Overview

The ActionBuilder provides the user a way to set up and perform complex user interactions.

This class should not be instantiated directly, but is created by Selenium::WebDriver::DriverExtensions::HasInputDevices#action, which is available on Driver instances that support the user interaction API.

Examples:


driver.action.key_down(:shift).
              click(element).
              click(second_element).
              key_up(:shift).
              drag_and_drop(element, third_element).
              perform

Instance Method Details

#click(element = nil) ⇒ ActionBuilder

Clicks in the middle of the given element. Equivalent to:

driver.action.move_to(element).click

When no element is passed, the current mouse position will be clicked.

Examples:

Clicking on an element


el = driver.find_element(:id, "some_id")
driver.action.click(el).perform

Clicking at the current mouse position


driver.action.click.perform

Parameters:

Returns:

def click(element = nil)
  @actions << [:mouse, :click, [element]]
  self
end

#click_and_hold(element) ⇒ ActionBuilder

Clicks (without releasing) in the middle of the given element. This is equivalent to:

driver.action.move_to(element).click_and_hold

Examples:

Clicking and holding on some element


el = driver.find_element(:id, "some_id")
driver.action.click_and_hold(el).perform

  self
end

#context_click(element) ⇒ ActionBuilder

Performs a context-click at middle of the given element. First performs a move_to to the location of the element.

Examples:

Context-click at middle of given element


el = driver.find_element(:id, "some_id")
driver.action.context_click(el).perform

end

#double_click(element = nil) ⇒ ActionBuilder

Performs a double-click at middle of the given element. Equivalent to:

driver.action.move_to(element).double_click

Examples:

Double click an element

end

#drag_and_drop(source, target) ⇒ ActionBuilder

A convenience method that performs click-and-hold at the location of the source element, moves to the location of the target element, then releases the mouse.

Examples:

Drag and drop one element onto another


el1 = driver.find_element(:id, "some_id1")
el2 = driver.find_element(:id, "some_id2")
driver.action.drag_and_drop(el1, el2).perform

end

#drag_and_drop_by(source, right_by, down_by) ⇒ ActionBuilder

A convenience method that performs click-and-hold at the location of the source element, moves by a given offset, then releases the mouse.

Examples:

Drag and drop an element by offset


el = driver.find_element(:id, "some_id1")
driver.action.drag_and_drop_by(el, 100, 100).perform

  release

  self
end

#key_down(*args) ⇒ ActionBuilder

Performs a modifier key press. Does not release the modifier key - subsequent interactions may assume it’s kept pressed. Note that the modifier key is never released implicitly - either #key_up(key) or #send_keys(:null) must be called to release the modifier.

Equivalent to:

driver.action.click(element).send_keys(key)
# or
driver.action.click.send_keys(key)

Examples:

Press a key


driver.action.key_down(:control).perform

Press a key on an element


el = driver.find_element(:id, "some_id")
driver.action.key_down(el, :shift).perform

Parameters:

Returns:

Raises:

  • (ArgumentError) —

    if the given key is not a modifier

    @actions << [:mouse, :click, [args.shift]]
  end

  @actions << [:keyboard, :press, args]
  self
end

#key_up(*args) ⇒ ActionBuilder

Performs a modifier key release. Releasing a non-depressed modifier key will yield undefined behaviour.

Examples:

Release a key


driver.action.key_up(:shift).perform

Release a key from an element


el = driver.find_element(:id, "some_id")
driver.action.key_up(el, :alt).perform

Parameters:

Returns:

Raises:

  • (ArgumentError) —

    if the given key is not a modifier key

#move_by(right_by, down_by) ⇒ ActionBuilder

Moves the mouse from its current position (or 0,0) by the given offset. If the coordinates provided are outside the viewport (the mouse will end up outside the browser window) then the viewport is scrolled to match.

Examples:

Move the mouse to a certain offset from its current position


driver.action.move_by(100, 100).perform

Parameters:

  • right_by (Integer) —

    horizontal offset. A negative value means moving the mouse left.

  • down_by (Integer) —

    vertical offset. A negative value means moving the mouse up.

Returns:

Raises:

  • (MoveTargetOutOfBoundsError) —

    if the provided offset is outside the document’s boundaries.

  self
end

#move_to(element, right_by = nil, down_by = nil) ⇒ ActionBuilder

Moves the mouse to the middle of the given element. The element is scrolled into view and its location is calculated using getBoundingClientRect. Then the mouse is moved to optional offset coordinates from the element.

Note that when using offsets, both coordinates need to be passed.

Examples:

Scroll element into view and move the mouse to it


el = driver.find_element(:id, "some_id")
driver.action.move_to(el).perform

el = driver.find_element(:id, "some_id")
driver.action.move_to(el, 100, 100).perform

Parameters:

  • element (Selenium::WebDriver::Element) —

    to move to.

  • right_by (Integer) (defaults to: nil) —

    Optional offset from the top-left corner. A negative value means coordinates right from the element.

  • down_by (Integer) (defaults to: nil) —

    Optional offset from the top-left corner. A negative value means coordinates above the element.

Returns:

  end

  nil
end

#release(element = nil) ⇒ ActionBuilder

Releases the depressed left mouse button at the current mouse location.

Examples:

Releasing an element after clicking and holding it


el = driver.find_element(:id, "some_id")
driver.action.click_and_hold(el).release.perform

Returns:

def release(element = nil)
  @actions << [:mouse, :up, [element]]
  self
end

#send_keys(*args) ⇒ ActionBuilder

Sends keys to the active element. This differs from calling Element#send_keys(keys) on the active element in two ways:

  • The modifier keys included in this call are not released.

  • There is no attempt to re-focus the element - so send_keys(:tab) for switching elements should work.

Examples:

Send the text “help” to an element


el = driver.find_element(:id, "some_id")
driver.action.send_keys(el, "help").perform

Send the text “help” to the currently focused element


driver.action.send_keys("help").perform

Parameters:
