One of TestComplete benefits is its open COM-based architecture, which lies behind its entire functionality. In fact, everything that is visible in TestComplete (panels, program objects, etc.) is implemented as plugins. For instance, support for script debugging is implemented in several dynamic link libraries that are located in <TestComplete> subfolders. TestComplete loads these DLLs when starting, so debugging looks like a built-in feature. Some of the TestComplete functionality, for instance, Unit Testing is implemented as a plugin that can be activated or deactivated (you can activate and deactivate it using the Extensions dialog). All of these plugins are located in the <TestComplete>\Bin\Extensions folder.
Of course, you can create your own plugins that fit your needs. Usually, these will encapsulate new functionality in one or several objects and expose these objects for use in scripts in the same way the Unit Testing plugin exposes the
UnitTesting object for scripting.
Using the plugins you can extend almost any subsystem of TestComplete. However, to create a plugin you need Visual Studio or Delphi programming experience.
A possible alternative to plugins is script extensions. By using script extensions you can create custom program objects and add new items to the Recording and Tools toolbars. These items can perform various tasks. For instance, they can put the tested application back to its initial state or create checkpoints. You can create these extensions by writing VBScript or JScript code.
