Category: Element interaction
See: https://www.w3.org/TR/webdriver1/#dfn-element-clear.
The Element Click command scrolls into view the element if it is not already pointer-interactable, and clicks its in-view center point.
If the element’s center point is obscured by another element, an element click intercepted error is returned. If the element is outside the viewport, an element not interactable error is returned.

See: https://www.w3.org/TR/webdriver1/#take-element-screenshot .
The Element Send Keys command scrolls into view the form control element and then sends the provided keys to the element. In case the element is not keyboard-interactable, an element not interactable error is returned.
KEYS should be a string or a list of characters or control character keywords.
For example:
(element-send-keys el (list :control #t))
See KEY and KEYS functions.
Category: Element interaction
See: https://www.w3.org/TR/webdriver1/#element-send-keys .

The Get Element Text command intends to return an element’s text “as rendered”. An element’s rendered text is also used for locating a elements by their link text and partial link text.
Category: Elements
See: https://www.w3.org/TR/webdriver1/#get-element-text .
Inject a snippet of JavaScript into the page for execution in the context of the currently selected frame. The executed script is assumed to be synchronous and the result of evaluating the script is returned to the client.
The script argument defines the script to execute in the form of a function body. The value returned by that function will be returned to the client. The function will be invoked with the provided args array and the values may be accessed via the arguments object in the order specified.
Arguments may be any JSON-primitive, array, or JSON object. JSON objects that define a WebElement reference will be converted to the corresponding DOM element. Likewise, any WebElements in the script result will be returned to the client as WebElement JSON objects.
Category: Document handling
See: https://www.w3.org/TR/webdriver1/#executing-script .
Retrieve the cookie with name COOKIE-NAME.
Category: Cookies
See: https://www.w3.org/TR/webdriver1/#get-named-cookie
Find element by SELECTOR. Returns NIL if the element is not found.
The Find Element command is used to find an element in the current browsing context that can be used as the web element context for future element-centric commands.
For example, consider this pseudo code which retrieves an element with the #toremove ID and uses this as the argument for a script it injects to remove it from the HTML document:
let body = session.find.css("#toremove");
session.execute("arguments[0].remove()", [body]);
The BY parameter represents the element location strategy.
It can be one of:
- :id : Finds element by id.
- :class-name : Finds element by class name.
- :css-selector : Returns element that matches css selector.
- :link-text : Returns element that matches <a> element text.
- :partial-link-text: Returns element that matches <a> element text partially.
- :tag-name: Returns element that matches tag name.
- :xpath: Returns element that matches the XPath expression.
If result is empty, a HANDLE-FIND-ERROR is signaled.

Merge two capabilities
Category: Capabilities
Click any mouse button (at the coordinates set by the last moveto command). Note that calling this command after calling buttondown and before calling button up (or any out-of-order interactions sequence) will yield undefined behaviour).
See: https://github.com/SeleniumHQ/selenium/wiki/JsonWireProtocol#sessionsessionidclick
Move the mouse by an offset of the specificed element. If no element is specified, the move is relative to the current mouse cursor. If an element is provided but no offset, the mouse will be moved to the center of the element. If the element is not visible, it will be scrolled into view.
See: https://github.com/SeleniumHQ/selenium/wiki/JsonWireProtocol#sessionsessionidmoveto
Create a new top-level browsing context.
Category: Contexts
See: https://w3c.github.io/webdriver/#new-window
Returns a string serialization of the DOM of the current browsing context active document.
Category: Navigation
See: https://www.w3.org/TR/webdriver1/#get-page-source
This command returns the document title of the current top-level browsing context, equivalent to calling document.title.
Category: Navigation
See: https://www.w3.org/TR/webdriver2/#get-title .
The Actions API provides a low-level interface for providing virtualised device input to the web browser.
Conceptually, the Actions commands divide time into a series of ticks. The local end sends a series of actions which correspond to the change in state, if any, of each input device during each tick. For example, pressing a key is represented by an action sequence consisting of a single key input device and two ticks, the first containing a keyDown action, and the second a keyUp action, whereas a pinch-zoom input is represented by an action sequence consisting of three ticks and two pointer input devices of type touch, each performing a sequence of actions pointerDown, followed by pointerMove, and then pointerUp.
Category: Actions
See: https://www.w3.org/TR/webdriver/#actions
Refresh the current page.
Category: Navigation
Screenshots are a mechanism for providing additional visual diagnostic information. They work by dumping a snapshot of the initial viewport’s framebuffer as a lossless PNG image. It is returned to the local end as a Base64 encoded string.
Category: Screen capture
See: https://www.w3.org/TR/webdriver2/#screen-capture .
Send a key to active element.
Send keys to active element.
Start an interactive session. Use this to interact with Selenium driver from a REPL.
Category: Session
See: MAKE-SESSION
Stop an interactive session.
Sometimes *SESSION* could be out of sync with Webdriver instance. In that case we may want to ignore errors when trying to delete the session. IGNORE-ERRORS argument controls that.
Category: Session
Change focus to another frame on the page. If the frame id is null, the server
should switch to the page’s default content.
In the context of a web browser, a frame is a part of a web page or browser window which displays content independent of its container, with the ability to load content independently.
Category: Contexts
See: https://www.w3.org/TR/webdriver1/#switch-to-frame
Switching window will select the current top-level browsing context used as the target for all subsequent commands. In a tabbed browser, this will typically make the tab containing the browsing context the selected tab.
WINDOW-HANDLE is the handle of the window obtained via GET-WINDOW-HANDLE.
See: https://www.w3.org/TR/webdriver1/#switch-to-window
Category: Contexts
