1.新建项目

使用RustCover新建项目，目录如下：

Cargo.toml文件

[package]
name = "Demo"
version = "0.1.0"
edition = "2021"

[dependencies]
tokio = { version = "1", features = ["full"] }
thirtyfour = { version = "0.31.0", features = ["component"] }
scraper = "0.15.0"

2.编写代码

以百度网站为例

use std::time::Duration;
use thirtyfour::By;
use tokio;
use thirtyfour::prelude::{DesiredCapabilities, WebDriver, WebDriverResult};

#[tokio::test]
async fn navigate_to_url() -> WebDriverResult<()> {
    let capabilities = DesiredCapabilities::chrome();
    let driver = WebDriver::new("http://localhost:9515", capabilities)
        .await
        .expect("Failed to connect to localhost:9515!");
    driver.maximize_window().await?;
    driver.set_implicit_wait_timeout(std::time::Duration::from_secs(10)).await?;
    tokio::time::sleep(Duration::from_secs(3)).await;
    driver
        .goto("https://www.baidu.com")
        .await
        .expect("Couldn't navigate to the URL!");
    tokio::time::sleep(Duration::from_secs(2)).await;
    let search_input = driver.find(By::Id("kw")).await?;
    search_input.send_keys("Hello").await?;
    tokio::time::sleep(Duration::from_secs(2)).await;
    let search_button = driver.find(By::Id("su")).await?;
    search_button.click().await?;
    tokio::time::sleep(Duration::from_secs(2)).await;
    let page_title = driver.title()
        .await
        .expect("Page title not found");
    driver.quit().await?;
    assert_eq!(
        page_title,
        "Hello_百度搜索"
    );
    Ok(())
}

3.运行项目

在RustCover打开终端，输入命令：

chromedriver --port=9515

然后再新建终端，输入命令：

cargo test
