TestNG could not recognise the name of DataSupplier annotated method while running test from testng.xml using IAnnotationTransformer listener.

I am using TestNGIAnnotationTransformerListener that implements IAnnotationTransformer interface of testng to set the enable, invocationCount, priority parameters by reading data from excel. This listener is called in testng.xml.
When test method annotated with @Test(dataProvider="testDataReader") is called from the testng.xml, then exception "org.testng.TestNGException: Method public void RunTest.testRun(org.example.datapojo.Sampledata) requires a @DataProvider named : testDataReader" is returned.

Please refer Other Information section for more details.

[ ] bug report

Environment

Test Data Supplier	1.9.7
TestNG	7.4.0
Build tool	maven
IDE	IntelliJ@2022.1

Is the issue reproducible on a runner?

[ ] IntelliJ

What is the expected behavior?

. TestNG should be able recognise the name of DataSupplier annotated method while running test from testng.xml using IAnnotationTransformer listener.

What is the actual behavior?

. "org.testng.TestNGException: Method public void RunTest.testRun(org.example.datapojo.Sampledata) requires a @DataProvider named : testDataReader"

@himanshusoni30 hi, you may want to check the README's part about IAnnotationTransformer first.

@sskorol thanks for your prompt reply. I have tried below implementation as mentioned in IAnnotationTransformer

org.example.listeners.TestNGIAnnotationTransformerListener

public class TestNGIAnnotationTransformerListener implements IAnnotationTransformerInterceptor {
    @Override
    public void transform(ITestAnnotation annotation, Class testClass, Constructor testConstructor, Method testMethod) {
        List<TestRunManager> list = Reader.of(Sampledata.class).
                from(new File("SampleData.xlsx").
                sheet("sheet0").list();

        list.stream().filter(l -> l.getTestCase().equalsIgnoreCase(testMethod.getName())).forEach(
                l -> {
                    if(l.getExecute().equals(Boolean.TRUE)){
                        annotation.setEnabled(true);
                        annotation.setInvocationCount(l.getInvocationCount());
                        annotation.setPriority(l.getPriority());
                    }else{
                        annotation.setEnabled(false);
                    }
                }
        );
    }
}

created a file io.github.sskorol.core.IAnnotationTransformerInterceptor inside src/main/resources/META-INF/services path
added fully qualified class name org.example.listeners.TestNGIAnnotationTransformerListener (implementation class of IAnnotationTransformerInterceptor interface) in the above file
ran test from testng.xml

Are you using Java9+ modules? Can you share your build config and module.info then.

@himanshusoni30 I checked your code. Your transformer is syntactically broken. You have the wrong number of parentheses. This code shouldn't even compile.

The other issue I see is types' misusage.

List<TestRunManager> list = Reader.of(Sampledata.class)

Here you read into Sampledata.class but expect TestRunManager as an output. It'd theoretically work only if TestRunManager is an interface implemented by Sampledata.class (or a parent class). But I don't see any real benefits of doing this yet.

The other question is in the way you read data from within a transformer. A library already provides a wrapper that does some internal tweaks for reading excel files. And you actually use this style in @DataSupplier body. So I'd refactor the transformer the following way to be consistent:

public class TestNGIAnnotationTransformerListener implements IAnnotationTransformerInterceptor {
    @Override
    public void transform(
        final ITestAnnotation annotation,
        final Class testClass,
        final Constructor testConstructor,
        final Method testMethod
    ) {
        use(XlsxReader.class)
            .withTarget(SampleData.class)
            .read()
            .filter(test -> testMethod.getName().equalsIgnoreCase(test.getTestCaseName()))
            .forEach(test -> {
                    annotation.setEnabled(test.shouldExecute());
                    annotation.setInvocationCount(test.getInvocationCount());
                    annotation.setPriority(test.getPriority());
            });
    }
}

Assuming your SampleData.class looks like the following:

@Data
@Source(path = "data/sample.xlsx")
@Sheet(name = "Sheet1")
public class SampleData {

    @Column(name = "TC", index = 0)
    private String testCaseName;

    @Column(name = "Execute", index = 1, converterClass = BooleanConverter.class)
    private boolean execute;

    @Column(name = "InvocationCount", index = 2, converterClass = IntegerConverter.class)
    private int invocationCount;

    @Column(name = "Priority", index = 3, converterClass = IntegerConverter.class)
    private int priority;

    public boolean shouldExecute() {
        return execute;
    }
}

Note that in the above code Lombok library is used to simplify POJOs handling.

Also, make sure you removed the listener's reference from testng.xml, as you already defined SPI for your transformer class.

And a final note: when you read from the excel file, chances are there will be empty rows that may produce potential NPE. See #109 for details. So I'd reverse the order when you compare method names.

Well, technically, the tests' skipping issue is already addressed in TestNG 7.6.0. They introduced a new data provider flag propagateFailureAsTestFailure that marks the test as failed in case of an exception thrown from the data provider. But this feature will be available only in the next release of test-data-supplier.

By the way, I noticed another issue. Your pom.xml doesn't have aspectj agent configured:

<properties>
    <aspectj.version>1.9.9.1</aspectj.version>
</properties>

<dependency>
    <groupId>org.aspectj</groupId>

            </argLine>
       </configuration>

hi @sskorol , i have made the suggested changes. Previous error is fixed but getting "java.lang.reflect.InvocationTargetException" now.

I see several issues here:

duplicate maven-surefire-plugin block
missing lombok dependency (as it seems like you use its annotations)
empty listeners block in testng xml
not the latest data-supplier version

And finally, the exception says:

Caused by: java.lang.IllegalAccessException: module java.base does not open java.lang to unnamed module @3b07a0d6

So it means you need to add the following to your maven-surefire-plugin argLine:

--add-opens java.base/java.lang=ALL-UNNAMED

It's hard to say which unnamed module requires this. But it should fix your issue.

@sskorol i am very grateful to you for helping me out with the above issues. I have made the changes as per your suggestions and achieved to use data-supplier library successfully in my project. Appreciate you for your valuable time, feedback, and patience :)
