Synopsis

WebDriver sessions

newtype WD a Source

A monadic interface to the WebDriver server. This monad is simply a state monad transformer over IO, threading session information between sequential webdriver commands

Constructors

WD (StateT WDSession IO a) 

data WDSession Source

The local state of a WebDriver session. This structure is passed implicitly through all WD computations

Constructors

WDSession 

Fields

wdSessHost :: ByteString
 
wdSessPort :: Int
 
wdSessBasePath :: ByteString
 
wdSessId :: Maybe SessionId

An opaque reference identifying the session to use with WD commands. A value of Nothing indicates that a session hasn't been created yet. Sessions can be created within WD via createSession, or created automatically with runSession

wdSessHist :: [(Request, Response ByteString)]

The complete history of HTTP requests and responses, most recent first.

wdSessHistUpdate :: (Request, Response ByteString) -> [(Request, Response ByteString)] -> [(Request, Response ByteString)]

Update function used to append new entries to session history

wdSessHTTPManager :: Manager

HTTP Manager used for connection pooling by the http-client library.

newtype SessionId Source

An opaque identifier for a WebDriver session. These handles are produced by the server on session creation, and act to identify a session in progress.

Constructors

SessionId Text 

WebDriver configuration

data WDConfig Source

WebDriver session configuration

Constructors

WDConfig 

Fields

wdHost :: String

Host name of the WebDriver server for this session (default 127.0.0.1)

wdPort :: Int

Port number of the server (default 4444)

wdCapabilities :: Capabilities

Capabilities to use for this session

wdKeepSessHist :: Bool

Whether or not we should keep a history of HTTP requests/responses

By default, only the last request/response pair is stored (O(1) heap consumption). Enable this option for more detailed debugging info for HTTP requests.

wdBasePath :: String

Base path for all API requests (default "wdhub")

wdHTTPManager :: Maybe Manager

Use the given http-client Manager instead of the default

Instances

defaultConfig :: WDConfig Source

A default session config connects to localhost on port 4444, and hasn't been initialized server-side. This value is the same as def but with a less polymorphic type.

Capabilities

data Capabilities Source

A structure describing the capabilities of a session. This record serves dual roles.

  • It's used to specify the desired capabilities for a session before it's created. In this usage, fields that are set to Nothing indicate that we have no preference for that capability.
  • When received from the server , it's used to describe the actual capabilities given to us by the WebDriver server. Here a value of Nothing indicates that the server doesn't support the capability. Thus, for Maybe Bool fields, both Nothing and Just False indicate a lack of support for the desired capability.

Constructors

Capabilities 

Fields

browser :: Browser

Browser choice and browser specific settings.

version :: Maybe String

Constructors

Windows 
XP 
Vista 
Mac 
Linux 
Unix 
Any 

data ProxyType Source

Manual

Manually specify proxy hosts as hostname:port strings. Note that behavior is undefined for empty strings.

Browser-specific capabilities

data Browser Source

This constructor simultaneously specifies which browser the session will use, while also providing browser-specific configuration. Default configuration is provided for each browser by firefox, chrome, opera, ie, etc.

This library uses firefox as its Default browser configuration, when no browser choice is specified.

Constructors

Firefox 

Fields

ffProfile :: Maybe (PreparedProfile Firefox)

The firefox profile to use. If Nothing, a default temporary profile is automatically created and used.

ffLogPref :: LogLevel

Firefox logging preference

ffBinary :: Maybe FilePath

Server-side path to Firefox binary. If Nothing, use a sensible system-based default.

Chrome 

Fields

chromeDriverVersion :: Maybe String

Version of the Chrome Webdriver server server to use

for more information on chromedriver see http://code.google.com/p/selenium/wiki/ChromeDriver

chromeBinary :: Maybe FilePath

Server-side path to Chrome binary. If Nothing, use a sensible system-based default.

chromeOptions :: [String]

A list of command-line options to pass to the Chrome binary.

chromeExtensions :: [ChromeExtension]

A list of extensions to use.

IE 

Fields

ieIgnoreProtectedModeSettings :: Bool

Whether to skip the protected mode check. If set, tests may become flaky, unresponsive, or browsers may hang. If not set, and protected mode settings are not the same for all zones, an exception will be thrown on driver construction.

ieIgnoreZoomSetting :: Bool

Indicates whether to skip the check that the browser's zoom level is set to 100%. Value is set to false by default.

ieInitialBrowserUrl :: Maybe Text

Allows the user to specify the initial URL loaded when IE starts. Intended to be used with ignoreProtectedModeSettings to allow the user to initialize IE in the proper Protected Mode zone. Using this capability may cause browser instability or flaky and unresponsive code. Only "best effort" support is provided when using this capability.

ieElementScrollBehavior :: IEElementScrollBehavior

Allows the user to specify whether elements are scrolled into the viewport for interaction to align with the top or bottom of the viewport. The default value is to align with the top of the viewport.

ieEnablePersistentHover :: Bool

Determines whether persistent hovering is enabled (true by default). Persistent hovering is achieved by continuously firing mouse over events at the last location the mouse cursor has been moved to.

ieEnableElementCacheCleanup :: Bool

Determines whether the driver should attempt to remove obsolete elements from the element cache on page navigation (true by default). This is to help manage the IE driver's memory footprint , removing references to invalid elements.

ieRequireWindowFocus :: Bool

Determines whether to require that the IE window have focus before performing any user interaction operations (mouse or keyboard events). This capability is false by default, but delivers much more accurate native events interactions.

ieBrowserAttachTimeout :: Integer

The timeout, in milliseconds, that the driver will attempt to locate and attach to a newly opened instance of Internet Explorer . The default is zero, which indicates waiting indefinitely.

ieLogFile :: Maybe FilePath

The path to file where server should write log messages to. By default it writes to stdout.

ieLogLevel :: IELogLevel

The log level used by the server. Defaults to IELogFatal

ieHost :: Maybe Text

The address of the host adapter on which the server will listen for commands.

ieExtractPath :: Maybe Text

The path to the directory used to extract supporting files used by the server. Defaults to the TEMP directory if not specified.

ieSilent :: Bool

Suppresses diagnostic output when the server is started.

ieForceCreateProcess :: Bool

Forces launching Internet Explorer using the CreateProcess API. If this option is not specified, IE is launched using the IELaunchURL, if it is available. For IE 8 and above, this option requires the TabProcGrowth registry value to be set to 0.

ieSwitches :: Maybe Text

Specifies command-line switches with which to launch Internet Explorer. This is only valid when used with the forceCreateProcess.

Opera 

Fields

operaBinary :: Maybe FilePath

Server-side path to the Opera binary

operaProduct :: Maybe String

Which Opera product we're using, e.g. "desktop", "core"

operaDetach :: Bool

Whether the Opera instance should stay open after we close the session. If false, closing the session closes the browser.

operaAutoStart :: Bool

Whether to auto-start the Opera binary. If false, OperaDriver will wait for a connection from the browser. By default this is True.

operaIdle :: Bool

Whether to use Opera's alternative implicit wait implementation. It will use an in-browser heuristic to guess when a page has finished loading. This feature is experimental, and disabled by default.

operaDisplay :: Maybe Int

(*nix only) which X display to use.

operaLauncher :: Maybe FilePath

Path to the launcher binary to use. The launcher is a gateway between OperaDriver and the Opera browser. If Nothing, OperaDriver will use the launcher supplied with the package.

operaPort :: Maybe Word16

The port we should use to connect to Opera. If Just 0 , use a random port. If Nothing, use the default Opera port. The default opera constructor uses Just 0, since Nothing is likely to cause "address already in use" errors.

operaHost :: Maybe String

The host Opera should connect to. Unless you're starting Opera manually you won't need this.

operaOptions :: Maybe String

Command-line arguments to pass to Opera.

operaLogFile :: Maybe FilePath
