Cannot execute testcase exported from selenium ide as java/junit4/remote control in eclipse ide - selenium

Question

I am new to testing and i am trying to learn how to run recorded test cases in selenium ide in eclipse.
I recorded a testcase to search word selenium in the Google.
I exported it as java/junit4/remote control
Then i strated a new project in eclipse and add "java 4.12"and "selenium stand
alone server" external jar files.
I add the exporetd code to the project.
Then i started command prompt and executed selenium stand alone server.
Then i clicked run as junit in eclipse ide.
Firefox launched but an error is occured.
below is the code i executed:
package please;
import com.thoughtworks.selenium.*;
import org.junit.After;
import org.junit.Before;
import org.junit.Test;
import static org.junit.Assert.*;
import java.util.regex.Pattern;
public class please {
private Selenium selenium;
#Before
public void setUp() throws Exception {
selenium = new DefaultSelenium("localhost", 4444, "*chrome", "https://www.google.lk/");
selenium.start();
}
#Test
public void testPlease() throws Exception {
selenium.open("/?gfe_rd=cr&ei=10SKWaOqJ46AuATcuKPAAg");
selenium.type("id=lst-ib", "selenium");
selenium.type("id=lst-ib", "selenium");
assertEquals("selenium - Google Search", selenium.getTitle());
}
#After
public void tearDown() throws Exception {
selenium.stop();
}
}
This is what the result looks like

Answer 1

Recording tests via Selenium IDE is rarely a good option, mainly because many code snippets has to be refactored, lack of abstraction, modularity and so on (list is quite long actually). Looking at your code, I think that the problem is in the driver you are trying to use. According to this selenium mirror at Github. You should migrate to using WebDriver, instead of DefaultSelenium:
#deprecated The RC interface will be removed in Selenium 3.0. Please migrate to using WebDriver.
So, Selenium Interface and DefaultSelenium Class both belong to Selenium 1 and are deprecated. Selenium has advanced to Selenium 3 (WebDriver).
You will want to use the following classes as these are part of Selenium 3 (WebDriver). WebDriver is an interface used by various Selenium 3 drivers.
import org.openqa.selenium.By;
import org.openqa.selenium.WebDriver;
import org.openqa.selenium.WebElement;
Then you have various drivers that you can use. RemoteWebDriver / HtmlUnitDriver / FireFoxDriver / ChromeDriver / IEDriverServer etc. You will want to import the driver in your Java class.
Selenium selenium = new DefaultSelenium();
Becomes
WebDriver driver = new FireFoxDriver();

If your running the test using Selenium-Server try: (replace firefox with your browser version:
DesiredCapabilities capabillities= DesiredCapabilities.firefox();
capabillities.setCapability("platform", Platform.ANY);
capabillities.setCapability("name", "Testing Selenium-2 Remote WebDriver");
WebDriver driver = new RemoteWebDriver( new URL("http://localhost:4444/wd/hub"), capabillities);
driver.get("http://www.google.com");
assertEquals("Google", this.driver.getTitle());
