Getting Null pointer exception

[jagadishchandran]

Getting the following error -

java.lang.NullPointerException

This is the runner class file look like -

@CucumberOptions(
                    monochrome = true,
                    features = "src/test/resources/features/Login.feature",
                    format = { "pretty","html: cucumber-html-reports",
                    "json: cucumber-html-reports/cucumber.json" },
                    plugin = {"com.cucumber.listener.ExtentCucumberFormatter:output/report.html"}

This is the @BeforeClass

---

    @BeforeClass
    public static void setup() throws Throwable {

        // Initiates the extent report and generates the output in the output/Run_<unique timestamp>/report.html file by default.
        ExtentCucumberFormatter.initiateExtentCucumberFormatter();

        // Loads the extent config xml to customize on the report.
        ExtentCucumberFormatter.loadConfig(new File("src/test/resources/extent-config.xml"));

        // User can add the system information as follows
        String [] bInfo = new DriverFactory().browserInfo();

        ExtentCucumberFormatter.addSystemInfo("Browser Name", bInfo[0]);
        ExtentCucumberFormatter.addSystemInfo("Browser version", bInfo[1]);
        ExtentCucumberFormatter.addSystemInfo("Selenium version", "v2.53.0");

        Map<String, String> systemInfo = new HashMap<String, String>();
        systemInfo.put("Cucumber version", "v1.2.5");
        systemInfo.put("Extent Cucumber Reporter version", "2.41.1");
        ExtentCucumberFormatter.addSystemInfo(systemInfo);
    }

Just a wild guess, what happens when you remove the format add-on in your @CucumberOptions?

[dirtmark333]

Hi All! I am also having this issue even without the format add-on in my @CucumberOptions. (My @BeforeClass is more or less the same.)

[jagadishchandran]

Hi Vimal, Is there any precondition like the setup method (for initializing the extent report) in @BeforeClass should be present only in Runner class. The krisp of this issue is like, if the @BeforeClass is present in Runner class, everything works fine. But if you keep in Feature step class, It is throwing this NullPointerException. Please help us to resolve.

[email2vimalraj]

@jagadishchandran : Apologies for the delayed reply. Could you please post some sample with the feature step class for me to reproduce. I'm also thinking of enhancing by removing the dependency of @BeforeClass. You will hear from me soon about the new feature.

Hi all, I have also got Null pointer exception but the Null point at com.cucumber.listener.ExtentCucumberFormatter.feature

I notice that feature() method always getting NULL at line "this.featureTest = extent.startTest("Feature: " + feature.getName());".

public void feature(Feature feature) {
        this.featureTest = extent.startTest("Feature: " + feature.getName());
        Iterator var2 = feature.getTags().iterator();

        while(var2.hasNext()) {
            Tag tag = (Tag)var2.next();
            this.featureTest.assignCategory(new String[]{tag.getName()});
        }
    }

My runner file as below:

@RunWith(Cucumber.class)
@CucumberOptions(plugin = {"com.cucumber.listener.ExtentCucumberFormatter"},features = {"src/test/java/BDD/FirstFeature.feature"}, glue={"steps"})
public class BDDRunner {

    @BeforeClass
    public static void initial()
    {
        ExtentCucumberFormatter.initiateExtentCucumberFormatter();
        ExtentCucumberFormatter.loadConfig(new File("src/extent-config.xml"));
    }
}

Dependency which I am using

         <dependency>
            <groupId>com.vimalselvam</groupId>
            <artifactId>cucumber-extentsreport</artifactId>
            <version>1.1.1</version>
        </dependency>

Please help me for the investigating Thanks for your great support.

[email2vimalraj]

Kindly try the latest version and see how it goes. Re-open in case you find any issues.

[NgocAnHa]

Hi @email2vimalraj, I notice that the latest version is 1.1.1. This version I am using and get the error that I mentioned. If you have time, pls help me to investigate. Many thanks 👍

[email2vimalraj]

The latest released version is 2.0.0. Kindly update in your pom and follow the instructions as mentioned in readme.

[NgocAnHa]

Hi @email2vimalraj The issue has been resolved after using "cucumber-extentsreport version 2.0.0". Thank you for your great support. 👍

Can Someone Help with how to use stubs with cucumber test.
