如何在每个测试场景后重新启动浏览器

标签: selenium cucumber capybara

我正在使用Cucumber与Capybara和Selenium-Webdriver一起测试Chrome扩展程序。

我的测试非常简单:

  @chrome_extension
    @javascript
      Scenario: Test1
      Given I open a browser
      And I close the browser
      When I do nothing
      Then nothing happens

步骤定义为:

require 'selenium-webdriver'

Given /^I open a browser$/ do
  visit 'http://google.com'
  STDERR.puts self
end

Given /^I close the browser$/ do
  page.driver.browser.quit
end

Given /^I do nothing$/ do

end

Given /^nothing happens$/ do

end

当我调用page.driver.browser.quit时,它会退出浏览器会话。但随后出现以下错误:

每种方案后重启浏览器的正确方法是什么?我需要每个测试尽可能无状态。

提前致谢!

使用Watir-webdriver,它与硒非常相似。

您可以使用钩子来完成此操作。对钩子进行一些研究以获得更好的理解,但是在项目的支持目录中,您需要创建一个钩子文件。我使用ruby和rubymine来运行我的测试,所以在你的环境中可能会有所不同。

你的钩子文件可能看起来像这样。

require 'watir-webdriver'



Before do
  @browser = Watir::Browser.new :chrome
end


After do
  @browser.close
end

然后,在运行每个方案之前,它将打开浏览器的实例并在方案完成时关闭浏览器。

清除Cookie并在After hook中刷新浏览器。例如,我在Watir-Webdriver

中使用它
After do |scenario|
  browser.cookies.clear
  browser.refresh
end

这可能有更优雅的方式,但我会考虑让每个场景都在自己的rake任务中并使用黄瓜中的标签,如下所示:

desc "Run scenario 1"
task :scenario_1 do
 cmd = "cucumber --tags @1"
 `#{cmd}`
end`

这样做可以完全达到您所追求的目标,因为Cucumber使用--tags参数开箱即用。

删除了java示例。

Capybara试图通过预测你想做的事来拯救你的工作。 Capybara在每一步都结束会议。如果您明确关闭浏览器会话,那么当capybara尝试清理cookie时,没有要清理的会话。

如果你不想让水豚处理这些事情,那就不用水豚就自己做吧。
