無法啓動新的瀏覽器會話：org.openqa.selenium.server.RemoteCommandException：在會話null上啓動瀏覽器時出錯

我在做什麼？

步驟1：啓動轂

集線器是中心點將接收所有的測試請求和分發它們的正確節點。

打開命令提示符並導航到您複製了selenium-server-standalone文件的目錄。鍵入以下命令：

java -jar selenium-server-standalone-2.14.0.jar -role hub

第2步：啓動節點

不管你是否要運行新的webdriver功能在一個網格，或使用Selenium 1 RC功能一格，或兩者同時，您使用相同的selenium-server-standalone jar文件來啓動節點。

java -jar selenium-server-standalone-2.14.0.jar -role node -hub http://localhost:44444/grid/register（44444這裏是我工作的環境）

Answer 1

這是由於硒和Firefox之間的兼容性問題。

您需要升級到最新的硒服務器2.44。

Answer 2

是的！正如alec [xe建議這是由於Firefox和硒之間的兼容性問題。對於高於30的Firefox版本，您必須使用硒2.44版本。 Here's硒的更新日誌請看看，並決定哪個版本的硒將滿足您的要求。
