marionette_driver package¶

Submodules¶

marionette_driver.addons module¶

exception marionette_driver.addons.AddonInstallException(message=None, cause=None, stacktrace=None)¶: Bases: marionette_driver.errors.MarionetteException

class marionette_driver.addons.Addons(marionette)¶

Bases: object

An API for installing and inspecting addons during Gecko runtime. This is a partially implemented wrapper around Gecko’s AddonManager API.

For example:

from marionette_driver.addons import Addons
addons = Addons(marionette)
addons.install("/path/to/extension.xpi")

install(path, temp=False)¶

Install a Firefox addon.

If the addon is restartless, it can be used right away. Otherwise a restart using restart() will be needed.

Parameters

path – A file path to the extension to be installed.
temp – Install a temporary addon. Temporary addons will automatically be uninstalled on shutdown and do not need to be signed, though they must be restartless.

Returns

The addon ID string of the newly installed addon.

Raises

AddonInstallException

uninstall(addon_id)¶

Uninstall a Firefox addon.

If the addon is restartless, it will be uninstalled right away. Otherwise a restart using restart() will be needed.

If the call to uninstall is resulting in a ScriptTimeoutException, an invalid ID is likely being passed in. Unfortunately due to AddonManager’s implementation, it’s hard to retrieve this error from Python.

Parameters: addon_id – The addon ID string to uninstall.

You can select which element to be checked for visibility by supplying a locator:

displayed = Wait(marionette).until(expected.element_displayed(By.ID, "foo"))

Or by supplying an element:

el = marionette.find_element(By.ID, "foo")
displayed = Wait(marionette).until(expected.element_displayed(el))

marionette_driver.localization module¶

class marionette_driver.localization.L10n(marionette)¶

Bases: object

An API which allows Marionette to handle localized content.

The localization of UI elements in Gecko based applications is done via entities and properties. For static values entities are used, which are located in .dtd files. Whereby for dynamically updated content the values come from .property files. Both types of elements can be identifed via a unique id, and the translated content retrieved.

For example:

from marionette_driver.localization import L10n
l10n = L10n(marionette)

l10n.localize_entity(["chrome://branding/locale/brand.dtd"], "brandShortName")
l10n.localize_property(["chrome://global/locale/findbar.properties"], "FastFind"))

localize_entity(dtd_urls, entity_id)¶

Retrieve the localized string for the specified entity id.

Parameters

dtd_urls – List of .dtd URLs which will be used to search for the entity.
entity_id – ID of the entity to retrieve the localized string for.

Returns

The localized string for the requested entity.

Raises

NoSuchElementException

localize_property(properties_urls, property_id)¶

Retrieve the localized string for the specified property id.

Parameters

properties_urls – List of .properties URLs which will be used to search for the property.
property_id – ID of the property to retrieve the localized string for.

Returns

The localized string for the requested property.

Raises

NoSuchElementException

Parameters: prefs – A dictionary whose keys are preference names.

execute_async_script(script, script_args=(), new_sandbox=True, sandbox='default', script_timeout=None)¶

Executes an asynchronous JavaScript script, and returns the result (or None if the script does return a value).

The script is executed in the context set by the most recent set_context() call, or to the CONTEXT_CONTENT context if set_context() has not been called.

Parameters

script – A string containing the JavaScript to execute.
script_args – An interable of arguments to pass to the script.
new_sandbox – If False, preserve global variables from the last execute_*script call. This is True by default, in which case no globals are preserved.
sandbox – A tag referring to the sandbox you wish to use; if you specify a new tag, a new sandbox will be created. If you use the special tag system, the sandbox will be created using the system principal which has elevated privileges.
script_timeout – Timeout in milliseconds, overriding the session’s default script timeout.

Usage example:

marionette.timeout.script = 10
result = self.marionette.execute_async_script('''
  // this script waits 5 seconds, and then returns the number 1
  let [resolve] = arguments;
  setTimeout(function() {
    resolve(1);
  }, 5000);
''')
assert result == 1

execute_script(script, script_args=(), new_sandbox=True, sandbox='default', script_timeout=None)¶

Executes a synchronous JavaScript script, and returns the result (or None if the script does return a value).

The script is executed in the context set by the most recent set_context() call, or to the CONTEXT_CONTENT context if set_context() has not been called.

Parameters

script – A string containing the JavaScript to execute.
script_args – An interable of arguments to pass to the script.
new_sandbox – If False, preserve global variables from the last execute_*script call. This is True by default, in which case no globals are preserved.
sandbox – A tag referring to the sandbox you wish to use; if you specify a new tag, a new sandbox will be created. If you use the special tag system, the sandbox will be created using the system principal which has elevated privileges.
script_timeout – Timeout in milliseconds, overriding the session’s default script timeout.

Simple usage example:

result = marionette.execute_script("return 1;")
assert result == 1

You can use the script_args parameter to pass arguments to the script:

result = marionette.execute_script("return arguments[0] + arguments[1];",
                                   script_args=(2, 3,))
assert result == 5
some_element = marionette.find_element(By.ID, "someElement")
sid = marionette.execute_script("return arguments[0].id;", script_args=(some_element,))
assert some_element.get_attribute("id") == sid

Scripts wishing to access non-standard properties of the window object must use window.wrappedJSObject:

result = marionette.execute_script('''
  window.wrappedJSObject.test1 = "foo";
  window.wrappedJSObject.test2 = "bar";
  return window.wrappedJSObject.test1 + window.wrappedJSObject.test2;
  ''')
assert result == "foobar"

Global variables set by individual scripts do not persist between script calls by default. If you wish to persist data between script calls, you can set new_sandbox to False on your next call, and add any new variables to a new ‘global’ object like this:

marionette.execute_script("global.test1 = 'foo';")
result = self.marionette.execute_script("return global.test1;", new_sandbox=False)
assert result == "foo"

find_element(method, target, id=None)¶

Returns an HTMLElement instance that matches the specified method and target in the current context.

An HTMLElement instance may be used to call other methods on the element, such as click(). If no element is immediately found, the attempt to locate an element will be repeated for up to the amount of time set by marionette_driver.timeout.Timeouts.implicit. If multiple elements match the given criteria, only the first is returned. If no element matches, a NoSuchElementException will be raised.

Parameters

method – The method to use to locate the element; one of: “id”, “name”, “class name”, “tag name”, “css selector”, “link text”, “partial link text” and “xpath”. Note that the “name”, “link text” and “partial link test” methods are not supported in the chrome DOM.
target – The target of the search. For example, if method = “tag”, target might equal “div”. If method = “id”, target would be an element id.
id – If specified, search for elements only inside the element with the specified id.

find_elements(method, target, id=None)¶

Returns a list of all HTMLElement instances that match the specified method and target in the current context.

An HTMLElement instance may be used to call other methods on the element, such as click(). If no element is immediately found, the attempt to locate an element will be repeated for up to the amount of time set by marionette_driver.timeout.Timeouts.implicit.

Parameters

method – The method to use to locate the elements; one of: “id”, “name”, “class name”, “tag name”, “css selector”, “link text”, “partial link text” and “xpath”. Note that the “name”, “link text” and “partial link test” methods are not supported in the chrome DOM.
target – The target of the search. For example, if method = “tag”, target might equal “div”. If method = “id”, target would be an element id.
id – If specified, search for elements only inside the element with the specified id.

navigate(url)¶

Navigate to given url.

Navigates the current top-level browsing context’s content frame to the given URL and waits for the document to load or the session’s page timeout duration to elapse before returning.

The command will return with a failure if there is an error loading the document or the URL is blocked. This can occur if it fails to reach the host, the URL is malformed, the page is restricted (about:* pages), or if there is a certificate issue to name some examples.

The document is considered successfully loaded when the DOMContentLoaded event on the frame element associated with the window triggers and document.readyState is “complete”.

In chrome context it will change the current window’s location to the supplied URL and wait until document.readyState equals “complete” or the page timeout duration has elapsed.

Parameters: url – The URL to navigate to.

This will terminate the currently running instance, and spawn a new instance with the same profile and then reuse the session id when creating a session again.

Parameters

clean – If False the same profile will be used after the restart. Note that the in app initiated restart always maintains the same profile.
in_app – If True, marionette will cause a restart from within the browser. Otherwise the browser will be restarted immediately by killing the process.
callback – If provided and in_app is True, the callback will be used to trigger the restart.

save_screenshot(fh, element=None, full=True, scroll=True)¶

Takes a screenhot of a web element or the current frame and saves it in the filehandle.

It is a wrapper around screenshot() :param fh: The filehandle to save the screenshot at.

The rest of the parameters are defined like in screenshot()

screenshot(element=None, format='base64', full=True, scroll=True)¶

Takes a screenshot of a web element or the current frame.

The screen capture is returned as a lossless PNG image encoded as a base 64 string by default. If the element argument is defined the capture area will be limited to the bounding box of that element. Otherwise, the capture area will be the bounding box of the current frame.

Parameters

element – The element to take a screenshot of. If None, will take a screenshot of the current frame.
format – if “base64” (the default), returns the screenshot as a base64-string. If “binary”, the data is decoded and returned as raw binary. If “hash”, the data is hashed using the SHA-256 algorithm and the result is returned as a hex digest.
full – If True (the default), the capture area will be the complete frame. Else only the viewport is captured. Only applies when element is None.

property now¶

sleep(duration)¶

class marionette_driver.wait.Wait(marionette, timeout=None, interval=None, ignored_exceptions=None, clock=None)¶

Bases: object

An explicit conditional utility class for waiting until a condition evaluates to true or not null.

This will repeatedly evaluate a condition in anticipation for a truthy return value, or its timeout to expire, or its waiting predicate to become true.

A Wait instance defines the maximum amount of time to wait for a condition, as well as the frequency with which to check the condition. Furthermore, the user may configure the wait to ignore specific types of exceptions whilst waiting, such as errors.NoSuchElementException when searching for an element on the page.

until(condition, is_true=None, message='')¶

Repeatedly runs condition until its return value evaluates to true, or its timeout expires or the predicate evaluates to true.

This will poll at the given interval until the given timeout is reached, or the predicate or conditions returns true. A condition that returns null or does not evaluate to true will fully elapse its timeout before raising an errors.TimeoutException.

If an exception is raised in the condition function and it’s not ignored, this function will raise immediately. If the exception is ignored, it will continue polling for the condition until it returns successfully or a TimeoutException is raised.

Parameters

condition – A callable function whose return value will be returned by this function if it evaluates to true.
is_true – An optional predicate that will terminate and return when it evaluates to False. It should be a function that will be passed clock and an end time. The default predicate will terminate a wait when the clock elapses the timeout.
message – An optional message to include in the exception’s message if this function times out.
