When i'm trying to run the test suite, am getting this exception. We are using maven project here and i am done with refreshing, cleaning, reinstalling testNG and then imported the maven projects but then also am getting the same exception. Please suggest any ways that am missing here.

Answer 1

I faced the similar issue on importing maven with testng project. This was solved by converting again into TestNg project by

right click on eclipse project > TestNG > Convert to TestNG

and replacing the existing testng.xml file with the newly created. Clean and update the maven project with mvn install

Note: take backup of your testng.xml

Answer 2

For me it was that I added Skip Tests checkbox/flag in the Maven Build of the Project

Therefore the test classes weren't compiled and then weren't found by TestNG

Answer 3

include the package name with class. It will remove your name. I also got the same issue but adding the package name with class fixed this issue.

Answer 4

I also had this issue. I'm using IntelliJ IDEA. I was using src/main/java for configuration files and src/test/java for test files.
Because of this testNG couldn't find the class path. To prevent getting that error need to move all the files from src/main/java to src/test/java or vice versa.

Answer 5

I had no problems with this until recently.

Now I had to move the suite's xml test file into the root of the project I was testing.

It may be that there is a setting to point at the classes I am testing, but I have not found it.

Answer 6

I also ran into the same problem with TestNG version 6.14.2

However, this was due to a foolish mistake on my end and there is no issue whatsoever with maven, testng or eclipse. What I was doing was -

1. Run project as "mvn clean"
2. Select "testng.xml" file and right click on it to run as TestNG suite
3. This was giving me the same error as reported in the original question
4. I soon realized that I have not compiled the project and the required class files have not been generated that the TestNG would utilize subsequently
5. The "target" folder will be generated only after the project is compiled (Run as "mvn build")
6. If your project is compiled, this issue should not be there.
