You must add external jar files to classpath instead of module path. Steps.

1. Right-click on the project and navigate to properties.
2. Go to the Java Build path, it's in the left section
3. Then go to the libraries section. remove all the jar files from modulatpath.
4. to remove all jar files, select the jar file and click on the remove button on the right side.
5. After that select classpath and click on add external jar and import all the jar files including lib folder.
6. Click on apply and close.

You will then be able to run the test script.
