selenium_server_available {selenium}

Is a selenium server instance running?

Description

selenium_server_available() returns TRUE if a Selenium server is running on a given port and host. wait_for_selenium_available() waits for the Selenium server to become available for a given time.

get_server_status(), when given a port and host, figures out whether a Selenium server instance is running, and if so, returns its status. This is used by selenium_server_available() to figure out if the server is running.

Usage

selenium_server_available(
  port = 4444L,
  host = "localhost",
  verbose = FALSE,
  timeout = 20
)

wait_for_selenium_available(
  max_time = 60,
  port = 4444L,
  host = "localhost",
  verbose = FALSE,
  timeout = 20,
  error = FALSE
)

get_server_status(
  port = 4444L,
  host = "localhost",
  verbose = FALSE,
  timeout = 20
)

Arguments

port

The port that the Selenium server is using, so we can connect to it.

host

The host that the Selenium server is running on. This is usually 'localhost' (i.e. Your own machine).

verbose

Whether to print information about the web request that is sent.

timeout

How long to wait for a request to recieve a response before throwing an error.

max_time

The amount of time to wait for the Selenium server to become available.

error

Whether to throw an error if the web request throws an error after the timeout is exceeded. By default, a logical value is always returned.

Value

selenium_server_available() returns TRUE if a Selenium server is running, and FALSE otherwise, and wait_for_selenium_available() returns the same thing.

get_server_status() returns a list that can (but may not always) contain the following fields:

• ready: Whether the server is ready to be connected to. This should always be returned by the server.

• message: A message about the status of the server.

• uptime: How long the server has been running.

• nodes: Information about the slots that the server can take.
