1 - Começando

Selenium suporta automação de todos os principais navegadores do mercado por meio do uso do WebDriver. WebDriver é uma API e protocolo que define uma interface de linguagem neutra para controlar o comportamento dos navegadores da web. Cada navegador é apoiado por uma implementação WebDriver específica, chamada de driver. O driver é o componente responsável por delegar ao navegador, e lida com a comunicação de e para o Selenium e o navegador.

Essa separação é parte de um esforço consciente para que os fornecedores de navegadores assumam a responsabilidade pela implementação de seus navegadores. Selenium faz uso desses drivers de terceiros sempre que possível, mas também fornece seus próprios drivers mantidos pelo projeto para os casos em que isso não é uma realidade.

A estrutura do Selenium une todas essas peças por meio de uma interface voltada para o usuário que permite aos diferentes back-ends de navegador serem usados de forma transparente, permitindo a automação entre navegadores e plataformas cruzadas.

Selenium setup is quite different from the setup of other commercial tools. Before you can start writing Selenium code, you have to install the language bindings libraries for your language of choice, the browser you want to use, and the driver for that browser.

Follow the links below to get up and going with Selenium WebDriver.

If you wish to start with a low-code/record and playback tool, please check Selenium IDE

Once you get things working, if you want to scale up your tests, check out the Selenium Grid.

1.1 - Instalando bibliotecas do Selenium

Primeiro você precisa instalar as bibliotecas Selenium para seu projeto de automação. O processo de instalação de bibliotecas depende da linguagem que você escolher usar.

Requisitos por linguagem

• Java
• Python
• CSharp
• Ruby
• JavaScript
• Kotlin

    <dependencies>
        <dependency>
            <groupId>org.seleniumhq.selenium</groupId>
            <artifactId>selenium-java</artifactId>

    testImplementation 'org.seleniumhq.selenium:selenium-java:4.9.1'
    testImplementation 'org.seleniumhq.selenium:selenium-grid:4.9.1'

pip install selenium

python setup.py install

selenium==4.9.1

Install-Package Selenium.WebDriver

dotnet add package Selenium.WebDriver

      <PackageReference Include="Selenium.WebDriver" Version="4.9.0" />

<configuration>
  <packageSources>
    <add key="nuget.org" value="https://api.nuget.org/v3/index.json" protocolVersion="3" />
    <add key="nuget.org" value="https://www.nuget.org/api/v2/" />   
  </packageSources>
...

gem install selenium-webdriver

gem 'selenium-webdriver', '= 4.9.1'

npm install selenium-webdriver

        "selenium-webdriver": "^4.9.2"

Próximo passo

Programando o seu primeiro script Selenium

1.2 - Programe o seu primeiro script Selenium

Assim que você tiver o Selenium instalado, você estará pronto para programar códigos Selenium.

Oito Componentes Básicos

Tudo que o Selenium faz é enviar comandos ao navegador de internet para fazer algo ou solicitar informações dele. A maior parte do que você irá fazer com o Selenium é uma combinação desses comandos básicos.

Click on the link to “View full example on GitHub” to see the code in context.

1. Iniciando uma sessão

Para ter mais detalhes sobre como iniciar uma sessão, leia nossa documentação em driver sessions

• Java
• Python
• CSharp
• Ruby
• JavaScript
• Kotlin

        WebDriver driver = new ChromeDriver();

driver = webdriver.Chrome()

        IWebDriver driver = new ChromeDriver();

driver = Selenium::WebDriver.for :chrome

        driver = ChromeDriver()

2. Agindo no navegador de internet

Nesse exemplo estamos navegando para uma página web.

• Java
• Python
• CSharp
• Ruby
• JavaScript
• Kotlin

        driver.get("https://www.selenium.dev/selenium/web/web-form.html");

driver.get("https://www.selenium.dev/selenium/web/web-form.html")

        driver.Navigate().GoToUrl("https://www.selenium.dev/selenium/web/web-form.html");

driver.get('https://www.selenium.dev/selenium/web/web-form.html')

    before(async function () {

        driver.get("https://www.selenium.dev/selenium/web/web-form.html")

3. Solicitando informação do navegador de internet

Existem diversos tipos de informação sobre o navegador de internet que você pode solicitar, incluindo window handles, tamanho / posição do navegador, cookies, alertas e etc.

• Java
• Python
• CSharp
• Ruby
• JavaScript
• Kotlin

        driver.getTitle();

title = driver.title

        var title = driver.Title;

driver.title

    });

        val title = driver.title

4. Estabelecendo uma Estratégia de Espera

Sincronizar o código ao estado atual do navegador é um dos maiores desafios quando se trabalha com o Selenium, fazer isso de maneira bem feita é um tópico avançado.

Essencialmente, você quer ter certeza absoluta de que o elemento está na página antes de tentar localizá-lo e o elemento está em um estado interativo antes de você tentar interagir com ele.

Uma espera implícita raramente é a melhor solução, mas é a mais fácil de demonstrar aqui, então vamos usá-la como um substituto.

Leia mais sobre Estratégias de espera.

• Java
• Python
• CSharp
• Ruby
• JavaScript
• Kotlin

        driver.manage().timeouts().implicitlyWait(Duration.ofMillis(500));

driver.implicitly_wait(0.5)

        driver.Manage().Timeouts().ImplicitWait = TimeSpan.FromMilliseconds(500);

driver.manage.timeouts.implicit_wait = 500

        driver.manage().timeouts().implicitlyWait(Duration.ofMillis(500))

5. Encontrando um elemento

A maioria dos comandos na maior parte das sessões do Selenium são relacionados a elementos e você não pode interagir com um sem o primeiro encontrando um elemento

• Java
• Python
• CSharp
• Ruby
• JavaScript
• Kotlin

        WebElement textBox = driver.findElement(By.name("my-text"));
        WebElement submitButton = driver.findElement(By.cssSelector("button"));

text_box = driver.find_element(by=By.NAME, value="my-text")
submit_button = driver.find_element(by=By.CSS_SELECTOR, value="button")

        var textBox = driver.FindElement(By.Name("my-text"));
        var submitButton = driver.FindElement(By.TagName("button"));

text_box = driver.find_element(name: 'my-text')
submit_button = driver.find_element(tag_name: 'button')

      await driver.get('https://www.selenium.dev/selenium/web/web-form.html');

        var textBox = driver.findElement(By.name("my-text"))
        val submitButton = driver.findElement(By.cssSelector("button"))

6. Agindo no elemento

Há apenas um punhado de ações a serem executadas em um elemento, mas você irá usá-las com frequência.

• Java
• Python
• CSharp
• Ruby
• JavaScript
• Kotlin

        textBox.sendKeys("Selenium");
        submitButton.click();

text_box.send_keys("Selenium")
submit_button.click()

        textBox.SendKeys("Selenium");
        submitButton.Click();

text_box.send_keys('Selenium')
submit_button.click

      assert.equal("Web form", title);

        textBox.sendKeys("Selenium")
        submitButton.click()

7. Solicitando informações do elemento

Elementos podem guardar muitas informações que podem ser solicitadas.

• Java
• Python
• CSharp
• Ruby
• JavaScript
• Kotlin

        message.getText();

text = message.text

        var value = message.Text;

message.text

      let textBox = await driver.findElement(By.name('my-text'));

        val value = message.getText()

8. Encerrando a sessão

Isso encerra o processo do driver, que por padrão também fecha o navegador. Nenhum outro comando pode ser enviado para esta instância do driver.

See Quitting Sessions.

• Java
• Python
• CSharp
• Ruby
• JavaScript
• Kotlin

        driver.quit();

driver.quit()

        driver.Quit();

driver.quit

        driver.quit()

Running Selenium File

• Java
• Python
• CSharp
• Ruby
• JavaScript
• Kotlin

mvn exec:java -D"exec.mainClass"="dev.selenium.getting_started.FirstScript" -D"exec.classpathScope"=test

python first_script.py

ruby example_script.rb

node example_script.spec.js

Próximos Passos

Most Selenium users execute many sessions and need to organize them to minimize duplication and keep the code more maintainable. Read on to learn about how to put this code into context for your use case with Using Selenium.

1.3 - Organizando e executando o código Selenium

Se quiser executar mais do que um punhado de scripts pontuais, precisa de ser capaz de organizar e trabalhar com seu código. Esta página deve dar a você ideias de como fazer coisas produtivas com seu código Selenium.

Usos comuns

A maioria das pessoas usa o Selenium para executar testes automatizados para aplicações web, mas o Selenium suporta qualquer caso de uso de automação de navegador.

Tarefas Repetitivas

Talvez seja necessário fazer login em um site e baixar algo ou enviar um formulário. Você pode criar um script Selenium para ser executado com um serviço em horários pré-definidos.

Web Scrapping

Está a tentar recolher dados de um site que não tem uma API? O Selenium permitirá que você faça isso, mas certifique-se de estar familiarizado com os termos de serviço do site termos de serviço do site, pois alguns sites não permitem isso e outros até bloqueiam o Selenium.

Testes

Executar o Selenium para testes requer fazer asserções sobre as ações tomadas pelo Selenium. Então uma boa biblioteca de asserções é necessária. Características adicionais para prover estrutura para testes requerem o uso de [Test Runner] (#test-runners).

IDEs

Independentemente de como você usa o código do Selenium, não será muito eficaz escrevendo ou executando-o sem um bom ambiente de desenvolvimento integrado. Aqui estão algumas opções comuns…

• Eclipse
• IntelliJ IDEA
• PyCharm
• RubyMine
• Rider
• WebStorm
• VS Code

Executador de teste

Mesmo que não esteja a usar o Selenium para testes, se tiver casos de uso avançado, pode fazer sentido usar um executor de testes para organizar melhor seu código. Ser capaz de usar hooks antes/depois e executar coisas em grupos ou em paralelo pode ser muito útil.

Escolhendo

Há muitos executores de teste diferentes disponíveis.

Todos os exemplos de código nesta documentação podem ser encontrados em (ou estão sendo movidos para) nossos diretórios que usam test runners e são executados a cada lançamento para garantir que todo o código esteja correto e atualizado. Aqui está uma lista de executores de teste com links. O primeiro item é o que é usado por este repositório e o que que será usado para todos os exemplos nesta página.

• Java
• Python
• CSharp
• Ruby
• JavaScript
• Kotlin

Instalando

Isto é muito semelhante ao que foi requerido em Install a Selenium Library. Este código está apenas a mostrar exemplos do que está a ser usado no nosso projeto de Exemplos de Documentação.

• Java
• Python
• CSharp
• Ruby
• JavaScript
• Kotlin

Afirmar

• Java
• Python
• CSharp
• Ruby
• JavaScript
• Kotlin

        WebElement message = driver.findElement(By.id("message"));

    driver.get("https://www.selenium.dev/selenium/web/web-form.html")

            var title = driver.Title;
            Assert.AreEqual("Web form", title);

    driver.manage.timeouts.implicit_wait = 500

      let title = await driver.getTitle();
      assert.equal("Web form", title);

Configuarar e Desconfigurar

• Java
• Python
• CSharp
• Ruby
• JavaScript

    driver = Selenium::WebDriver.for :chrome

    driver.get('https://www.selenium.dev/selenium/web/web-form.html')

  config.after { @driver&.quit }

    before(async function () {
      driver = await new Builder().forBrowser('chrome').build();
    });

    after(async () => await driver.quit());

2 - Driver Sessions

Starting and stopping a session is for opening and closing a browser.

Creating Sessions

Creating a new session corresponds with the W3C command for New session

The session is created automatically by initializing a new Driver class object.

Each language allows a session to be created with arguments from one of these classes (or equivalent):

• Options to describe the kind of session you want; default values are used for local, but this is required for remote
• Some form of Http Client Configuration (the implementation varies between languages)
• Listeners

Local Driver

The primary unique argument for starting a local driver includes information about starting the required driver service on the local machine.

• Service object applies only to local drivers and provides information about the browser driver

• Java
• Python
• CSharp
• Ruby
• JavaScript
• Kotlin

    WebDriver driver = new ChromeDriver(chromeOptions);

    options.page_load_strategy = 'normal'

            driver = new ChromeDriver(options);

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

    let driver = new Builder()
        .forBrowser(Browser.CHROME)
        .setChromeOptions(options)
        .setChromeService(service)
        .build();

Remote Driver

The primary unique argument for starting a remote driver includes information about where to execute the code. Read the details in the Remote Driver Section

Quitting Sessions

Quitting a session corresponds to W3C command for Deleting a Session.

Important note: the quit method is different from the close method, and it is recommended to always use quit to end the session

• Java
• Python
• CSharp
• Ruby
• JavaScript
• Kotlin

        driver.quit();

        driver.Quit();

  end

        driver.quit()

2.1 - Opções do navegador

No Selenium 3, os recursos foram definidos em uma sessão usando classes de recursos desejados. A partir do Selenium 4, você deve usar as classes de opções do navegador. Para sessões remotas de driver, uma instância de opções do navegador é necessária, pois determina qual navegador será usado.

Essas opções são descritas na especificação w3c para Capabilities.

Cada navegador tem custom options que podem ser definidas além das definidas na especificação.

browserName

Esta capacidade é usada para definir o browserName para uma determinada sessão. Se o navegador especificado não estiver instalado no extremidade remota, a criação da sessão falhará.

• Java
• Python
• CSharp
• Ruby
• JavaScript
• Kotlin

	ChromeOptions chromeOptions = new ChromeOptions();
	String name = chromeOptions.getBrowserName();

    options.set_window_rect = True # Full support in Firefox
    driver = webdriver.Firefox(options=options)

      options.page_load_strategy = :normal

browserVersion

Esta capacidade é opcional, é usada para defina a versão do navegador disponível na extremidade remota. Por exemplo, se solicitar o Chrome versão 75 em um sistema que tiver apenas 80 instalados, a criação da sessão falhará.

• Java
• Python
• CSharp
• Ruby
• JavaScript
• Kotlin

	ChromeOptions chromeOptions = new ChromeOptions();
	String version = "latest";
	chromeOptions.setBrowserVersion(version);

    options = webdriver.ChromeOptions()
    options.strict_file_interactability = True
    driver = webdriver.Chrome(options=options)

pageLoadStrategy

Três tipos de estratégias de carregamento de página estão disponíveis.

A estratégia de carregamento da página consulta o document.readyState conforme descrito na tabela abaixo:

A propriedade document.readyState de um documento descreve o estado de carregamento do documento atual.

Ao navegar para uma nova página via URL, por padrão, o WebDriver irá adiar a conclusão de uma navegação (por exemplo, driver.navigate().get()) até que o estado pronto do documento seja concluído. isso não significa necessariamente que a página terminou de carregar, especialmente para sites como Single Page Applications que usam JavaScript para carregar conteúdo dinamicamente depois que o estado Pronto retorna completo. Observe também que esse comportamento não se aplica à navegação resultante de clicar em um elemento ou enviar um formulário.

Se uma página demorar muito para carregar como resultado do download de ativos (por exemplo, imagens, css, js) que não são importantes para a automação, você pode mudar do parâmetro padrão de normal para eager ou none para acelerar a sessão. Esse valor se aplica a toda a sessão, portanto, certifique-se que sua waiting strategy é suficiente para minimizar descamação.

normal (default)

WebDriver waits until the load event fire is returned.

• Java
• Python
• CSharp
• Ruby
• JavaScript
• Kotlin

      driver.quit();
    }
  }

    options.page_load_strategy = 'normal'
    driver = webdriver.Chrome(options=options)

using OpenQA.Selenium;
using OpenQA.Selenium.Chrome;

namespace pageLoadStrategy {
  class pageLoadStrategy {
    public static void Main(string[] args) {
      var chromeOptions = new ChromeOptions();
      chromeOptions.PageLoadStrategy = PageLoadStrategy.Normal;
      IWebDriver driver = new ChromeDriver(chromeOptions);
      try {
        driver.Navigate().GoToUrl("https://example.com");
      } finally {
        driver.Quit();
      }
    }
  }
}

      options.page_load_strategy = :normal

    it('Navigate using normal page loading strategy', async function () {
      let driver = await env
        .builder()
        .setChromeOptions(options.setPageLoadStrategy('normal'))
        .build();

      await driver.get('https://www.google.com');

import org.openqa.selenium.PageLoadStrategy
import org.openqa.selenium.chrome.ChromeDriver
import org.openqa.selenium.chrome.ChromeOptions

fun main() {
  val chromeOptions = ChromeOptions()
  chromeOptions.setPageLoadStrategy(PageLoadStrategy.NORMAL)
  val driver = ChromeDriver(chromeOptions)
  try {
    driver.get("https://www.google.com")
  }
  finally {
    driver.quit()
  }
}

eager

WebDriver waits until DOMContentLoaded event fire is returned.

• Java
• Python
• CSharp
• Ruby
• JavaScript
• Kotlin

      driver.quit();
    }
  }

    options = webdriver.ChromeOptions()

    options.page_load_strategy = 'eager'

using OpenQA.Selenium;
using OpenQA.Selenium.Chrome;

namespace pageLoadStrategy {
  class pageLoadStrategy {
    public static void Main(string[] args) {
      var chromeOptions = new ChromeOptions();
      chromeOptions.PageLoadStrategy = PageLoadStrategy.Eager;
      IWebDriver driver = new ChromeDriver(chromeOptions);
      try {
        driver.Navigate().GoToUrl("https://example.com");
      } finally {
        driver.Quit();
      }
    }
  }
}

       options.page_load_strategy = :eager

    it('Navigate using eager page loading strategy', async function () {
      let driver = await env
        .builder()
        .setChromeOptions(options.setPageLoadStrategy('eager'))
        .build();

      await driver.get('https://www.google.com');

import org.openqa.selenium.PageLoadStrategy
import org.openqa.selenium.chrome.ChromeDriver

platformName

This identifies the operating system at the remote-end, fetching the platformName returns the OS name.

In cloud-based providers, setting platformName sets the OS at the remote-end.

• Java
• Python
• CSharp
• Ruby
• JavaScript
• Kotlin

acceptInsecureCerts

This capability checks whether an expired (or) invalid TLS Certificate is used while navigating during a session.

If the capability is set to false, an insecure certificate error will be returned as navigation encounters any domain certificate problems. If set to true, invalid certificate will be trusted by the browser.

All self-signed certificates will be trusted by this capability by default. Once set, acceptInsecureCerts capability will have an effect for the entire session.

• Java
• Python
• CSharp
• Ruby
• JavaScript
• Kotlin

}, { browsers: [Browser.CHROME, Browser.FIREFOX]});

timeouts

A WebDriver session is imposed with a certain session timeout interval, during which the user can control the behaviour of executing scripts or retrieving information from the browser.

Each session timeout is configured with combination of different timeouts as described below:

Script Timeout

Specifies when to interrupt an executing script in a current browsing context. The default timeout 30,000 is imposed when a new session is created by WebDriver.

• Java
• Python
• CSharp
• Ruby
• JavaScript
• Kotlin

    driver.get("http://www.google.com")
    driver.quit()

Page Load Timeout

Specifies the time interval in which web page needs to be loaded in a current browsing context. The default timeout 300,000 is imposed when a new session is created by WebDriver. If page load limits a given/default time frame, the script will be stopped by TimeoutException.

• Java
• Python
• CSharp
• Ruby
• JavaScript
• Kotlin

Implicit Wait Timeout

This specifies the time to wait for the implicit element location strategy when locating elements. The default timeout 0 is imposed when a new session is created by WebDriver.

• Java
• Python
• CSharp
• Ruby
• JavaScript
• Kotlin

unhandledPromptBehavior

Specifies the state of current session’s user prompt handler. Defaults to dismiss and notify state

User Prompt Handler

This defines what action must take when a user prompt encounters at the remote-end. This is defined by unhandledPromptBehavior capability and has the following states:

• dismiss
• accept
• dismiss and notify
• accept and notify
• ignore

• Java
• Python
• CSharp
• Ruby
• JavaScript
• Kotlin

setWindowRect

Indicates whether the remote end supports all of the resizing and repositioning commands.

• Java
• Python
• CSharp
• Ruby
• JavaScript
• Kotlin

strictFileInteractability

This new capability indicates if strict interactability checks should be applied to input type=file elements. As strict interactability checks are off by default, there is a change in behaviour when using Element Send Keys with hidden file upload controls.

• Java
• Python
• CSharp
• Ruby
• JavaScript
• Kotlin

proxy

A proxy server acts as an intermediary for requests between a client and a server. In simple, the traffic flows through the proxy server on its way to the address you requested and back.

A proxy server for automation scripts with Selenium could be helpful for:

• Capture network traffic
• Mock backend calls made by the website
• Access the required website under complex network topologies or strict corporate restrictions/policies.

If you are in a corporate environment, and a browser fails to connect to a URL, this is most likely because the environment needs a proxy to be accessed.

Selenium WebDriver provides a way to proxy settings:

2.3 - Driver Service Class

The Service classes are for managing the starting and stopping of drivers. They can not be used with a Remote WebDriver session.

Service classes allow you to specify information about the driver, like location and which port to use. They also let you specify what arguments get passed to the command line. Most of the useful arguments are related to logging.

Default Service instance

To start a driver with a default service instance:

• Java
• Python
• CSharp
• Ruby
• JavaScript
• Kotlin

import org.openqa.selenium.remote.service.DriverService;

from selenium.webdriver.chrome.service import Service as ChromeService

        [TestMethod]
        public void BasicService()

  end

Driver location

Note: If you are using Selenium 4.6 or greater, you shouldn’t need to set a driver location. If you can not update Selenium or have an advanced use case here is how to specify the driver location:

• Java
• Python
• CSharp
• Ruby
• JavaScript
• Kotlin

  @Test

    driver_path = os.getenv('CHROMEWEBDRIVER') + 'chromedriver'

        {

Driver port

If you want the driver to run on a specific port, you may specify it as follows:

• Java
• Python
• CSharp
• Ruby
• JavaScript
• Kotlin

  public void setDriverLocation() {

def test_driver_port():

        {

Logging

Logging functionality varies between browsers. Most browsers allow you to specify location and level of logs. Take a look at the respective browser page:

• Chrome
• Edge
• Firefox
• Internet Explorer
• Safari

2.4 - Remote WebDriver

Selenium lets you automate browsers on remote computers if there is a Selenium Grid running on them. The computer that executes the code is referred to as the client computer, and the computer with the browser and driver is referred to as the remote computer or sometimes as an end-node. To direct Selenium tests to the remote computer, you need to use a Remote WebDriver class and pass the URL including the port of the grid on that machine. Please see the grid documentation for all the various ways the grid can be configured.

Basic Example

The driver needs to know where to send commands to and which browser to start on the Remote computer. So an address and an options instance are both required.

• Java
• Python
• CSharp
• Ruby
• JavaScript
• Kotlin

    driver = new RemoteWebDriver(gridUrl, options);
  }

    assert "localhost" in driver.command_executor._url
    driver.quit()

            driver = new RemoteWebDriver(GridUrl, options);

    options = Selenium::WebDriver::Options.chrome
    driver = Selenium::WebDriver.for :remote, url: grid_url, options: options

Uploads

Uploading a file is more complicated for Remote WebDriver sessions because the file you want to upload is likely on the computer executing the code, but the driver on the remote computer is looking for the provided path on its local file system. The solution is to use a Local File Detector. When one is set, Selenium will bundle the file, and send it to the remote machine, so the driver can see the reference to it. Some bindings include a basic local file detector by default, and all of them allow for a custom file detector.

• Java
• Python
• CSharp
• Ruby
• JavaScript
• Kotlin

    WebElement fileInput = driver.findElement(By.cssSelector("input[type=file]"));
    fileInput.sendKeys(uploadFile.getAbsolutePath());
    driver.findElement(By.id("file-submit")).click();

    file_name_element = driver.find_element(By.ID, "uploaded-files")
    file_name = file_name_element.text

            IWebElement fileInput = driver.FindElement(By.CssSelector("input[type=file]"));
            fileInput.SendKeys(uploadFile);
            driver.FindElement(By.Id("file-submit")).Click();

    driver.file_detector = ->((filename, *)) { filename.include?('selenium') && filename }
    file_input = driver.find_element(css: 'input[type=file]')
    file_input.send_keys(upload_file)
    driver.find_element(id: 'file-submit').click

Downloads

Chrome, Edge and Firefox each allow you to set the location of the download directory. When you do this on a remote computer, though, the location is on the remote computer’s local file system. Selenium allows you to enable downloads to get these files onto the client computer.

Enable Downloads in the Grid

Regardless of the client, when starting the grid in node or standalone mode, you must add the flag:

--enable-managed-downloads true

Enable Downloads in the Client

The grid uses the se:downloadsEnabled capability to toggle whether to be responsible for managing the browser location. Each of the bindings have a method in the options class to set this.

• Java
• Python
• CSharp
• Ruby
• JavaScript
• Kotlin

    options.setEnableDownloads(true);
    driver = new RemoteWebDriver(gridUrl, options);

    driver.get('https://www.selenium.dev/selenium/web/downloads/download.html')
    driver.find_element(By.ID, "file-1").click()
    driver.find_element(By.ID, "file-2").click()

            {
                EnableDownloads = true
            };
            driver = new RemoteWebDriver(GridUrl, options);

            driver.Url = "https://selenium.dev/selenium/web/downloads/download.html";

    options = Selenium::WebDriver::Options.chrome(enable_downloads: true)
    driver = Selenium::WebDriver.for :remote, url: grid_url, options: options
