Learning java selenium webdriver

Today, we are going to something different, we explore software test technology. As end user, we are mostly dealing with point and click, and with this article, we are going to learn how to test user interface.

There are many testing software out there, just google and you find plenty. In this article, we are going to use Java Selenium webdriver. To quickly start, you will have to complete these bullet points. For complete information of selenium, read here.

• download latest stable selenium java driver


• setup your IDE to reference this jar.

or additional optional download at http://docs.seleniumhq.org/download/



Let's see continue this article with two example.

import java.util.List;

import org.openqa.selenium.By;
import org.openqa.selenium.WebDriver;
import org.openqa.selenium.WebElement;
import org.openqa.selenium.firefox.FirefoxDriver;

public class GoogleSuggest {

    public static void main(String[] args) throws Exception {
        // The Firefox driver supports javascript
        WebDriver driver = new FirefoxDriver();

        // Go to the Google Suggest home page
        driver.get("http://www.google.com/webhp?complete=1&hl=en");

        // Enter the query string "Cheese"
        WebElement query = driver.findElement(By.name("q"));
        query.sendKeys("Cheese");

        // Sleep until the div we want is visible or 5 seconds is over
        long end = System.currentTimeMillis() + 5000;
        while (System.currentTimeMillis() < end) {
            WebElement resultsDiv = driver.findElement(By.className("gssb_e"));

            // If results have been returned, the results are displayed in a drop down.
            if (resultsDiv.isDisplayed()) {
              break;
            }
        }

        // And now list the suggestions
        List<WebElement> allSuggestions = driver.findElements(By.xpath("//td[@class='gssb_a gbqfsf']"));

        for (WebElement suggestion : allSuggestions) {
            System.out.println("suggestion => " + suggestion.getText());
        }

        driver.quit();
    }

}

import org.junit.Before;
import org.junit.Test;
import org.openqa.selenium.WebDriver;
import org.openqa.selenium.firefox.FirefoxDriver;

import com.thoughtworks.selenium.SeleneseTestBase;
import com.thoughtworks.selenium.webdriven.WebDriverBackedSelenium;

public class BaseSeleniumTest extends SeleneseTestBase {

    @Before
    public void setUp() throws Exception {
            WebDriver driver1 = new FirefoxDriver();
            String baseUrl = "http://google.com/";
            selenium = new WebDriverBackedSelenium(driver1, baseUrl);
    }

    @Test
    public void testGoogle() throws Exception {
    	selenium.open("http://google.com/");
    	System.out.println(selenium.getTitle());
    	assertEquals("Google", selenium.getTitle());
    	selenium.close();
    }
}

The first example construct a FireFox WebDriver. Load google url and mimic a typing by sending a keys of Cheese to the query. When Web Element resultsDiv is displayed, then all the suggestion get printed.

The second example is much easier to construct test. By extending SeleneseTestBase, you can use the object selenium and start to call the rich methods it provides for your sub test class. As seem here, similar to the first example, the test started with construction of FirefoxDriver. Then the very familiar junit test, open up google link, assert that the title is Google and then close the selenium object.
