How to run TestNG from command line

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.

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.

Ok after 2 days of trying to figure out why I couldn't run the example from

http://www.tutorialspoint.com/testng/testng_environment.htm the following code did not work for me

C:\TestNG_WORKSPACE>java -cp "C:\TestNG_WORKSPACE" org.testng.TestNG testng.xml 

The fix for it is as follows: I came to the following conclusion: First off install eclipse, and download the TestNG plugin. After that follow the instructions from the tutorial to create and compile the test class from cmd using javac, and add the testng.xml. To run the testng.xml on windows 10 cmd run the following line:

java -cp C:\Users\Lenovo\Desktop\eclipse\plugins\org.testng.eclipse_6.9.12.201607091356\lib\*;C:\Test org.testng.TestNG testng.xml 

to clarify: C:\Users\Lenovo\Desktop\eclipse\plugins\org.testng.eclipse_6.9.12.201607091356\lib\* The path above represents the location of jcommander.jar and testng.jar that you downloaded by installing the TESTNG plugin for eclipse. The path may vary so to be sure just open the installation location of eclipse, go to plugins and search for jcommander.jar. Then copy that location and after that add * to select all the necessary .jars.

C:\Test 

The path above represents the location of the testing.xml in your project. After getting all the necessary paths, append them by using ";".

I hope I have been helpful to some of you guys :)

Using " ; " as delimiter on windows issue got resolved.

java -cp "path of class files; testng jar file path" org.testng.TestNG testng.xml 

ex:-

java -cp ".\bin;..\common_lib\*;" org.testng.TestNG testng.xml 

Prepare MANIFEST.MF file with the following content

Manifest-Version: 1.0 Main-Class: org.testng.TestNG 

Pack all test and dependency classes in the same jar, say tests.jar

jar cmf MANIFEST.MF tests.jar -C folder-with-classes/ . 

Notice trailing ".", replace folder-with-classes/ with proper folder name or path.

Create testng.xml with content like below

<?xml version="1.0" encoding="UTF-8"?> <!DOCTYPE suite SYSTEM "http://testng.org/testng-1.0.dtd" > <suite name="Tests" verbose="5"> <test name="Test1"> <classes> <class name="com.example.yourcompany.qa.Test1"/> </classes> </test> </suite> 

Replace com.example.yourcompany.qa.Test1 with path to your Test class.

Run your tests

java -jar tests.jar testng.xml 

Below command works for me. Provided that all required jars including testng jar kept inside lib.

java -cp "lib/*" org.testng.TestNG testng.xml 

I had faced same problem because I downloaded TestNG plugin from Eclipse. Here what I did to get the Job done :

1. After adding TestNG to your project library create one folder in your Project names as lib ( name can be anything ) :

2. 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

3. 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.

You will need to use semicolon as delimiter while specifying the jar and class file path in windows. This solved the issue.
Assuming the class file is under C:.

java -cp ".;C:\testng.jar" org.testng.TestNG testing.xml 

After gone throug the various post, this worked fine for me doing on IntelliJ Idea:

java -cp "./lib/*;Path to your test.class" org.testng.TestNG testng.xml 

Here is my directory structure:

/lib -- all jar including testng.jar /out --/production/Example1/test.class /src -- test.java testing.xml 

So execute by this command:

java -cp "./lib/*;C:\Users\xyz\IdeaProjects\Example1\out\production\Example1" org.testng.TestNG testng.xml 

My project directory Example1 is in the path:

C:\Users\xyz\IdeaProjects\ 

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

I tried everything on this post but it turns out I was missing a jar file. Here's my solution:

Add guice-4.2.2.jar to your jar files if you are getting the following error. If you are using maven then add the following dependency.

<dependency> <groupId>com.google.inject</groupId> <artifactId>guice</artifactId> <version>4.1.0</version> </dependency> Exception in thread "main" java.lang.NoClassDefFoundError: com/google/inject/Stage at org.testng.internal.Configuration.<init>(Configuration.java:33) at org.testng.TestNG.init(TestNG.java:216) at org.testng.TestNG.<init>(TestNG.java:200) at org.testng.TestNG.privateMain(TestNG.java:1312) at org.testng.TestNG.main(TestNG.java:1304) Caused by: java.lang.ClassNotFoundException: com.google.inject.Stage at java.base/jdk.internal.loader.BuiltinClassLoader.loadClass(BuiltinClassLoader.java:602) at java.base/jdk.internal.loader.ClassLoaders$AppClassLoader.loadClass(ClassLoaders.java:178) at java.base/java.lang.ClassLoader.loadClass(ClassLoader.java:522) ... 5 more 

Try below command

java -cp bin\;jars\* org.testng.TestNG testng.xml 

where bin has the compiled classes of your projects and jars folder contains the necessary jars to execute your testng.xml file

Make sure not to use bin\* instead of bin\ as it will lead you to errors. 

Now necessary jars will be your TestNG jar, jcommander jar, and the bsh jar, you can download these jars from here

Your project structure would be something like below -

Project |_ _ bin | _ _ your compiled classes |_ _ jars |_ _ testng.jar |_ _ jcommander.jar |_ _ bsh.jar |_ _ testng.xml 

I have also written an article which explains how to run a testng.xml file while making a new project or in an existing project. Hope you find your solution in the article.

Add this plugin if your project pom.xml

 <plugin> <groupId>org.apache.maven.plugins</groupId> <artifactId>maven-surefire-plugin</artifactId> <version>2.19.1</version> <configuration> <reportsDirectory>./test-output</reportsDirectory> <suiteXmlFiles> <!-- pass testng.xml files as argument from command line --> <suiteXmlFile>${suiteXmlFile}</suiteXmlFile> </suiteXmlFiles> </configuration> </plugin> 

after that use following command to pass the testng xml location:

mvn clean test -Dsurefire.suiteXmlFiles=/path/to/testng.xml 

testng.xml should include details about test classes or packages to run. Here is an example of content in testng.xml file:
