How to run TestNG from command line

How exactly do I run a .java TestNG project from a command line?

I have read through the TestNG documentation, and tried the following to no avail:

C:\projectfred> java org.testng.TestNG testng.xml

... with the following testng.xml file in my project:

<!DOCTYPE suite SYSTEM "http://testng.org/testng-1.0.dtd" >
<suite name="SuiteAll" verbose="1">
<test name="TestAll">
<package name="com.project.fred.tests"/>

The error I get is this:

Exception in thread "main" java.lang.NoClassDefFoundError: org/testng/TestNG
Caused by: java.lang.ClassNotFoundException: org.testng.TestNG
at java.net.URLClassLoader$1.run(Unknown Source)
at java.security.AccessController.doPrivileged(Native Method)
at java.net.URLClassLoader.findClass(Unknown Source)
at java.lang.ClassLoader.loadClass(Unknown Source)
at sun.misc.Launcher$AppClassLoader.loadClass(Unknown Source)
at java.lang.ClassLoader.loadClass(Unknown Source)
Could not find the main class: org.testng.TestNG. Program will exit.

Obviously, I am not referencing TestNG correctly in my command line. Does anyone know how to get this working?

Answer Source

You need to have the testng.jar under classpath.

try C:\projectfred> java -cp "path-tojar/testng.jar:path_to_yourtest_classes" org.testng.TestNG testng.xml


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.

    -- testng.xml
    -- testclasses
    -- Properties files if any.
    -- testng.jar
    -- log4j.jar


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
