问题：

Selenium WebDriver错误：会话id无效

艾意蕴
2023-03-14

我使用Selenium WebDriver和Chrome在我的应用程序中进行功能测试。我已经用rspec、capybara和selenium成功地设置了多个rails应用程序，但我不知道为什么这个不能工作。

问题是：当我第一次运行特性测试时，它会按照计划工作。但是，如果我再次运行它，selenium会崩溃，并出现以下消息：

Selenium：：WebDriver：：Error：：NoSuchDriverError：无效会话id（驱动程序信息：ChromeDriver=74.0.3729.6(255758ECCF3D244491B8A1317AA76E1CE10D57E9-Refs/Branch-Heads/3729@{#29}）,Platform=Mac OS X 10.14.3 x86_64)

我可能会补充一点，功能测试在其他应用程序中工作得很好，所以这不是Chrome/ChromeDriver兼容性问题。

我已经在这方面工作了好几天了，我不知道发生了什么

这是我的配置：

    null 
Capybara.register_driver :chrome do |app|
  Capybara::Selenium::Driver.new(app, browser: :chrome)
end

Capybara.register_driver :headless_chrome do |app|
  capabilities = Selenium::WebDriver::Remote::Capabilities.chrome(
    chromeOptions: { args: %w(headless disable-gpu) }
  )

  Capybara::Selenium::Driver.new app,
    browser: :chrome,
    desired_capabilities: capabilities
end

Capybara.javascript_driver = :headless_chrome
Capybara.default_max_wait_time = 15

Chromedriver在测试中反复使用相同的会话id。这就是为什么第一次，测试通过，但如果我再次开始，chromedriver将使用完全相同的会话id，这就是我认为导致问题的原因。我记录了Selenium的操作，它确实发送了DELETE，所以我不明白。
