thirtyfour 0.37.0

Thirtyfour is a Selenium / WebDriver library for Rust, for automated website UI testing. Tested on Chrome and Firefox, but any webdriver-capable browser should work.
Documentation
//! Run as follows:
//!
//!     cargo run --example shadowroot
//!
//! Uses `WebDriver::managed` (default `manager` feature), which auto-downloads
//! the matching `chromedriver` for your installed Chrome and starts it locally.

    // Navigate to website containing example shadowroot.
    driver.goto("https://web.dev/shadowdom-v1/").await?;

    let elem = driver.query(By::Tag("iframe")).first().await?;
    elem.enter_frame().await?;

    // Get the element containing the shadow root node.
    let elem = driver.query(By::Tag("fancy-tabs")).first().await?;
    // Now get the shadow root node itself.
    let root = elem.get_shadow_root().await?;

    // Now we can search for elements nested below the shadow root node.
    let tabs = root.query(By::Id("tabsSlot")).first().await?;
    let name = tabs.prop("name").await?;
    assert!(name.is_some());
    assert_eq!(name.unwrap(), "title");

    // Always explicitly close the browser. This prevents the executor from being blocked
    driver.quit().await?;

    Ok(())
