Problem with the automatically generated file "testng-results.xml" and the UTF-8 encoding

[Daniel]

Hi,

I use TestNG togehter with Selenium, Maven, Jenkins, Cucumber and Testlink.
Because of the German special characters "ö,ä,ü,ß" my whole project has the default encoding of "Cp1252" and everything runs smoothly.

But now I got a problem with the encoding.
If I run my Cucumber Selenium tests in my Maven project via Jenkins and the "testng-results.xml" file is getting read for Testlink, I got following error, because there are some German special characters:

ERROR: An error occured while trying to retrieve the test results: hudson.util.IOException2: Failed to read C:\...\workspace\target\surefire-reports\testng-results.xml
Finished: FAILURE

The automaticly generated "testng-results.xml" file under "target/surefire-reports/" has the file encoding "UTF-8" and the first line in that file is "<?xml version="1.0" encoding="UTF-8"?>".
I guess I can resolve the problem if I find a way to change the automatically used encoding for the "testng-results.xml".

Someone knows how to do this or are there maybe other ways to solve the problem?

Daniel,

The Listener that is responsible for creating "testng-results.xml" is org.testng.reporters.XMLReporter

Within this class, inside the method org.testng.reporters.XMLReporter.generateReport(List<XmlSuite>, List<ISuite>, String)

I noticed this : rootBuffer = new XMLStringBuffer();

This is the buffer that is holding all data to be written into the above xml file.

The constructor for XMLStringBuffer() has been defined as below

  public XMLStringBuffer() {

    init(Buffer.create(), "", "1.0", "UTF-8");

  }

I guess that is why you are noticing this behavior.

So perhaps you can try something like this :

Disable the default TestNG Reporters.

Sub-class XMLReporter

override generateReport() method and modify it to suite your need.

Hope that helps

Thanks & Regards
Krishnan Mahadevan
