Selenium Grid を使用して Web ページのテストを行っています。セレン ハブ:

java -jar selenium-server-standalone-2.25.0.jar -role hub

セレンノード:

java -jar selenium-server-standalone-2.25.0.jar -role node  -hub http://192.168.55.209:4444/grid/register browser browserName=firefox,platform=WINDOWS

そして、ノードはハブに正常に登録されました。次のように使用したJavaコードの場合：

@Before
public void setUp() throws Exception,MalformedURLException, IOException {
    DesiredCapabilities browser = DesiredCapabilities.firefox();
    browser.setPlatform(Platform.WINDOWS);
    try{
    driver=new RemoteWebDriver(new URL("http://192.168.55.209:4444/wd/hub"),browser);
                } finally{
                    if (driver != null) {
                                 driver.quit();
                    }
                }

しかし、コンパイラが到達すると:

driver.get(url);

次のようなエラーメッセージが表示されますが、問題は見つかりませんでした。

あなたの設定には がありますが、前browser browserName=firefoxの記号 " " を忘れたので、 : である必要があります。これは問題になる可能性があります。webdriver はエラーを表示しませんが、その特定の " " を実際の Firefox ブラウザーに関連付けることはできません。-browser-browser browserName=firefoxfirefox
