os.name:'Mac os X'

os.arch:'x86_64'

os.version:'10.12.6'

java.version:'1.8.0_131'

Firefox版本56.0.1（64位）

壁虎驱动程序最新版本0.19.0

错误显示失败： org.openqa.selenium.SessionNotCreatedException:尝试运行命令 没有建立联系

我尝试了不同的方法来解决它，但总是出现同样的错误。 1.将所有selenium测试驱动程序更新为最新版本 2.指定目录导出路径=$PATH driverDir

您的问题在于：

@After
    public void test_Cleaning(){
        System.out.println("Closing Browser");
        baseURL = null;
        driver.close();
        driver.quit();
    }

仅使用

close（）

尝试。 解释得很好。

您有什么版本的Firefox？确保它至少是最新的firefox，我还没有在mac上尝试firefox nighty，@Hac，如何在mac上调用firefox nighty？你有什么版本的firefox？确保它至少是最新的firefox，我还没有在mac上尝试firefox nighty，@Hac，如何在mac上调用firefox nighty？
