Expand description

Generic Appium client

This client represents an Appium client that will connect to an Appium server and send command to said server.

Depending on chosen capabilities (AppiumCapability), the client will have different traits. Which means - different available features.

Check out AndroidClient and IOSClient in docs to see their features (available commands).

Note: Client automatically ends Appium session on drop (end of lifetime). This is the only way to end session.

Methods from Deref<Target = Client>§

pub async fn issue_cmd( &self, cmd: impl WebDriverCompatibleCommand + Send + 'static ) -> Result<Value, CmdError>

Issue the specified [WebDriverCompatibleCommand] to the WebDriver instance.

pub async fn session_id(&self) -> Result<Option<String>, CmdError>

Get the unique session ID assigned by the WebDriver server to this client.

pub async fn set_ua<S>(&self, ua: S) -> Result<(), CmdError>where S: Into<String>,

Set the User Agent string to use for all subsequent requests.

pub async fn get_ua(&self) -> Result<Option<String>, CmdError>

Get the current User Agent string.

pub async fn persist(&self) -> Result<(), CmdError>

Mark this client’s session as persistent.

After all instances of a Client have been dropped, we normally shut down the WebDriver session, which also closes the associated browser window or tab. By calling this method, the shutdown command will not be sent to this client’s session, meaning its window or tab will remain open.

Note that an explicit call to [Client::close] will still terminate the session.

This function is safe to call multiple times.

pub async fn status(&self) -> Result<WebDriverStatus, CmdError>

Get the WebDriver status.

See 8.3 Status of the WebDriver standard.

pub async fn get_timeouts(&self) -> Result<TimeoutConfiguration, CmdError>

Get the timeouts for the current session.

See 8.4 Get Timeouts of the WebDriver standard.

pub async fn update_timeouts( &self, timeouts: TimeoutConfiguration ) -> Result<(), CmdError>

Set the timeouts for the current session.

See 8.5 Set Timeouts of the WebDriver standard.

pub async fn goto(&self, url: &str) -> Result<(), CmdError>

Navigate directly to the given URL.

See 9.1 Navigate To of the WebDriver standard.

pub async fn current_url(&self) -> Result<Url, CmdError>

Retrieve the currently active URL for this session.

See 9.2 Get Current URL of the WebDriver standard.

pub async fn back(&self) -> Result<(), CmdError>

Go back to the previous page.

See 9.3 Back of the WebDriver standard.

pub async fn forward(&self) -> Result<(), CmdError>

Go forward to the next page.

See 9.4 Forward of the WebDriver standard.

pub async fn refresh(&self) -> Result<(), CmdError>

Refresh the current previous page.

See 9.5 Refresh of the WebDriver standard.

pub async fn title(&self) -> Result<String, CmdError>

Get the current page title.

See 9.6 Get Title of the WebDriver standard.

pub async fn window(&self) -> Result<WindowHandle, CmdError>

Gets the current window handle.

See 10.1 Get Window Handle of the WebDriver standard.

pub async fn close_window(&self) -> Result<(), CmdError>

Closes the current window.

Will close the session if no other windows exist.

Closing a window will not switch the client to one of the remaining windows. The switching must be done by calling switch_to_window using a still live window after the current window has been closed.

See 10.2 Close Window of the WebDriver standard.

pub async fn switch_to_window( &self, window: WindowHandle ) -> Result<(), CmdError>

Switches to the chosen window.

See 10.3 Switch To Window of the WebDriver standard.

pub async fn windows(&self) -> Result<Vec<WindowHandle>, CmdError>

Gets a list of all active windows (and tabs)

See 10.4 Get Window Handles of the WebDriver standard.

pub async fn new_window( &self, as_tab: bool ) -> Result<NewWindowResponse, CmdError>

Creates a new window. If as_tab is true, then a tab will be created instead.

Windows are treated the same as tabs by the WebDriver protocol. The functions new_window, switch_to_window, close_window, window and windows all operate on both tabs and windows.

This operation is only in the editor’s draft of the next iteration of the WebDriver protocol, and may thus not be supported by all WebDriver implementations. For example, if you’re using geckodriver, you will need geckodriver > 0.24 and firefox > 66 to use this feature.

See 11.5 New Window of the editor’s draft standard.

pub async fn enter_frame(&self, index: Option<u16>) -> Result<(), CmdError>

Switches to the frame specified at the index.

See 10.5 Switch To Frame of the WebDriver standard.

pub async fn enter_parent_frame(&self) -> Result<(), CmdError>

Switches to the parent of the frame the client is currently contained within.

See 10.6 Switch To Parent Frame of the WebDriver standard.

pub async fn set_window_rect( &self, x: u32, y: u32, width: u32, height: u32 ) -> Result<(), CmdError>

Sets the x, y, width, and height properties of the current window.

See 10.7.2 Set Window Rect of the WebDriver standard.

pub async fn get_window_rect(&self) -> Result<(u64, u64, u64, u64), CmdError>

Gets the x, y, width, and height properties of the current window.

See 10.7.2 Set Window Rect of the WebDriver standard.

pub async fn get_window_position(&self) -> Result<(u64, u64), CmdError>

Gets the x and y top-left coordinate of the current window.

See 10.7.1 Get Window Rect of the WebDriver standard.

Maximize the current window.

See 10.7.3 Maximize Window of the WebDriver standard.

pub async fn minimize_window(&self) -> Result<(), CmdError>

Minimize the current window.

See 10.7.4 Minimize Window of the WebDriver standard.

pub async fn fullscreen_window(&self) -> Result<(), CmdError>

Make the current window fullscreen.

See 10.7.5 Fullscreen Window of the WebDriver standard.

pub async fn find(&self, search: Locator<'_>) -> Result<Element, CmdError>

Find an element on the page that matches the given [Locator].

See 12.2 Find Element of the WebDriver standard.

pub async fn find_all( &self, search: Locator<'_> ) -> Result<Vec<Element>, CmdError>

Find all elements on the page that match the given [Locator].

See 12.3 Find Elements of the WebDriver standard.

pub async fn active_element(&self) -> Result<Element, CmdError>

Get the active element for this session.

The “active” element is the Element within the DOM that currently has focus. This will often be an <input> or <textarea> element that currently has the text selection, or another input element such as a checkbox or radio button. Which elements are focusable depends on the platform and browser configuration.

If no element has focus, the result may be the page body or a NoSuchElement error.

See 12.6 Get Active Element of the WebDriver standard.

pub async fn form(&self, search: Locator<'_>) -> Result<Form, CmdError>

Locate a form on the page.

Through the returned Form, HTML forms can be filled out and submitted.

pub async fn source(&self) -> Result<String, CmdError>

Get the HTML source for the current page.

See 15.1 Get Page Source of the WebDriver standard.

pub async fn execute( &self, script: &str, args: Vec<Value> ) -> Result<Value, CmdError>

Execute the given JavaScript script in the current browser session.

args is available to the script inside the arguments array. Since Element implements Serialize, you can also provide serialized Elements as arguments, and they will correctly deserialize to DOM elements on the other side.

To retrieve the value of a variable, return has to be used in the JavaScript code.

See 15.2.1 Execute Script of the WebDriver standard.

pub async fn execute_async( &self, script: &str, args: Vec<Value> ) -> Result<Value, CmdError>

Execute the given async JavaScript script in the current browser session.

The provided JavaScript has access to args through the JavaScript variable arguments. The arguments array also holds an additional element at the end that provides a completion callback for the asynchronous code.

Since Element implements Serialize, you can also provide serialized Elements as arguments, and they will correctly deserialize to DOM elements on the other side.

Examples

Call a web API from the browser and retrieve the value asynchronously

const JS: &'static str = r#"
    const [date, callback] = arguments;

    fetch(`http://weather.api/${date}/hourly`)
    // whenever the HTTP Request completes,
    // send the value back to the Rust context
    .then(data => {
        callback(data.json())
    })
"#;

let weather = client.execute_async(JS, vec![date]).await?;

See 15.2.2 Execute Async Script of the WebDriver standard.

pub async fn perform_actions( &self, actions: impl Into<Actions> ) -> Result<(), CmdError>

Create a new Actions chain.

let mouse_actions = MouseActions::new("mouse")
    .then(PointerAction::Down {
        button: MOUSE_BUTTON_LEFT,
    })
    .then(PointerAction::MoveBy {
        duration: Some(Duration::from_secs(2)),
        x: 100,
        y: 0,
    })
    .then(PointerAction::Up {
        button: MOUSE_BUTTON_LEFT,
    });
client.perform_actions(mouse_actions).await?;

See the documentation for [Actions] for more information. Perform the specified input actions.

See 17.5 Perform Actions of the WebDriver standard.

pub async fn release_actions(&self) -> Result<(), CmdError>

Release all input actions.

See 17.6 Release Actions of the WebDriver standard.

pub async fn dismiss_alert(&self) -> Result<(), CmdError>

Dismiss the active alert, if there is one.

See 18.1 Dismiss Alert of the WebDriver standard.

pub async fn accept_alert(&self) -> Result<(), CmdError>

Accept the active alert, if there is one.

See 18.2 Accept Alert of the WebDriver standard.

pub async fn get_alert_text(&self) -> Result<String, CmdError>

Get the text of the active alert, if there is one.

See 18.3 Get Alert Text of the WebDriver standard.

pub async fn send_alert_text(&self, text: &str) -> Result<(), CmdError>

Send the specified text to the active alert, if there is one.

pub async fn screenshot(&self) -> Result<Vec<u8>, CmdError>

Get a PNG-encoded screenshot of the current page.

See 19.1 Take Screenshot of the WebDriver standard.

pub async fn wait_for<F, FF>(&self, is_ready: F) -> Result<(), CmdError>where F: FnMut(&Client) -> FF, FF: Future<Output = Result<bool, CmdError>>,

👎Deprecated since 0.17.5: This method might block forever. Please use client.wait().on(…) instead. You can still wait forever using: client.wait().forever().on(…)

Wait for the given function to return true before proceeding.

This can be useful to wait for something to appear on the page before interacting with it. While this currently just spins and yields, it may be more efficient than this in the future. In particular, in time, it may only run is_ready again when an event occurs on the page.

pub async fn wait_for_find( &self, search: Locator<'_> ) -> Result<Element, CmdError>

👎Deprecated since 0.17.5: This method might block forever. Please use client.wait().on(locator) instead. You can still wait forever using: client.wait().forever().on(locator)

Wait for the given element to be present on the page.

This can be useful to wait for something to appear on the page before interacting with it. While this currently just spins and yields, it may be more efficient than this in the future. In particular, in time, it may only run is_ready again when an event occurs on the page.

pub async fn wait_for_navigation( &self, current: Option<Url> ) -> Result<(), CmdError>

👎Deprecated since 0.17.5: This method might block forever and has a chance of randomly blocking. Please use client.wait().on(url) instead, to check if you navigated successfully to the new URL.

Wait for the page to navigate to a new URL before proceeding.

If the current URL is not provided, self.current_url() will be used. Note however that this introduces a race condition: the browser could finish navigating before we call current_url(), which would lead to an eternal wait.

pub async fn raw_client_for( &self, method: Method, url: &str ) -> Result<Response<Body>, CmdError>

Issue an HTTP request to the given url with all the same cookies as the current session.

Calling this method is equivalent to calling with_raw_client_for with an empty closure.

pub async fn with_raw_client_for<F>( &self, method: Method, url: &str, before: F ) -> Result<Response<Body>, CmdError>where F: FnOnce(Builder) -> Request<Body>,

Build and issue an HTTP request to the given url with all the same cookies as the current session.

Before the HTTP request is issued, the given before closure will be called with a handle to the Request about to be sent.

pub fn wait(&self) -> Wait<'_>

Starting building a new wait operation. This can be used to wait for a certain condition, by periodically checking the state and optionally returning a value:

// -- snip wrapper code --
let button = client.wait().for_element(Locator::Css(
    r#"a.button-download[href="/learn/get-started"]"#,
)).await?;
// -- snip wrapper code --
