因此，我开始创建一些 Ruby 单元测试，使用Selenium RC直接在浏览器中测试我的 Web 应用程序。我正在将Selenum-Client用于红宝石。我为所有其他硒测试创建了一个基类来继承。

这会创建许多 SeleniumDriver 实例，并且在每个实例上调用所有缺少的方法。这实质上是并行运行测试。

其他人是如何实现自动化的？

这是我的实现：

class SeleniumTest < Test::Unit::TestCase
  def setup
    @seleniums = %w(*firefox *iexplore).map do |browser|
      puts 'creating browser ' + browser
      Selenium::SeleniumDriver.new("localhost", 4444, browser, "http://localhost:3003", 10000)
    end

    start
    open start_address
  end

  def teardown
      stop
  end

  #sub-classes should override this if they want to change it
  def start_address
    "http://localhost:3003/"
  end

  # Overrides standard "open" method
  def open(addr)
    method_missing 'open', addr
  end

  # Overrides standard "type" method
  def type(inputLocator, value)
    method_missing 'type', inputLocator, value
  end

  # Overrides standard "select" method
  def select(inputLocator, optionLocator)
    method_missing 'select', inputLocator, optionLocator
  end

  def method_missing(method_name, *args)
    @seleniums.each do |selenium_driver|
      if args.empty?
        selenium_driver.send method_name
      else
        selenium_driver.send method_name, *args
      end

    end
  end
end

这可行，但如果一个浏览器失败，整个测试就会失败，并且无法知道它在哪个浏览器上失败。

Did you try Selenium Grid? I think it creates pretty good summary report which shows details you need. I may be wrong, as I didn't use it for quite a while.

I ended up modifying Selenium's protocol.rb to raise an AssertionFailedError with both the @browser_string and the message returned from the Selenium RC if the response didn't start with "OK". I also modified the http_post method to return the whole response body and the method_missing to return an array of return values for issuing get_X commands to the Selenium RC.

Add this code to the code in the question and you should be able to see which assertions fail on which browsers.

# Overrides a few Driver methods to make assertions return the
# browser string if they fail
module Selenium
  module Client
    class Driver
      def remote_control_command(verb, args=[])
        timeout(default_timeout_in_seconds) do
          status, response = http_post(http_request_for(verb, args))
          raise Test::Unit::AssertionFailedError.new("Browser:#{@browser_string} result:#{response}") if status != 'OK'
          return response[3..-1]
        end
      end

      def http_post(data)
        http = Net::HTTP.new(@server_host, @server_port)
        response = http.post('/selenium-server/driver/', data, HTTP_HEADERS)
        #return the first 2 characters and the entire response body
        [ response.body[0..1], response.body ]
      end
    end
  end
end

#Modify your method_missing to use seleniums.map to return the
#results of all the function calls as an array
class SeleniumTest < Test::Unit::TestCase
  def method_missing(method_name, *args)
    self.class.seleniums.map do |selenium_driver|
      selenium_driver.send(method_name, *args)
    end
  end
end

免责声明：不是硒专家。

Do you just want to know which browser failed, or do you want to run the test across all browsers and then report the total failures when it's done?

The former is pretty simple if you store the drivers by hash in your setup. (I'm sure there's a fancy-pants way to do this with Hash.inject, but I'm lazy.)

@seleniums = {}
%w(*firefox *iexplore).each do |browser|
  puts 'creating browser ' + browser
  @seleniums[browser] = Selenium::SeleniumDriver.new("localhost", 4444, browser, "http://localhost:3003", 10000)
end

Then change your core function to modify exceptions to include the name of the driver being used, something like:

@seleniums.each do |name, driver|
  begin
    driver.send method_name, *args
  rescue Exception => ex
    raise ex.exception(ex.message + " (in #{name})")
  end
end

Should get you close.

you need to treat every test independently. So if one test fails it will carry on testing other tests. Check out phpunit and selenium rc
