You need to have the testng jar under classpath   try C  projectfred gt  java -cp  path-tojar testng jar path to yourtest classes  org testng TestNG testng xml   Update   Under linux I ran this command and it would be some thing similar on Windows either  test bin  java -cp       lib    org testng TestNG testng xml   Directory structure    bin - All my test packages are under bin including testng xml  src - All source files are under src  lib - All libraries required for the execution of tests are under this    Once I compile all sources they go under bin directory  So  in the classpath I need to specify contents of bin directory and all the libraries like testng xml  loggers etc over here  Also copy testng xml to bin folder if you dont want to specify the full path where the testng xml is available     bin     -- testng xml     -- testclasses     -- Properties files if any    lib     -- testng jar     -- log4j jar   Update   Go to the folder MyProject and type run the java command like the way shown below -   java -cp     C  Program Files jbdevstudio4 studio plugins    org testng TestNG testng xml   I believe the testng xml file is under C  Users me workspace MyProject if not please give the full path for testng xml file

If you are using Maven  you can run it from the cmd line really easy  cd into the directory with the testng xml  or whatever yours is called  the xml that has all the classes that will run  and run this cmd   mvn clean test -DsuiteXmlFile testng xml    This page explains it in much more detail  How to run testng xml from Maven command line  I didn t know it mattered if you were using Maven or not so I didn t include it in my search terms  I thought I would mention it here in case others are in the same situation as I was

I had faced same problem because I downloaded TestNG plugin from Eclipse  Here what I did to get the Job done        After adding TestNG to your project library create one folder in your Project names as lib   name can be anything       Go to  C  Program Files Eclipse eclipse-java-mars-R-win32-x86 64 eclipse plugins  location and copy com beust jcommander 1 72 0 jar and org testng 6 14 2 r20180216145 jar file to created folder  lib      Note   Files are testng jar and jcommander jar    Now Launch CMD  and navigate to your project directory and then type   Java -cp C  Users User123 TestNG lib  C  Users User123 TestNG bin org testng TestNG testng xml     That s it   Let me know if you have any more concerns

If none of the above answers work  you can run the test in IDE  get the class path and use it in your command  Ex  If you are using Intellij IDEA  you can find it at the top of the console screenshot below      Clicking on the highlighted part expands and displays the complete class path   you need to remove the references to jars inside the folder  JetBrains IntelliJ IDEA Community Edition 2019 1 3   java -cp  path copied  org testng TestNG testng xml

Thanks a lot it was really very helpful   I was able to run my TestNG classes using command line  but still I would like to wrap-up the things one last time as follows    1  Set the classpath for the testng jar in the environment variables  either manually or via command line    2  Create a new folder  MyTest    3  Compile all your classes testNG java  and put them  class files   in a new folder  Mytest bin    4  Put your  testng xml  and   properties  files to  Mytest bin  again   5  Put all the  jar files  testng selenium    etc  in a new folder  Mytest lib    6  Browse to the folder  bin  via command line and run the command java -cp     lib     org testng TestNG testng xml   this should run your testNG cases
