Properties for Selenium Grid Hub/Node Config

This documentation is available via the Selenium standalone uber jar itself.

java -jar selenium-server-standalone-3.3.1.jar -help

Usage: <main class> [options]  Options:    --version, -version       Displays the version and exits.       Default: false    -browserTimeout       <Integer> in seconds : number of seconds a browser session is allowed to       hang while a WebDriver command is running (example: driver.get(url)). If the       timeout is reached while a WebDriver command is still processing, the session       will quit. Minimum value is 60. An unspecified, zero, or negative value means       wait indefinitely.       Default: 0    -debug       <Boolean> : enables LogLevel.FINE.       Default: false    -jettyThreads, -jettyMaxThreads       <Integer> : max number of threads for Jetty. An unspecified, zero, or       negative value means the Jetty default value (200) will be used.    -log       <String> filename : the filename to use for logging. If omitted, will log       to STDOUT    -port       <Integer> : the port number the server will use.       Default: 4444    -role       <String> options are [hub], [node], or [standalone].       Default: standalone    -timeout, -sessionTimeout       <Integer> in seconds : Specifies the timeout before the server       automatically kills a session that hasn't had any activity in the last X seconds. The       test slot will then be released for another test to use. This is typically       used to take care of client crashes. For grid hub/node roles, cleanUpCycle       must also be set.       Default: 1800

For help on the hub role

java -jar selenium-server-standalone-3.3.1.jar -role hub -help

Usage: <main class> [options]  Options:    --version, -version       Displays the version and exits.       Default: false    -browserTimeout       <Integer> in seconds : number of seconds a browser session is allowed to       hang while a WebDriver command is running (example: driver.get(url)). If the       timeout is reached while a WebDriver command is still processing, the session       will quit. Minimum value is 60. An unspecified, zero, or negative value means       wait indefinitely.       Default: 0    -matcher, -capabilityMatcher       <String> class name : a class implementing the CapabilityMatcher       interface. Specifies the logic the hub will follow to define whether a request can       be assigned to a node. For example, if you want to have the matching process       use regular expressions instead of exact match when specifying browser       version. ALL nodes of a grid ecosystem would then use the same capabilityMatcher,       as defined here.       Default: org.openqa.grid.internal.utils.DefaultCapabilityMatcher@64a294a6    -cleanUpCycle       <Integer> in ms : specifies how often the hub will poll running proxies       for timed-out (i.e. hung) threads. Must also specify "timeout" option       Default: 5000    -custom       <String> : comma separated key=value pairs for custom grid extensions.       NOT RECOMMENDED -- may be deprecated in a future revision. Example: -custom       myParamA=Value1,myParamB=Value2       Default: {}    -debug       <Boolean> : enables LogLevel.FINE.       Default: false    -host       <String> IP or hostname : usually determined automatically. Most commonly       useful in exotic network configurations (e.g. network with VPN)    -hubConfig       <String> filename: a JSON file (following grid2 format), which defines       the hub properties    -jettyThreads, -jettyMaxThreads       <Integer> : max number of threads for Jetty. An unspecified, zero, or       negative value means the Jetty default value (200) will be used.    -log       <String> filename : the filename to use for logging. If omitted, will log       to STDOUT    -maxSession       <Integer> max number of tests that can run at the same time on the node,       irrespective of the browser used    -newSessionWaitTimeout       <Integer> in ms : The time 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 attempting to start a browser. An unspecified, zero, or negative       value means wait indefinitely.       Default: -1    -port       <Integer> : the port number the server will use.       Default: 4444    -prioritizer       <String> class name : a class implementing the Prioritizer interface.       Specify a custom Prioritizer if you want to sort the order in which new session       requests are processed when there is a queue. Default to null ( no priority = FIFO       )    -role       <String> options are [hub], [node], or [standalone].       Default: hub    -servlet, -servlets       <String> : list of extra servlets the grid (hub or node) will make       available. Specify multiple on the command line: -servlet tld.company.ServletA       -servlet tld.company.ServletB. The servlet must exist in the path:       /grid/admin/ServletA /grid/admin/ServletB       Default: []    -timeout, -sessionTimeout       <Integer> in seconds : Specifies the timeout before the server       automatically kills a session that hasn't had any activity in the last X seconds. The       test slot will then be released for another test to use. This is typically       used to take care of client crashes. For grid hub/node roles, cleanUpCycle       must also be set.       Default: 1800    -throwOnCapabilityNotPresent       <Boolean> true or false : If true, the hub will reject all test requests       if no compatible proxy is currently registered. If set to false, the request       will queue until a node supporting the capability is registered with the grid.       Default: true    -withoutServlet, -withoutServlets       <String> : list of default (hub or node) servlets to disable. Advanced       use cases only. Not all default servlets can be disabled. Specify multiple on       the command line: -withoutServlet tld.company.ServletA -withoutServlet       tld.company.ServletB       Default: []

If the       timeout is reached while a WebDriver command is still processing, the session       will quit. Minimum value is 60. An unspecified, zero, or negative value means       wait indefinitely.       Default: 0    -capabilities, -browser       <String> : comma separated Capability values. Example: -capabilities       browserName=firefox,platform=linux -capabilities browserName=chrome,platform=linux       Default: [Capabilities [{seleniumProtocol=WebDriver, browserName=chrome, maxInstances=5}], Capabilities [{seleniumProtocol=WebDriver, browserName=firefox, maxInstances=5}], Capabilities [{seleniumProtocol=WebDriver, browserName=internet explorer, maxInstances=1}]]    -cleanUpCycle       <Integer> in ms : specifies how often the hub will poll running proxies       for timed-out (i.e. hung) threads.

Default: http://localhost:4444    -hubHost       <String> IP or hostname : the host address of the hub we're attempting to       register with. If -hub is specified the -hubHost is determined from it.    -hubPort       <Integer> : the port of the hub we're attempting to register with. If       -hub is specified the -hubPort is determined from it.    -id       <String> : optional unique identifier for the node. Defaults to the url       of the remoteHost, when not specified.    -jettyThreads, -jettyMaxThreads       <Integer> : max number of threads for Jetty. An unspecified, zero, or       negative value means the Jetty default value (200) will be used.    -log       <String> filename : the filename to use for logging. If omitted, will log       to STDOUT    -maxSession       <Integer> max number of tests that can run at the same time on the node,       irrespective of the browser used       Default: 5    -nodeConfig       <String> filename : JSON configuration file for the node.

Default is       [org.openqa.grid.selenium.proxy.DefaultRemoteProxy].       Default: org.openqa.grid.selenium.proxy.DefaultRemoteProxy    -register       if specified, node will attempt to re-register itself automatically with       its known grid hub if the hub becomes unavailable.       Default: true    -registerCycle       <Integer> in ms : specifies how often the node will try to register       itself again. Allows administrator to restart the hub without restarting (or       risk orphaning) registered nodes. Must be specified with the "-register"       option.       Default: 5000    -role       <String> options are [hub], [node], or [standalone].       Default: node    -servlet, -servlets       <String> : list of extra servlets the grid (hub or node) will make       available.

The       test slot will then be released for another test to use. This is typically       used to take care of client crashes. For grid hub/node roles, cleanUpCycle       must also be set.       Default: 1800    -unregisterIfStillDownAfter       <Integer> in ms : if the node remains down for more than       [unregisterIfStillDownAfter] ms, it will stop attempting to re-register from the hub.       Default: 60000    -withoutServlet, -withoutServlets       <String> : list of default (hub or node) servlets to disable. Advanced       use cases only. Not all default servlets can be disabled.
