NAME

Firefox::Marionette::Capabilities - Represents Firefox Capabilities retrieved using the Marionette protocol

VERSION

Version 1.62

SYNOPSIS

use Firefox::Marionette();
use v5.10;

my $firefox = Firefox::Marionette->new( capabilities => Firefox::Marionette::Capabilities->new( accept_insecure_certs => 0 ) );
if ($firefox->capabilities->accept_insecure_certs()) {
    say "Browser will now ignore certificate failures";
}

DESCRIPTION

This module handles the implementation of Firefox Capabilities using the Marionette protocol

SUBROUTINES/METHODS

accept_insecure_certs

indicates whether untrusted and self-signed TLS certificates are implicitly trusted on navigation for the duration of the session.

browser_name

returns the browsers name. For example 'firefox'

browser_version

returns the version of firefox

enumerate

This method returns a list of strings describing the capabilities that this version of Firefox supports.

moz_accessibility_checks

returns the current accessibility (a11y) value

moz_build_id

returns the Firefox BuildId

moz_headless

returns whether the browser is running in headless mode

moz_process_id

returns the process id belonging to the browser

moz_profile

returns the directory that contains the browsers profile

moz_shutdown_timeout

returns the value of moz:shutdownTimeout (aka the value of config toolkit.asyncshutdown.crash_timeout)

moz_use_non_spec_compliant_pointer_origin

returns a boolean value to indicate how the pointer origin for an action command will be calculated.

With Firefox 59 the calculation will be based on the requirements by the WebDriver specification. This means that the pointer origin is no longer computed based on the top and left position of the referenced element, but on the in-view center point. With Firefox 116, this capability is no longer supported.

To temporarily disable the WebDriver conformant behavior use 0 as value for this capability.

Please note that this capability exists only temporarily, and that it will be removed once all Selenium bindings can handle the new behavior.

moz_webdriver_click

returns a boolean value to indicate which kind of interactability checks to run when performing a click or sending keys to an elements. For Firefoxen prior to version 58.0 some legacy code as imported from an older version of FirefoxDriver was in use.

With Firefox 58 the interactability checks as required by the WebDriver specification are enabled by default. This means geckodriver will additionally check if an element is obscured by another when clicking, and if an element is focusable for sending keys.

Because of this change in behaviour, we are aware that some extra errors could be returned. In most cases the test in question might have to be updated so it's conform with the new checks. But if the problem is located in geckodriver, then please raise an issue in the issue tracker.

To temporarily disable the WebDriver conformant checks use 0 as value for this capability.

Please note that this capability exists only temporarily, and that it will be removed once the interactability checks have been stabilized.

new

accepts a hash as a parameter. Allowed keys are below;

  • accept_insecure_certs - Indicates whether untrusted and self-signed TLS certificates are implicitly trusted on navigation for the duration of the session. Allowed values are 1 or 0. Default is 0.

  • moz_accessibility_checks - run a11y checks when clicking elements. Allowed values are 1 or 0. Default is 0.

  • moz_headless - the browser should be started with the -headless option. moz_headless is only supported in Firefox 56+

  • moz_use_non_spec_compliant_pointer_origin - a boolean value to indicate how the pointer origin for an action command will be calculated.

    With Firefox 59 the calculation will be based on the requirements by the WebDriver specification. This means that the pointer origin is no longer computed based on the top and left position of the referenced element, but on the in-view center point.

    To temporarily disable the WebDriver conformant behavior use 0 as value for this capability.

    Please note that this capability exists only temporarily, and that it will be removed once all Selenium bindings can handle the new behavior.

  • page_load_strategy - defines the page load strategy for the upcoming browser session.

  • proxy - describes the proxy setup for the upcoming browser session.

  • strict_file_interactability - a boolean value to indicate if interactability checks will be applied to <input type=file>. Allowed values are 1 or 0. Default is 0.

  • timeouts - describes the timeouts imposed on certain session operations.

  • unhandled_prompt_behavior - defines what firefox should do on encountering a user prompt. There are a range of allowed values, including "dismiss", "accept", "dismiss and notify", "accept and notify" and "ignore".

This method returns a new capabilities object.

page_load_strategy

returns the page load strategy to use for the duration of the session. The page load strategy corresponds to the readyState and may be one of the following values;

  • normal - Wait for the document and all sub-resources have finished loading. The corresponding readyState is "complete". The load event is about to fire. This strategy is the default value.

  • eager - Wait for the document to have finished loading and have been parsed. Sub-resources such as images, stylesheets and frames are still loading. The corresponding readyState is "interactive".

  • none - return immediately after starting navigation. The corresponding readyState is "loading".

platform_name

returns the operating system name. For example 'linux', 'darwin' or 'windows_nt'.

proxy

returns the current proxy object

platform_version

returns the operation system version. For example '4.14.11-300.fc27.x86_64', '17.3.0' or '10.0'

rotatable

does this version of firefox have a rotatable screen such as Android Fennec.

set_window_rect

returns true if Firefox fully supports setWindowRect, otherwise it returns false.

strict_file_interactability

returns the current value of strictFileInteractability

timeouts

returns the current timeouts object

unhandled_prompt_behavior

returns the current value of unhandledPromptBehavior.

DIAGNOSTICS

None.

CONFIGURATION AND ENVIRONMENT
