using @parameter annotation in testng test case throwing exception

Question

@BeforeClass
@Parameters("folderName")
public void setUp(String folderName) {
    createLogger(this.getClass().getSimpleName(),folderName);
    configureDriver();
}

@AfterClass
public void tearDown() {
    shutDown();
}

When I run the above test case using maven

 mvn path/to/pom.xml clean -Dtest=HerveLeger test

It's giving following exception

setUp(com.hb.MFA.HerveLeger)  Time elapsed: 0.359 sec  <<< FAILURE!
org.testng.TestNGException: 
Parameter 'folderName' is required by @Configuration on method setUp_HerveLeger but has not been marked @Optional or defined

Here it is my TestNG.xml file

<test name="TEST NAME"> 
    <parameter name="folderName" value="TEstName"></parameter> 
    <classes> 
        <class name="com.org.Test" />
    </classes>
</test>

Please help me any one to solve this issue

Answer 1

Parameter 'folderName' is required by @Configuration on method setUp_HerveLeger but has not been marked @Optional or defined

It says it right in the exception description. You need to define a parameter in you're TestNG XML file or provide an optional value.

@Parameters("folderName")
public void setUp(@Optional("Insert folder name here or leave empty") String folderName) {

It is explained clearly in the TestNG Documentation: TestNG Parameters

Example TestNG.xml

<suite name="testSuiteNameHere">
<parameter name="folderName" value="SomeValue"/>
</suite>

Answer 2

try this

mvn path/to/pom.xml clean -Dtest={testname} -DfolderName=HerveLeger test

Also you can try, removing @parameters and add simple java call

System.getProperty("folderName");

and pass it with

-DfolderName="HerveLeger"
