SeleniumSession: Start a Selenium Client session
In selenium: Low-Level Browser Automation Interface

SeleniumSessionR Documentation

Start a Selenium Client session

Description

This class represents the client to a Selenium session. It will only work if a Selenium server instance is running. If you get an error, use selenium_server_available() to check if a server is running. See the package README for more information, or use selenium_server() to try and start a server automatically.

Public fields

id

The id of the session, generated when the session is started.

browser

The browser that the session is using.

port

The port that the session is using.

host

The host that the session is running on.

Methods

Public methods

Method new()

Create a Selenium session: opening a browser which can be controlled by the Selenium client.

Usage
SeleniumSession$new(
  browser = "firefox",
  port = 4444L,
  host = "localhost",
  verbose = FALSE,
  capabilities = NULL,
  request_body = NULL,
  timeout = 20
)
Arguments
browser

The name of the browser to use (e.g. "chrome", "firefox", "edge").

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 the web requests that are being sent and any responses.

capabilities

A list of capabilities to pass to the Selenium server, to combine with the defaults generated using browser. See chrome_options(), firefox_options(), and edge_options().

request_body

A list of request body parameters to pass to the Selenium server. Overrides capabilities.

timeout

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

Returns

A SeleniumSession object.

Examples
\dontrun{
session <- SeleniumSession$new(verbose = TRUE)

session$close()
}

Method create_webelement()

Create a WebElement object using the parameters of the current session.

Usage
SeleniumSession$create_webelement(id)
Arguments
id

The element id.

Returns

A WebElement object.

Examples
\dontrun{
session <- SeleniumSession$new()

element <- session$find_element(using = "css selector", value = "*")

element2 <- session$create_webelement(id = element$id)

session$close()
}

Method create_shadowroot()

Create a ShadowRoot object using the parameters of the current session.

Usage
SeleniumSession$create_shadowroot(id)
Arguments
id

The shadow root id.

Returns

A ShadowRoot object.

Examples
\dontrun{
session <- SeleniumSession$new()

shadow_root <- session$create_shadowroot(id = "foo")

session$close()
}

Method close()

Close the current session. Once a session is closed, its methods will no longer work. However, the Selenium server will still be running.

Usage
SeleniumSession$close(timeout = 20)
Arguments
timeout

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

Returns

TRUE if the session was closed successfully, or FALSE if the session was already closed.

Examples
\dontrun{
session <- SeleniumSession$new()

session$close()
}

Method status()

Get the status of the Selenium server. Unlike all other methods, this method is independent of the session itself (meaning it can be used even after SeleniumSession$close() is called). It is identical to get_server_status(), but uses the host, port and verbose options passed to the session, for convenience.

Usage
SeleniumSession$status(timeout = 20)
Arguments
timeout

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

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.

Examples
\dontrun{
session <- SeleniumSession$new()

session$status()

session$close()

session$status()
}

Method get_timeouts()

Get the timeouts of the current session. There are three types of timeouts:

  • session script timeout: The amount of time that the server will wait for scripts to run. Defaults to 3 seconds.

  • page load timeout: The amount of time that the server will wait for the page to load. Defaults to 30 seconds.
