我是使用 Selenium Grid 的新手。我尝试在 FF 中为特定节点（5556）打开浏览器，同样遵循以下步骤
- 启动集线器
java -jar selenium-server-standalone-2.33.0.jar -role hub
- 在 FF 中为特定节点打开浏览器 (5556)
java -jar selenium-server-standalone-2.33.0.jar -role webdriver -hub http://localhost:4444/grid/register -port 5556 -browser browserName-firefox
它抛出一个错误

INFO: Adding browserName-firefox
Error building the config :-browser format is key1=value1,key2=value2 browserNam
e-firefox doesn't follow that format.
Usage :
-hubConfig:
(hub) a JSON file following grid2 format that defines the hub
properties.
-nodeTimeout:
(node) <XXXX> the timeout in seconds before the hub
automatically ends a test that hasn't had any activity in the
last X seconds. The browser will be released for another test to
use. This typically takes care of the client crashes.
-throwOnCapabilityNotPresent:
(hub) <true | false> default to true. If true, the hub will
reject test requests right away if no proxy is currently
registered that can host that capability.Set it to false to have
the request queued until a node supporting the capability is
added to the grid.
-maxSession:
(node) max number of tests that can run at the same time on the
node, independently of the browser used.
-hub:
(node) <http://localhost:4444/grid/register> : the url that will
be used to post the registration request. This option takes
precedence over -hubHost and -hubPort options.
-hubPort:
(node) <xxxx> : the port listened by a hub the registration
request should be sent to. Default to 4444. Option -hub takes
precedence over this option.
-registerCycle:
(node) how often in ms the node will try to register itself
again.Allow to restart the hub without having to restart the
nodes.
-capabilityMatcher:
(hub) a class implementing the CapabilityMatcher interface.
Defaults to
org.openqa.grid.internal.utils.DefaultCapabilityMatcher. Specify
the logic the hub will follow to define if a request can be
assigned to a node.Change this class if you want to have the
matching process use regular expression instead of exact match
for the version of the browser for instance. All the nodes of a
grid instance will use the same matcher, defined by the registry.
-nodeStatusCheckTimeout:
(node) in ms. Connection and socket timeout which is used for
node alive check.
-port:
(hub & node) <xxxx> : the port the remote/hub will listen on.
Default to 4444.
-hubHost:
(node) <IP | hostname> : the host address of a hub the
registration request should be sent to. Default to localhost.
Option -hub takes precedence over this option.
-newSessionWaitTimeout:
(hub) <XXXX>. Default to no timeout ( -1 ) the time in ms after
which a new test waiting for a node to become available will time
out.When that happens, the test will throw an exception before
starting a browser.
-nodePolling:
(node) in ms. Interval between alive checks of node how often the
hub checks if the node is still alive.
-host:
(hub & node) <IP | hostname> : usually not needed and determined
automatically. For exotic network configuration, network with
VPN, specifying the host might be necessary.
-downPollingLimit:
(node) node is marked as down after downPollingLimit alive
checks.
-unregisterIfStillDownAfter:
(node) in ms. If the node remains down for more than
unregisterIfStillDownAfter millisec, it will disappear from the
hub.Default is 1min.
-cleanupCycle:
(node) <XXXX> in ms. How often a proxy will check for timed out
thread.
-nodeConfig:
(node) a JSON file following grid2 format that defines the node
properties.
-prioritizer:
(hub) a class implementing the Prioritizer interface. Default to
null ( no priority = FIFO ).Specify a custom prioritizer if you
need the grid to process the tests from the CI, or the IE tests
first for instance.
-servlets:
(hub & node) <com.mycompany.MyServlet,com.mycompany.MyServlet2>
to register a new servlet on the hub/node. The servlet will
accessible under the path /grid/admin/MyServlet
/grid/admin/MyServlet2
-proxy:
(node) the class that will be used to represent the node. By
default org.openqa.grid.selenium.proxy.DefaultRemoteProxy.
-browserTimeout:
(hub/node) The timeout in seconds a browser can hang
-grid1Yml:
(hub) a YML file following grid1 format.
-role:
<hub|node> (default is no grid, just run an RC/webdriver server).
When launching a node, the parameters will be forwarded to the
server on the node, so you can use something like -role node
-trustAllSSLCertificates. In that case, the SeleniumServer will
be launch with the trustallSSLCertificates option.
org.openqa.grid.common.exception.GridConfigurationException: -browser format is
key1=value1,key2=value2 browserName-firefox doesn't follow that format.
