How to launch browser using selenium with cucumber - cucumber

Question

I am newbie for cucumber framework, I have worked on selenium webdriver using testNG framework. I have to start cucumber framework, I have installed cucumber plugin to eclipse but dont know how to start writting code.
And what is the difference between cucumber and cucumber-jvm, and which is the best?
Could anyone pls help me out?
Thanks in advance.

Answer 1

You can find lots of info on what dependecies you should use for your project on the Cucumber main site Cucumber Documentation
Cucumber base is Ruby
Cucumber-JVM is Java
start with creating a src/test/resources
create a file named anything you want (keep it to the thing you want to test) and end it with .feature
Feature: Calculator should work accourding to standard calculator devices
Scenario: addition
Given a calculator I just turned on
When I add 4 and 5
Then the result is 9
put this in as a guide line and try to run it. it should give you a call missing steps.
create a new java file in src/test/java and call it RunCukesTest this wil later be the starter of all your features.
the output you just got from the feature in the console can be put in a .java call it something to do with the feature like CalculatorSteps.java put this in the same folder as your RunCukesTest.java
import cucumber.api.CucumberOptions;
import cucumber.api.junit.Cucumber;
import org.junit.runner.RunWith;
#RunWith(Cucumber.class)
#CucumberOptions(
monochrome = false,
plugin = {"pretty","json:target/cucumber.json"} ,
features = "src/test/resources/cucumber",
tags = "~#ignore"
)
public class RunCukesTest {
}
this is the basic you need to start using Cucumber (there is a start example on github)
Now the Selenium question
you will have to initiate a WebDriver _driver;
with driver you create a new ChromeDriver or FireFoxDriver etc
some browsers need a installation ChromeDriver firefox is built in (to my best knowledge)
see the code below
ask if there is anything you don't get
import java.util.concurrent.TimeUnit;
import cucumber.api.java.en.*;
import org.eclipse.jetty.util.thread.Timeout;
import org.junit.After;
import org.junit.Before;
import org.junit.Test;
import org.openqa.selenium.By;
import org.openqa.selenium.Keys;
import org.openqa.selenium.WebDriver;
import org.openqa.selenium.WebElement;
import org.openqa.selenium.htmlunit.HtmlUnitDriver;
import org.openqa.selenium.chrome.ChromeDriver;
import org.junit.Test;
import static org.junit.Assert.assertEquals;
public class NavigationSteps {
WebDriver _driver;
#Given("^i am at \"([^\"]*)\"$")
public void i_am_at_home(String arg1) throws Throwable {
System.setProperty("webdriver.chrome.driver", "C:\\chromedriver.exe");
_driver = new ChromeDriver();
_driver.manage().timeouts().implicitlyWait(20, TimeUnit.SECONDS);
_driver.get(arg1);
Thread.sleep(500);
}
#When("^i click on \"([^\"]*)\"$")
public void i_click_on(String arg1) throws Throwable {
_driver.findElement(By.linkText(arg1)).click();
Thread.sleep(500);
}
#Then("^i expect the title to be \"(.*?)\"\"(.*?)\"$")
public void i_expect_the_title_to_be(String arg1, String arg2) throws Throwable {
String result = (arg1 + " | " + arg2);
Thread.sleep(200);
assertEquals("Title should be",result,_driver.getTitle());
tearDown();
}
#Then("^Header should contain \"(.*?)\"$")
public void header_should_contain(String arg1) throws Throwable {
Thread.sleep(200);
assertEquals("Title should be", arg1, _driver.findElement(By.xpath(".//*[#id='main']/div[1]/div/h1")).getText());
tearDown();
}
#After
public void tearDown() throws InterruptedException
{
_driver.quit();
}
}
EDIT - answers to the questions in nicer format
feature file calls the java file (Run via RunCukesTest or feature file)
the methods to test go into je java steps file
Feature calculator has a CalculatorSteps.java file the scenario is in the feature file the methods in the steps
No, the console outputs this as a Regex to identify the corresponding step the test u write in the method below it.
Given a calculator I just turned on
results into
#Given ("^a calculator I just turned on$")
public void iCanCallThisAnythingIWant(){
#do something
}
see answer 2
Given When Then are the logical way to read a Scenario to keep things readable it should be used in that way. If you find yourself with a long Given When or Then u can split the sentence with a "and" in between. but it doesn't matter in what way u write them.
