Testing a Transformation Program
You use this procedure to test XSLT transformation programs.
You can use the test environment only for activated XSLT programs.

It is not possible to test programs that result in an ABAP data structure.
...
1. In the Object Navigator (transaction SE80), open the transformation program you need.
2.
In the
application toolbar, choose
with the quick info text Test XSLT Program
or press F8
to start the test environment.
The XSLT Tester screen appears.
3. Specify the path for uploading the XML source document.
4. Specify the output of the transformation.
The following options are available:
○ String output: The system transforms the result into a string and displays it as a simple list.
○ File output: The system saves the result as a local file. You need to specify the path for the output file in the Result File Path field.
○ Document output: The system transforms the result into a DOM tree, then displays the DOM tree using iXML methods, and in the end displays it as a list.

In this case, the settings for XSLT output have no effect.
○ HTML view: The result is displayed in a browser.
5. Choose Execute to execute the transformation.
