Can we set dataProvider and dataProviderClass in XML testng or Suite level outside.

[nikhi...@agrostar.in]

Hello,

In below example, dataProvider and dataProviderClass are same for every @Test method.

I have multiple class were dataProvider and dataProviderClass are same. Can we set dataProvider and dataProviderClass in XML testng or Suite level outside?

@Test(priority = 1, dataProvider = "getData", dataProviderClass = DataUtil.class)
public void Test1(LinkedHashMap<String, String> data) {

}

@Test(priority = 2, dataProvider = "getData", dataProviderClass = DataUtil.class)
public void Test2(LinkedHashMap<String, String> data) {

}

@Test(priority =3, dataProvider = "getData", dataProviderClass = DataUtil.class)
public void Test3(LinkedHashMap<String, String> data) {

}

Why not set them via a listener implementation of org.testng.IAnnotationTransformer2 and then plug in this listener using <listeners> tag or an SPI (Service Loader implementation)

Can you please give me an example.

Thanks in advance.

public static class DataProviderAdder implements IAnnotationTransformer {

 

    @Override

    public void transform(ITestAnnotation annotation, Class testClass, Constructor testConstructor, Method testMethod) {

        if (annotation != null) {

            annotation.setDataProvider("someDataProvider");

            annotation.setDataProviderClass(SampleClass.class);

        }

    }

}

 

This should get you started.

 

Thanks & Regards

Thank you Krishnan.

Above code work for me in 6.8 version of testng but fails in 6.11 version.

Below code used for generating XML FIle:

static List<Class> listenerClasses = new ArrayList<Class>();

public static List<XmlSuite> genarateXmlFile() {
    XmlSuite suite = new XmlSuite();
    suite.setName(Constant.BaseTestHelperConstant.SUITENAME);

    XmlTest test = new XmlTest(suite);

    test.setName(Constant.BaseTestHelperConstant.TESTCASENAME);

    test.setGroupByInstances(true);

    List<XmlClass> classes = new ArrayList<XmlClass>();
    for (int i = 0; i < Common.BaseTestHelperClass.sheetsName.size(); i++)
        classes.add(new XmlClass(Constant.BaseTestHelperConstant.TESTSUITEPATH + Common.BaseTestHelperClass.sheetsName.get(i)));

    listenerClasses.add(main.java.com.agrostar.utility.DataProviderAdder.class);

    test.setXmlClasses(classes);

    List<XmlSuite> suites = new ArrayList<XmlSuite>();
    suites.add(suite);

    System.out.println("Printing TestNG Suite Xml");
    System.out.println(suite.toXml());

    return suites;

}

public static void runXmlSuite(List<XmlSuite> suites) {
    TestNG tng = new TestNG();
    tng.setXmlSuites(suites);
    tng.setListenerClasses(listenerClasses);
    tng.run();
}

Exception in 6.11 testng:  incompatible types: java.util.List<java.lang.Class> cannot be converted to java.util.List<java.lang.Class<? extends org.testng.ITestNGListener>>

Please let me know if you have any workaround.

Thanks for your help.

Either use tng.addListener() or
Change listenerClasses definition to :

List<Class<? extends ITestNGListener>> = new Array list<>()

Solution:

set dataProvider and dataProviderClass in XML testng or Suite level outside.

package main.java.com.agrostar.utility;



import org.testng.IAnnotationTransformer;
import org.testng.annotations.ITestAnnotation;


import java.lang.reflect.Constructor;
import java.lang.reflect.Method;

public class DataProviderAdder implements IAnnotationTransformer {

    @Override
    public void transform(ITestAnnotation annotation, Class testClass, Constructor testConstructor, Method testMethod) {

        if (annotation != null) {

            annotation.setDataProvider("getData");

            annotation.setDataProviderClass(DataUtil.class);

        }

    }
}

Generate XML using below code:

public static List<XmlSuite> genarateXmlFile() {

    List<XmlTest> tests = new ArrayList<XmlTest>();

    List<XmlSuite> suites = new ArrayList<XmlSuite>();

    XmlSuite suite = new XmlSuite();
    suite.setName(Constant.BaseTestHelperConstant.SUITENAME);

    suite.setPreserveOrder(true);

    for (int i = 0; i < Common.BaseTestHelperClass.sheetsName.size(); i++) {

        XmlTest test = new XmlTest(suite);

        List<XmlClass> classes = new ArrayList<XmlClass>();

        test.setName(Common.BaseTestHelperClass.sheetsName.get(i));
        classes.add(new XmlClass(Constant.BaseTestHelperConstant.TESTSUITEPATH + Common.BaseTestHelperClass.sheetsName.get(i)));
        test.setXmlClasses(classes);
        tests.add(test);
    }

    listenerClasses.add(main.java.com.agrostar.utility.DataProviderAdder.class);

    suites.add(suite);

    System.out.println("Printing TestNG Suite Xml");
    System.out.println(suite.toXml());

    System.out.println("suites---------" + suites);

    return suites;

}
