All about Selenium Automation: Cucumber DataDriven

In previous post we have seen about cucumber introduction with selenium, now in this post we see how can we write simple feature file with datadriven.

1. Create the feature file to login to AnukoTimesheet (that has some data in the feature file)
2. Create Step definition class file (here we should use Datatable API to read the data)
3. Runner class
4. Run the script

Note : I assume that you have gone through the basic cucumber and installation post earlier.

Step 1 : To create the feature file as LoginTestDataTable .feature under src/test/resources



	Feature: LogIn Action Test With DataTable Demo
	Description: This feature will test a LogIn with DataTable

	Scenario: Successful Login with Valid Credentials
	When User Opens Browser and Navigate to LogIn Page with url
	\|Browser \|url \|
	\|Firefox \|https://timetracker.anuko.com/login.php\|
	And User enters UserName and Password
	\| UserName \| Password \|
	\| guest \| guest \|
	Then Message displayed Login Successfully



	From above feature file we can see that the Browser and the URL are set to parameter and at
	the same time the user name and password too set to "guest" and guest. The whole idea is at runtime we
	need pass these data using DataTable cucumber API.

	Step 2 : Create Step definition class file, before that better run the Runner Class so that we can get the step definition template. Right click and run as Junit Test

	package MavenTest.DemoMavenCucumber;

	import org.junit.runner.RunWith;
	import cucumber.api.CucumberOptions;
	import cucumber.api.junit.Cucumber;
	@RunWith(Cucumber.class)
	@CucumberOptions(
	features = "/yourpath/src/test/resources/LoginTestDataTable.feature",

	plugin = {"pretty", "html:target/cucumber-html-report"},
	tags = {}
	)

	public class RunCukesTest {


	}

	In console should display something like this

	You can implement missing steps with the snippets below:

	@When("^User Opens Browser and Navigate to LogIn Page with url$")
	public void user_Opens_Browser_and_Navigate_to_LogIn_Page_with_url(DataTable arg1) throws Throwable {
	// Write code here that turns the phrase above into concrete actions
	// For automatic transformation, change DataTable to one of
	// List<YourType>, List<List<E>>, List<Map<K,V>> or Map<K,V>.
	// E,K,V must be a scalar (String, Integer, Date, enum etc)
	throw new PendingException();
	}

	@When("^User enters UserName and Password$")
	public void user_enters_UserName_and_Password(DataTable arg1) throws Throwable {
	// Write code here that turns the phrase above into concrete actions
	// For automatic transformation, change DataTable to one of
	// List<YourType>, List<List<E>>, List<Map<K,V>> or Map<K,V>.
	// E,K,V must be a scalar (String, Integer, Date, enum etc)
	throw new PendingException();
	}

	@Then("^Message displayed Login Successfully$")
	public void message_displayed_Login_Successfully() throws Throwable {
	// Write code here that turns the phrase above into concrete actions
	throw new PendingException();

	Step 3 : Now create the proper step definition for feature file as this

	package MavenTest.DemoMavenCucumber;

	import java.util.List;
	import java.util.concurrent.TimeUnit;
	import org.openqa.selenium.By;
	import org.openqa.selenium.WebDriver;
	import org.openqa.selenium.WebElement;
	import org.openqa.selenium.firefox.FirefoxDriver;
	import org.openqa.selenium.support.ui.ExpectedConditions;
	import org.openqa.selenium.support.ui.WebDriverWait;
	import cucumber.api.DataTable;
	import cucumber.api.java.en.Then;
	import cucumber.api.java.en.When;
	public class LoginAjukoTSWithDataTable {
	static WebDriver driver = null;


	@When("^User Opens Browser and Navigate to LogIn Page with url$")
	public void user_Navigate_to_LogIn_Page(DataTable tablelogin) throws Throwable {
	// Write code here that turns the phrase above into concrete actions

	List<List<String>> data1 = tablelogin.raw();
	// to check whether browser set to FireFox or not
	if (data1.get(1).get(0).equals("Firefox")){
	System.out.println("inif condition");
	driver = new FirefoxDriver();
	}

	// open the time tracker url now
	driver.get(data1.get(1).get(1));
	driver.manage().timeouts().implicitlyWait(10, TimeUnit.SECONDS);
	driver.manage().window().maximize();


	}
	@When("^User enters UserName and Password$")
	public void user_enters_UserName_and_Password(DataTable table) throws Throwable {

	// Write code here that turns the phrase above into concrete actions
	// read the data from the datatable API and create a list so that we can access them using index at //later point. // Represents the data from a Gherkin data table, Cucumber will convert the table in Gherkin to //a DataTable instance and pass it to a step definition.
	List<List<String>> data =table.raw(); // to get all the

	System.out.println(data.get(0).get(1));
	System.out.println(data.get(1).get(1));

	WebElement enterusername=driver.findElement(By.id("login"));

	waitforelement(enterusername);
	// if success then enter data to username
	enterusername.sendKeys(data.get(1).get(0));

	WebElement enterpwd=driver.findElement(By.id("password"));

	waitforelement(enterpwd);
	// if success then enter data to username
	enterpwd.sendKeys(data.get(1).get(1));

	// to click on button

	WebElement loginbtn=driver.findElement(By.id("btn_login"));

	waitforelement(loginbtn);
	// if success then enter data to username
	loginbtn.click();



	}
	public static String waitforelement(WebElement element) {
	// TODO Auto-generated method stub
	String msg;
	try {
	WebDriverWait wait = new WebDriverWait(driver, 30);
	// below method will check for visibility of the element i.e in this case its username element
	wait.until(ExpectedConditions.visibilityOf(element));
	msg="PASS";
	System.out.println(msg);
	} catch (Exception e) {
	System.out.println("waitForElementPresent method failed! "+ e.getMessage());
	msg="FAIL -waitForElementPresent method failed! "+ e.getMessage() ;
	}
	return msg;
	}

	@Then("^Message displayed Login Successfully$")
	public void message_displayed_Login_Successfully() throws Throwable {
	// Write code here that turns the phrase above into concrete actions
	System.out.println("Login successful ");

	}

	}
