Kotlin is a general-purpose, open-source, statically typed programming language that combines object-oriented and functional programming features. So, it is a strong and powerful language that helps the automation engineers to write their automation scripts and also develop the Extent Report. This article helps the automation engineers to up skill and develop the extent reports using a different language like Kotlin.

Extent Report Generation with Kotlin
 Pre-requisites
Following are the pre-requisites to generate Extent reports with Kotlin:
 Install Java SDK 8 and above.
 Install Eclipse or IntelliJ IDEA IDEs.
 Install the Kotlin plugin in IDEs. Here, we are using Eclipse as IDE and Kotlin plugin for Eclipse
downloaded from https://marketplace.eclipse.org/content/kotlin-plugin-eclipse.
 The latest version of following maven dependencies:
o testng
o selenium-java
o selenium-server
o kotlin-test
o kotlin-stdlib-jdk8
o extentreports
 Step-by-step Procedure
Step 1: Create a maven project and add the above dependencies in pom.xml of the project.
Step 2: Create a Kotlin class to keep the logic to generate the Extent Report. Let say the class name
is AutomationReport. Here, we are using ITestListener interface of TestNG to control the executions and
results. Below is the code snippet of the AutomationReport class to implement the ITestListener and
declare the objects for ExtentSparkReporter, ExtentReports, and ExtentTest,
class AutomationReport : ITestListener {
public lateinit var sparkReporter: ExtentSparkReporter
public lateinit var extentReport: ExtentReports
public lateinit var extentTest: ExtentTest
…}
Step 3: Create an override method onStart() with logic to generate an HTML template for the test report,
override fun onStart(testContext: ITestContext) {
try {
sparkReporter = ExtentSparkReporter(System.getProperty(“user.dir”) + “/AutomationReport/”)
sparkReporter.config().setDocumentTitle(“Kotlin Automation”)
sparkReporter.config().setReportName(“Automation Execution Report”)
sparkReporter.config().setTheme(com.aventstack.extentreports.reporter.configuration.Theme.DARK)
extentReport = ExtentReports()
extentReport.attachReporter(sparkReporter)
extentReport.setSystemInfo(“Application Name”, “Kotlin Report Demo”)

extentReport.setSystemInfo(“Platform”, System.getProperty(“os.name”))
extentReport.setSystemInfo(“Environment”, “QA”)
} catch (e: Exception) {
e.printStackTrace()
}
}
Step 4: Create an override method onTestStart() with logic to collect current test case name and add it to
the report,
override fun onTestStart(result: ITestResult) {
var testName: String = result.getMethod().getMethodName()
extentTest = extentReport.createTest(testName)
}
Step 5: Create an override method onTestSuccess() with logic to add pass status to the report,
override fun onTestSuccess(result: ITestResult) {
var testName: String = result.getMethod().getMethodName()
try {
extentTest.log(
Status.PASS,
MarkupHelper.createLabel(testName + ” Test Case PASSED”, ExtentColor.GREEN)
)
} catch (e: Exception) {
e.printStackTrace()
}
}
Step 6: Create an override method onTestSkipped() with logic to add skip status to the report,
override fun onTestSkipped(result: ITestResult) {
var testName: String = result.getMethod().getMethodName()
try {
extentTest.log(
Status.SKIP,
MarkupHelper.createLabel(testName + ” Test Case SKIPPED”, ExtentColor.ORANGE)
)
} catch (e: Exception) {
e.printStackTrace()
}
}
Step 7: Create an override method onTestFailure() with logic to add fail status to the report,
override fun onTestFailure(result: ITestResult) {
var driver: WebDriver
var currentClass = result.getInstance()
var testName: String = result.getMethod().getMethodName()

try {
driver = (currentClass as AutomationBase).getDriverInstance()
var screenshotPath = Utilities().screenshotCapture(driver, result.getName())
extentTest.log(
Status.FAIL,
MarkupHelper.createLabel(testName + ” Test Case FAILED”, ExtentColor.RED)
)
extentTest.log(
Status.FAIL,
MarkupHelper.createLabel(“Reason for Failure: ” + result.getThrowable().toString(),
ExtentColor.RED)
)
extentTest.addScreenCaptureFromPath(screenshotPath)
} catch (e: Exception) {
e.printStackTrace()
}
}
Step 8: Create an override method onFinish() with logic to store HTML report to the specified path and
flush extent report instance,
override fun onFinish(testContext: ITestContext) {
try {
extentReport.flush()
val dateFormat = SimpleDateFormat(“dd-MMM-yyyy_HH-mm-ss”)
val date = Date()
val filePathdate: String = dateFormat.format(date).toString()
var actualReportPath: String = System.getProperty(“user.dir”) + “/AutomationReport/” +
“index.html”
File(actualReportPath).renameTo(
File(
System.getProperty(“user.dir”) + “/AutomationReport/”
+ “Automation_Report_” + filePathdate + “.html”
)
)
} catch (e: Exception) {
e.printStackTrace()
}
}
Step 9: Create another class called Utilities to keep common utility functions required for automation. Here,
we just added one utility to capture the screenshot. In onTestFailure() method, we already used a method
called screenshotCapture(). Below is the code snippet to capture the screenshot,
fun screenshotCapture(driver: WebDriver, fileName: String): String {
var destination: String = “”
try {
var scrFile = (driver as TakesScreenshot).getScreenshotAs(OutputType.FILE)
var dateFormat = SimpleDateFormat(“yyyyMMddHHmmss”)
var cal = Calendar.getInstance()
var path = File(“Failure_Screenshots”).getAbsolutePath()

destination = path + “/” + fileName + dateFormat.format(cal.getTime()) + “.png”
scrFile.copyTo(File(destination))
} catch (e: Exception) {
e.printStackTrace()
}
return destination
}
Step 10: Prior to starting the automation execution, you have to map the AutomationReport class to your
test runner class (the class which starting your driver instance within TestNG annotation). You can
represent AutomationReport class in test runner class as below,
@Listeners(AutomationReport::class)
Step 11: Now, you can run your test cases using testng.xml and once execution complete the HTML report
will generate inside the AutomationReport folder in the project structure. Following are some excerpts of
the Extent Report:
We hope you got an idea of the Extent Report implementation using Kotlin language. Try to use the above
step-by-step procedure in your automation world and explore it.
