Hi Sachin,
TestComplete can be extended in two ways: via creating custom plug-ins and via script-extensions. See
TestComplete Extensions and SDK and
Creating Custom Plug-Ins.
- Plug-ins are compiled as DLLs or .NET assemblies and created with full-fledged programming languages like Visual C++, C# or Delphi. To create plug-ins, you need to download TestComplete SDK. It contains the modules required to create your own plug-ins, documentation and sample projects.
- Script extensions are more "light-weight" and simple, while being still powerful. They are created in VBScript or JScript. See the Script Extensions online topic and the Creating and Deploying Script Extensions screencast.
I'd recommend that you attempt creating script extensions for your custom components. Probably, in the from of run-time objects (similar to pre-installed WMI Object) which are added to TestComplete’s object model and displayed in the Code Completion window.
