アクセスしようとしているページの要素を見つけるために HtmlUnitDriver を取得できません。一方、WebDriver は正常に動作します。どちらも同じ方法を使用しています。これが私のコードです：

import java.util.logging.*;
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.htmlunit.HtmlUnitDriver;
import com.gargoylesoftware.htmlunit.BrowserVersion;


public class Main {


    public static void main(String[]args)
    {
        FirefoxDriver driver2=new FirefoxDriver();

        HtmlUnitDriver driver=new HtmlUnitDriver(BrowserVersion.FIREFOX_10);
        driver.setJavascriptEnabled(true);
        Logger.getLogger("com.gargoylesoftware").setLevel(Level.OFF);

        runTest(driver2); //works
        runTest(driver);  //does not work
    }

    public static void runTest(WebDriver driver)
    {
        driver.get("http://10.3.1.164");
        WebElement elem=driver.findElement(By.xpath("//td[2]/input"));
        assert elem.isDisplayed();
        System.out.println(driver.getTitle());
    }
}

スタックトレースは次のとおりです。

Exception in thread "main" org.openqa.selenium.NoSuchElementException: Unable to     locate a node using //td[2]/input

私はそれを考え出した。要素が読み込まれるのを待つだけでした。これがコードです。

import java.io.IOException;
import java.net.MalformedURLException;
import java.util.logging.*;
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.htmlunit.*;
import org.openqa.selenium.support.ui.ExpectedConditions;
import org.openqa.selenium.support.ui.WebDriverWait;
import com.gargoylesoftware.htmlunit.BrowserVersion;
import com.gargoylesoftware.htmlunit.FailingHttpStatusCodeException;

public class Main {


public static void main(String[]args) throws FailingHttpStatusCodeException, MalformedURLException, IOException
{
    FirefoxDriver driver2=new FirefoxDriver();

    HtmlUnitDriver driver=new HtmlUnitDriver(BrowserVersion.FIREFOX_3_6);

    driver.setJavascriptEnabled(true);
    Logger.getLogger("com.gargoylesoftware").setLevel(Level.OFF);

    runTest(driver2); //works
    runTest(driver);  //does not work
}

public static void runTest(WebDriver driver)
{
    driver.get("http://10.3.1.164");
    WebElement elem=(new WebDriverWait(driver, 10)) //added this line
    .until(ExpectedConditions.presenceOfElementLocated(By.xpath("//td[2]/input")));
    System.out.println(elem.getAttribute("id"));
    assert elem.isDisplayed();
    System.out.println(driver.getTitle());
}
}
