Summary

While using BDD style reports appending reports to existing reports does not works and fails.

Expected Behavior

User should be able to append to existing reports while using BDD style reports.

Current Behavior

ExtentReport fails to generate when trying to append to existing report

Sample

package testng;

import com.aventstack.extentreports.ExtentReports;
import com.aventstack.extentreports.ExtentTest;
import com.aventstack.extentreports.GherkinKeyword;
import com.aventstack.extentreports.reporter.ExtentHtmlReporter;
import com.aventstack.extentreports.reporter.configuration.ChartLocation;
import org.testng.annotations.Test;

import java.io.File;

public class ExtentTestNGTest {

    @Test
    public void test1() throws ClassNotFoundException {
        ExtentReports extentReports = new ExtentReports();
        File reportFileLocation = new File("ExtentReport.html");
        ExtentHtmlReporter extentHtmlReporter = new ExtentHtmlReporter(reportFileLocation.getName());
        extentHtmlReporter.config().setChartVisibilityOnOpen(true);
        extentHtmlReporter.config().setTestViewChartLocation(ChartLocation.TOP);
        extentHtmlReporter.config().setDocumentTitle("Test Tile");
        extentHtmlReporter.config().setReportName("Test Report");
        extentHtmlReporter.setAppendExisting(true);
        extentReports.attachReporter(extentHtmlReporter);
        ExtentTest feature = extentReports.createTest("Test 1");
        ExtentTest scenario = feature.createNode(new GherkinKeyword("Scenario"), "Test Scenario 1");
        ExtentTest step = scenario.createNode(new GherkinKeyword("Given"), "some step");
        extentReports.flush();
    }

    @Test
    public void test2() throws ClassNotFoundException {
        ExtentReports extentReports = new ExtentReports();
        File reportFileLocation = new File("ExtentReport.html");
        ExtentHtmlReporter extentHtmlReporter = new ExtentHtmlReporter(reportFileLocation.getName());
        extentHtmlReporter.config().setChartVisibilityOnOpen(true);
        extentHtmlReporter.config().setTestViewChartLocation(ChartLocation.TOP);
        extentHtmlReporter.config().setDocumentTitle("Test Tile");
        extentHtmlReporter.config().setReportName("Test Report");
        extentHtmlReporter.setAppendExisting(true);
        extentReports.attachReporter(extentHtmlReporter);
        ExtentTest feature = extentReports.createTest("Test 2");
        ExtentTest scenario = feature.createNode(new GherkinKeyword("Scenario"), "Test Scenario 2");
        ExtentTest step = scenario.createNode(new GherkinKeyword("Given"), "some step");
        extentReports.flush();
    }
}

Failure Log:

SEVERE: Error executing FreeMarker template
FreeMarker template error:
The following has evaluated to null or missing:

----
Tip: It's the step after the last dot that caused this error, not those before it.
----
Tip: If the failing expression is known to be legally refer to something that's sometimes null or missing, either specify a default value like myOptionalVar!myDefault, or use <#if myOptionalVar??>when-present<#else>when-missing</#if>. (These only cover the last step of the expression; to cover the whole expression, use parenthesis: (myOptionalVar.foo)!myDefault, (myOptionalVar.foo)??
