Chrome Devtools Protocol with BiDi API

These examples are currently implemented with CDP, but the same code should work when the functionality is re-implemented with WebDriver-BiDi.

Usage

A seguinte lista de APIs crescerá à medida que o projeto Selenium se prepara para suportar casos de uso do mundo real. Se houver funcionalidades adicionais que você gostaria de ver, por favor, levante uma solicitação de recurso.

As these examples are re-implemented with the WebDriver-Bidi protocol, they will be moved to the WebDriver Bidi pages.

Examples

Basic authentication

Alguns aplicativos fazem o uso da autenticação do navegador para proteger suas páginas. Com o Selenium, você pode automatizar a entrada de credenciais básicas de autenticação sempre que for necessário.

Alternate implementations can be found at CDP Endpoint Basic Authentication and CDP API Basic Authentication

Move Code

const {Builder} = require('selenium-webdriver');

(async function example() {
  try {
    let driver = await new Builder()
      .forBrowser('chrome')
      .build();

    const pageCdpConnection = await driver.createCDPConnection('page');
    await driver.register('username', 'password', pageCdpConnection);
    await driver.get('https://the-internet.herokuapp.com/basic_auth');
    await driver.quit();
  }catch (e){
    console.log(e)
  }
}())

Move Code

val uriPredicate = Predicate { uri: URI ->
        uri.host.contains("your-domain.com")
    }
(driver as HasAuthentication).register(uriPredicate, UsernameAndPassword.of("admin", "password"))
driver.get("https://your-domain.com/login")

Pin scripts

This can be especially useful when executing on a remote server. For example, whenever you check the visibility of an element, or whenever you use the classic get attribute method, Selenium is sending the contents of a js file to the script execution endpoint. These files are each about 50kB, which adds up.

Mutation observation

Mutation Observation(Observação de Mutação) é a capacidade de capturar eventos via WebDriver BiDi quando há mutações DOM em um elemento específico no DOM.

Move Code

const {Builder, until} = require('selenium-webdriver');
const assert = require("assert");

(async function example() {
  try {
    let driver = await new Builder()
      .forBrowser('chrome')
      .build();

    const cdpConnection = await driver.createCDPConnection('page');
    await driver.logMutationEvents(cdpConnection, event => {
      assert.deepStrictEqual(event['attribute_name'], 'style');
      assert.deepStrictEqual(event['current_value'], "");
      assert.deepStrictEqual(event['old_value'], "display:none;");
    });

    await driver.get('dynamic.html');
    await driver.findElement({id: 'reveal'}).click();
    let revealed = driver.findElement({id: 'revealed'});
    await driver.wait(until.elementIsVisible(revealed), 5000);
    await driver.quit();
  }catch (e){
    console.log(e)
  }
}())

Console logs and errors

Vigie os eventos console.log e registre os callbacks(retornos de chamada) para processar o evento.

CDP API Console logs and WebDriver BiDi Console logs

Use the WebDriver BiDi Console logs implementation. HasLogEvents will likely end up deprecated because it does not implement Closeable.

Move Code

const {Builder} = require('selenium-webdriver');
(async () => {
  try {
    let driver = new Builder()
      .forBrowser('chrome')
      .build();

    const cdpConnection = await driver.createCDPConnection('page');
    await driver.onLogEvent(cdpConnection, function (event) {
      console.log(event['args'][0]['value']);
    });
    await driver.executeScript('console.log("here")');
    await driver.quit();
  }catch (e){
    console.log(e);
  }
})()

Move Code

fun kotlinConsoleLogExample() {
    val driver = ChromeDriver()
    val devTools = driver.devTools
    devTools.createSession()

    val logConsole = { c: ConsoleEvent -> print("Console log message is: " + c.messages)}
    devTools.domains.events().addConsoleListener(logConsole)

    driver.get("https://www.google.com")

    val executor = driver as JavascriptExecutor
    executor.executeScript("console.log('Hello World')")

    val input = driver.findElement(By.name("q"))
    input.sendKeys("Selenium 4")
    input.sendKeys(Keys.RETURN)
    driver.quit()
}

JavaScript exceptions

Vigie as exceções JS e registre callbacks(retornos de chamada) para processar os detalhes da exceção.

Use the WebDriver BiDi JavaScript exceptions implementation

await driver.onIntercept(connection, httpResponse, async function () {
  let body = await driver.getPageSource()
  assert.strictEqual(body.includes("sausages"), true, `Body contains: ${body}`)

driver.get(url)

val driver = ChromeDriver()
