The below error occurs when the property ‘Encoding’, which is used for reading the test files is commented.
`Exception in thread “main” java.lang.IllegalArgumentException: Missing configuration parameter ‘encoding’`
In order to resolve this error, I would suggest to have a look at a similar Community Q&A [here](https://community.denodo.com/answers/question/details?questionId=9060g000000XeO9AAK&title=Sql+Vs+vql+using+denodo+testing+tool)
Hope this helps!!
