Ottenere l'esempio Selenium-WebDriver per funzionare

Sono completamente nuovo al Selenio e voglio solo installare ed eseguire l'esempio per cominciare, come descritto qui: http://www.seleniumhq.org/docs/03_webdriver.jsp Ho installato Java SE 9.0.1 JDK, Eclipse IDE per sviluppatori Java e Apache Maven. Quindi ho creato un pom.file xml: 

<?xml version="1.0" encoding="UTF-8"?>
<project xmlns="http://maven.apache.org/POM/4.0.0"
                 xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
                 xsi:schemaLocation="http://maven.apache.org/POM/4.0.0 http://maven.apache.org/xsd/maven-4.0.0.xsd">
        <modelVersion>4.0.0</modelVersion>
        <groupId>MySel20Proj</groupId>
        <artifactId>MySel20Proj</artifactId>
        <version>1.0</version>
        <dependencies>
            <dependency>
                <groupId>org.seleniumhq.selenium</groupId>
                <artifactId>selenium-server</artifactId>
                <version>3.0.1</version>
            </dependency>
        </dependencies>
</project>

Poi ho fatto mvn clean install

Poi ho importato il progetto Maven in Eclipse.

Ho anche installato il plugin m2eclipse.

Ho chiamato il progetto MySel20Proj.

Qui, ho creato una classe: Selenium2Example.java

Qui, ho incollato il codice dal manuale: 

package org.openqa.selenium.example;

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.ExpectedCondition;
import org.openqa.selenium.support.ui.WebDriverWait;

public class Selenium2Example {
     public static void main(String[] args) {
        // Create a new instance of the Firefox driver
        // Notice that the remainder of the code relies on the interface, 
        // not the implementation.
        WebDriver driver = new FirefoxDriver();

        // And now use this to visit Google
        driver.get("http://www.google.com");
        // Alternatively the same thing can be done like this
        // driver.navigate().to("http://www.google.com");

        // Find the text input element by its name
        WebElement element = driver.findElement(By.name("q"));

        // Enter something to search for
        element.sendKeys("Cheese!");

        // Now submit the form. WebDriver will find the form for us from the element
        element.submit();

        // Check the title of the page
        System.out.println("Page title is: " + driver.getTitle());

        // Google's search is rendered dynamically with JavaScript.
        // Wait for the page to load, timeout after 10 seconds
        (new WebDriverWait(driver, 10)).until(new ExpectedCondition<Boolean>() {
            public Boolean apply(WebDriver d) {
                return d.getTitle().toLowerCase().startsWith("cheese!");
            }
        });

        // Should see: "cheese! - Google Search"
        System.out.println("Page title is: " + driver.getTitle());

        //Close the browser
        driver.quit();
    }

}

Le istruzioni sembrano fermarsi qui. Cosa faccio dopo? Come faccio a gestirlo?

Aggiornamento 11/12/2017

Ora sto facendo qualche progresso con questo. Il progetto è finalmente in esecuzione, anche se non sta ancora eseguendo il test.

Questo è il mio ultimo file POM:

<?xml version="1.0" encoding="UTF-8"?>
<project xmlns="http://maven.apache.org/POM/4.0.0"
             xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"

        </dependency>
    </dependencies>
     <build>
        <plugins>
          <plugin>
            <groupId>org.apache.maven.plugins</groupId>

            <configuration>
              <includes>
                <include>Selenium2Example.java</include>
              </includes>
            </configuration>
          </plugin>
        </plugins>
      </build>
</project>

Questo è il codice java:

//package org.openqa.selenium.example;

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.ExpectedCondition;
import org.openqa.selenium.support.ui.WebDriverWait;

public class Selenium2Example {
 public static void main(String[] args) {
        // Create a new instance of the Firefox driver
        // Notice that the remainder of the code relies on the interface, 
        // not the implementation.
        System.out.println("Hello world!");
        System.setProperty("webdriver.gecko.driver", 
"C:\\Users\\sstaple\\Downloads\\geckodriver\\geckodriver.exe");

        WebDriver driver = new FirefoxDriver();

        // And now use this to visit Google
        driver.get("http://www.google.com");
        // Alternatively the same thing can be done like this
        // driver.navigate().to("http://www.google.com");

        // Find the text input element by its name
        WebElement element = driver.findElement(By.name("q"));

        // Enter something to search for
        element.sendKeys("Cheese!");

        // Now submit the form. WebDriver will find the form for us from the 
element
        element.submit();

        // Check the title of the page
        System.out.println("Page title is: " + driver.getTitle());

        // Google's search is rendered dynamically with JavaScript.
        // Wait for the page to load, timeout after 10 seconds
        (new WebDriverWait(driver, 10)).until(new ExpectedCondition<Boolean>
() {
            public Boolean apply(WebDriver d) {
                return d.getTitle().toLowerCase().startsWith("cheese!");
            }
        });

        // Should see: "cheese! - Google Search"
        System.out.println("Page title is: " + driver.getTitle());

        //Close the browser
        driver.quit();
    }

}

Questo era il risultato dell'esecuzione di mvn install nel prompt dei comandi:

Come per il blocco di codice che hai condiviso tutto sembra a posto. Ma ancora una volta come hai detto org.seleniumhq.selenium selenium-server 3.0.1 è necessario scaricare obbligatoriogeckodriver binario da questo site e inseriscilo nel tuo sistema. Successivamente nel tuo blocco di codice devi menzionare come segue :

System.setProperty("webdriver.gecko.driver", "C:\\path\\to\\geckodriver.exe");
WebDriver driver = new FirefoxDriver();

Fasi di esecuzione:

  1. Salva il Selenium2Example.java e il pom.xml file
  2. Nella Package Explorer, Right Click su pom.xml, seleziona Run AS e selezionare Maven clean
  3. Nella Package Explorer, Right Click su pom.xml, seleziona Run AS e selezionare Maven install
  4. Nella Package Explorer, Right Click su pom.xml, seleziona Run AS e selezionare Maven test

Aggiornamento 1

Come stai vedendo l'errore come 'selection does not contain a main type', assicurarsi che il file .java sia all'interno \ProjectSpace\src\test\java\

Aggiornamento 2

Come te vedi ancora No sources to compile, come ultima risorsa, Clean tutto il tuo Projects all'interno del tuo IDE, Close il IDE, Delete la cartella m2 (MAVEN_HOME) dal sistema forzatamente. Prendi un System Reboot. prova a Execute tu Test. Inoltre dalla riga di comando anche tu puoi fare un mvn clean, mvn install e mvn test
