I had to make a jar file from my test classes and add it to my class path. Previously I added my test class file to class path and then I got above error. So I created a jar and added to classpath.

e.g

java -cp "my_jars/*" org.testng.TestNG testing.xml

Was facing a similar issue using IntelliJ and in case it may be helpful to someone else what fixed it for me was to change the Use classpath of module field  to have it as the one that shows the package name

i was facing same issue solution is   you need to check testng file your class created under package in this case class is not found through Test NG  perform below steps just convert your project in to Test NG and over write rplace with new testNG file    Again run this TestNG in this case it is working my case

I just had this problem and I m pretty confident that it s a bug in the TestNG Plugin for eclipse  since I was able to run my tests from the command line just fine    The fix that seems to be working for me and others is just to clean your project  Project   Clean   One person had to re-install the whole plugin

If you have your project open in Eclipse Mars  IDE  Right click on the project in eclipse Click on TestNG Click on  Convert to TestNG   This creates a new testng xml file and prompts you to overwrite the existing one     Warning  this will erase your previous testng xml      Click Yes   Run as Maven test build

When I converted my project with default pacage and a class named addition  to testng xml  It got converted as    lt classes gt         lt class name   addition   gt   lt  classes gt    and was throwing error that class cannot be loaded  If I remove   before addition  the code works fine  So be careful with default package

I got the same Problem while using maven  The solution that worked is  the name of the class in testNG file was different then the actual class Name  Since i changed the classname and testng file was not updated   So make sure className in testNG file should match with the actual className  RestAssuredTest was mistaken written as RestAssuredest in testNG  One of the reason for this problem    lt  xml version  1 0  encoding  UTF-8   gt     lt suite name  Suite  gt      lt test name  Test  gt   lt classes gt     lt class name  com mycompany app AppTest   gt     lt class name  com mycompany app RestAssuredTest   gt    lt class name  com mycompany app appiumTests   gt   lt  classes gt   lt  test gt   lt  -- Test -- gt   lt  suite gt   lt  -- Suite -- gt

I ran into the same issue  Whenever I ran my test  it kept saying classes not found in the classpath  I tried to fix the testng xml file  clean up the project and pretty much everything the answers say here  but none worked  Finally I checked my referenced libraries in build path and there were 34 invalid libraries  turns out I had renamed one of the folders from the path that I had taken the jar files from  I fixed the path and the test ran successfully   So it might be fruitful to check if there are any errors in the referenced jar files before trying the other methods to fix this issue

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 VERSION   java -cp  path copied  org testng TestNG testng xml  If the project is a Maven project  you can add maven surefire plugin and provide testng suite XML file path  navigate to the project directory and run the command  mvn clean install test               lt plugin gt                   lt groupId gt org apache maven plugins lt  groupId gt                   lt artifactId gt maven-surefire-plugin lt  artifactId gt                   lt version gt 2 12 lt  version gt                   lt configuration gt                       lt suiteXmlFiles gt                           lt suiteXmlFile gt config testrun config xml lt  suiteXmlFile gt                       lt  suiteXmlFiles gt                   lt  configuration gt               lt  plugin gt

In my case  the package structure was not proper  it was like folders and sub-folders  I deleted that project and imported again with changing the respective jre  After that it worked for me  e g  Folder structure- TestProject                              -TestSuite1      Package Structure- TestProject TestSuite1

Just do Eclipse  Project   Clean and then run the test cases again  It should work   What it does in background is  that it will call mvn eclipse clean in your project directory which will delete your  project and  classpath files and you can also do a mvn eclipse eclipse - this regenerates your  project and  classpath files  Thus adding the desired class in the classpath
