I was able to set up Microsoft SQL Server database in the configuration file and I could run test scripts successfully.
In case of any errors, you could check the following :
1. Check if you have placed the Microsoft SQL Server [**JDBC Driver**](https://community.denodo.com/docs/html/browse/latest/vdp/administration/appendix/supported_jdbc_data_sources/supported_jdbc_data_sources#supported-jdbc-data-sources) jar file into the **<TESTING_TOOL_HOME>/lib/sqlserver-8.4.1** folder.
2. Make sure the specified JDBC URL is correct and the host is reachable.
3. You can also check **testing-tool.log** under **<TESTING_TOOL_HOME>/log** folder for more information.
Additionally, if you still need help and if you are a user with valid support access then you can raise a support case in Denodo Support Site so that our support team can help you.
Hope this helps!
