About Runtime Packages

Applies to TestComplete 15.10, last modified on December 01, 2021

Delphi and C++Builder applications can be built either with or without runtime packages. We recommend building applications for automated testing without runtime packages. This topic explains specifics of both methods.

Applications built without runtime packages

When an application is built without runtime packages, all objects and debug information are compiled into a single large .exe file. This is the recommended method, because it enables TestComplete to access all objects in the application. This ensures correct recording and playback of actions against UI controls, including complex controls such as grids and ribbons.

Applications built with runtime packages

When an application is built with runtime packages, the compiler creates separate runtime package files (.bpl). These packages contain executable code that can be accessed by any application with necessary permissions. This offers a major advantage when building extensible applications, since any extensions will also be able to use the code from these packages.

To test applications that use runtime packages:

Delphi and C++Builder provide incomplete debug information for some packages, such as vcl*.bpl and rtl*.bpl. If your tested application uses these packages, TestComplete may be unable to automate grids, ribbons and other controls in your application, because it lacks the necessary debug information. For example, TestComplete may record coordinate-based actions even if the Object Browser shows specific actions like ClickItem.

To work around the issue, do any of the following:
