- Stupidly easy to use
- Works on Mac, Linux and Windows

Before usage - you need to install JDK version 11. I've used the Amazon Corretto 11
Database connection tester is available for OSX (macOS), Linux and Windows.
Download the latest jar from the Releases page. It's the easiest way to get started with Database connection tester.
$ git clone [email protected]:tomaszkyc/database-connection-tester.git
