Custom DFE (Data Format Extension)

LoadRunner as a product has the capability to handle different data formats that are present in the communication data trace but is necessary to enable the DFE Data Format Extension option in the recording options.

Even nowadays they are more and new data formats and in this case LoadRunner its flexible and allows to develop any data format that uses the application under test by develop a new DFE in Visual Studio.

For details about how to create new DFE pleas use the developer guide located in the next path. Is necessary to install LoadRunner in order to access the guide.

Start Menu -> Programs -> HP Software -> HP LoadRunner -> Documentation -> Data Format Extensions Developer Guide

In the moment to append and add the new dll in the LoadRunner installation path and when it will be ready to use the DLL in VUGEN (Code Generation) the DLL need to be in "release" mode.

Re: Custom DFE (Data Format Extension)

Advanced LoadRunner users can create custom DFEs. For details, see the HP LoadRunner Data Format Extensions Developer Guide.

The new extension is supported in 12.53 (and further LoadRunner versions. as well).

Thanks,
