selenium - 我想用 Selenium 进行测试，但出现错误 Webdrivers :: BrowserNotFound

问题描述

我目前使用 Rails5、Rspec、Selenium 和 webdrivers gems 编写测试。
但是，我收到错误 Webdrivers :: BrowserNotFound 并且我无法运行它。

我认为这是由于 Selenium 没有找到 ChromeDriver。
但是，这个问题应该已经通过 webdrivers gem 解决了，但它似乎没有按预期工作。
详情会写在下面。

     1.1) Failure/Error: visit hoges_index_path

          Webdrivers::BrowserNotFound:
            Failed to find Chrome binary.

RSpec.feature 'HogeIndex', type: :system do
  before(:each) do
    visit hoges_index_path
  end
  scenario 'hoge' do
    expect(all('.hoge').count).to eq 1
  end
end

RSpec.configure do |config|
  ~~~
  Capybara.register_driver :selenium_chrome_headless do |app|
    browser_options = ::Selenium::WebDriver::Chrome::Options.new
    browser_options.args << '--headless'
    browser_options.args << '--no-sandbox'
    browser_options.args << '--disable-gpu'
    Capybara::Selenium::Driver.new(app, browser: :chrome, options: browser_options)
  end

  config.before(:each) do |example|
    if example.metadata[:type] == :system
      driven_by :selenium_chrome_headless, screen_size: [700, 700]
    end
  end
  ~~~~
end

我还打开了 Webdrivers Debug 日志记录。这是当时的日志。

解决方案

解决了。
这是因为没有安装谷歌浏览器。
对不起。
