Create a TestNG runner class for each running thread using Cucumber

I'm writing a framework that uses TestNG and Appium in order to conduct mobile app tests in parallel. Right now i'm trying to implement Cucumber into the framework, which requires a TestNG runner class in order to run the Cucumber tests (see below).



package org.cucumber.tests;

@CucumberOptions(
features="src/test/resources/features",
glue={"org.cucumber.stepdefs"},
plugin = {
"com.cucumber.listener.ExtentCucumberFormatter:" }, monochrome = true)

public class TestNGRunner extends BaseTest {

private static TestNGCucumberRunner testRunner;

@BeforeClass
public void setUP() {
testRunner = new TestNGCucumberRunner(TestNGRunner.class);
ExtentProperties extentProperties = ExtentProperties.INSTANCE;
extentProperties.setReportPath("output/" + this.hashCode() + "-report.html");
}

@Test(description="Tests",dataProvider="features")
public void setUpClass(CucumberFeatureWrapper cFeature) {
testRunner.runCucumber(cFeature.getCucumberFeature());
}

@DataProvider(name="features")
public Object getFeatures() {
return testRunner.provideFeatures();
}

@AfterClass
public static void teardown() {
testRunner.finish();
}

}


I have my tests running in parallel on each connected mobile device using ThreadLocal AppiumDriver (WebDriver) instances and specifying parameters in my testNG.xml file within <test> tags and setting the parallelism to 'tests', example:-



<suite name="Parallel Testing" verbose="1" parallel="tests">

<test name="Samsung Galaxy S7">
<parameter name="platform" value="Android 6.0.1" />
<parameter name="udid" value="#############" />
<parameter name="browserName" value="Chrome" />
<parameter name="chromeDriverPort" value="9515" />
<parameter name="systemPort" value="8201" />
<parameter name="deviceName" value="Samsung Galaxy S7" />

<packages>
<package name="org.cucumber.tests"/>
</packages>
</test>

<test name="Nexus 6P">
<parameter name="platform" value="Android 7.1.1" />
<parameter name="udid" value="########" />
<parameter name="browserName" value="Chrome" />
<parameter name="chromeDriverPort" value="9516" />
<parameter name="systemPort" value="8202" />
<parameter name="deviceName" value="Nexus 6P" />
<packages>
<package name="org.cucumber.tests"/>
</packages>


When it comes to generating a report using ExtentReports, all the tests from every running thread are placed into the same report - see below example.



Extent Report



My understanding of this is that the ExtentProperties.INSTANCE is shared between each of the running threads, so the file path is always overridden.



What i would like is an indiviual report for each running thread, which results in a report for each connected mobile device.



Presumably what i need to do is create a separate instance of the TestNGRunner class for each running thread. My question is - is this actually possible and if so, do i need to change my approach?

    If you are using Vimal's ExtentCucumberFormatter - then the INSTANCE variable is a singleton which will be the same for all threads.. You would probably need to fork the project and create a custom implementation that gives you an individual report per device. However, as devices increase, it will be difficult to read through all reports. I suggest marking tests with tags instead.
