`test-output\testng.css` is a relative path. It is searched into your current working directory, which is where you launched the `java` command from. If the `test-output\testng.css` file isn't there you'll get that error. — Aaron, Jan 20 '20 at 09:52
@Aaron test-output\ is the folder created by testNG itself, i am not sure why it is looking at that locaton. — deepakguna, Jan 20 '20 at 10:13
Did you specify that path anywhere or is it a default of testNG? If you specified it yourself somewhere I'd check if it works better when rewritten as `test-ouput/testng.css`. Otherwise I'd also check that the user launching the `java` command can actually write into this directory — Aaron, Jan 20 '20 at 10:25
@Aaron , No i didn't specify the path for output. It has no restrictions to write in to the current directory. — deepakguna, Jan 20 '20 at 11:22
Someone reported having a [similar issue](https://stackoverflow.com/questions/10075209/testng-ant-task-fails-on-mac-os-x-with-error-no-test-suite-found?noredirect=1) when having an older version of testNG erroneously imported as a dependency, maybe that could be your problem? — Aaron, Jan 20 '20 at 11:41
@Aaron Thank you , i will debug further and post any success here. My Testng version is 7.0.0 — deepakguna, Jan 20 '20 at 12:50

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

If you run into trouble getting the webdriver to run from the command line, check my answer here: https://stackoverflow.com/a/60172758/1843452
