Assuming that you set up your classes properly in the XML file, you can try this:

• Download the TestNG library archive http://dl.bintray.com/testng-team/testng-eclipse-release/zipped/ (7.0.0 is the latest I believe).

Extract to a folder called TestNG on the C:\\ directory

Set the classpath environment (TestNG folder and your Project folder)

Change directory (cd) into your project folder and then write these commands:

set classpath=C:\eclipse-2018\Tests\bin;C:\TestNG\plugins\*

java -classpath %classpath% org.testng.TestNG ZaleniumMiniRegression.xml

That's it.

If you've made a runnable jar file with a main method you could simply do:

java -jar <Your runnable jar file>.jar
