Maven: mvn test gives error + Cannot find class in classpath

Question

Running testng.xml directly from eclipse IDE, test suite gets executed but on executing testng.xml from maven gives error.

Running mvn compile, it says BUILD SUCCESS. But on running mvn testit gives error.

On running maven script through mvn test I am receiving below error:

[INFO]

<suite name="XXXX" parallel="none" >

        <listener class-name="atu.testng.reports.listeners.ATUReportsListener"></listener>
        <listener class-name="atu.testng.reports.listeners.ConfigurationListener"></listener>
        <listener class-name="atu.testng.reports.listeners.MethodListener"></listener>
    </listeners>
  <test name="test1" >
    <classes>
      <class name="com.XXX.tests.XXXX.classtoexecute"/>
    </classes>
 </test> 
</suite>

The project structure is as below:

Answer 1

i had same error,

Move your src folder to Main > Java

it should be "src > Main > Java" >

com.something.test.something

com.something.test.sometest2

now compile/run in maven

Answer 2

Converting non-maven to maven worked for my test project.

right click on project->Configure->Convert it to Maven

Answer 3

I created a same project structure as you described. Copied pom.xml as it is. Below are some steps I took to make it execute the required class.

1. I put testng.xml directly in project's root folder i.e. on same level of pom.xml.

2. Next in testng.xml I wrote

   <classes>
         <class name="com.Local.Tests.TestClass"/>
   </classes>
   

   Check the package name in Java file at the beginning.

3. Run as mvn test.

I could see my selenium tests executing successfully.

    [INFO] Surefire report directory: D:\workspace\TestngPOM\target\surefire-reports
Running TestSuite
Tests run: 2, Failures: 0, Errors: 0, Skipped: 0, Time elapsed: 18.659 sec 

Give it a try.

This is how my maven project structure.
