior of some other object, in much the same way that a car designer uses a crash test dummy to simulate the...
