设置方法的watir无效参数错误

标签： ruby watir watir-webdriver

我正在使用watir和ruby来编写页面对象模式UI框架。这工作正常，直到我进行捆绑更新

我有一个yml文件代表像这样的页面

username:
 field: text_field
 attribute: name
 value: username
 default:
 operations:
  - exists?
  - set

一个页面对象方法生成器，它将其输入

def generate(elements)
    elements.each do |element|
        element[1]['operations'].each do |operation|
            if operation.eql? 'set'
                default = element[1]['default']
                self.class.send(:define_method, "#{element[0]}_#{operation}") do |default=''|
                    @b.send(element[1]['field'], element[1]['attribute'].to_sym, element[1]['value']).send(operation, default)
                end
            else
                self.class.send(:define_method, "#{element[0]}_#{operation}") do
                    @b.send(element[1]['field'], element[1]['attribute'].to_sym, element[1]['value']).send(operation)
                end
            end
        end
    end
end

当我对chrome运行watir测试时，这似乎工作正常。但是，当我的浏览器是Firefox时，我收到错误Expected [object Undefined] undefined to be a string (Selenium::WebDriver::Error::InvalidArgumentError)

生成方法中的第6行抛出该错误

这就是我将yml传递给generate方法

的方法 
def initialize(browser)
    file_path = File.expand_path("../config/signin.yml", __FILE__)
    elements = YAML.load(File.read(file_path));
    super(browser, elements)
end

watir version 6.8.0 selenium-webdriver版本3.5.1 geckodriver-helper 0.0.3

更新

1 个答案:

答案 0 :(得分：0)

我查看了我发布的问题以及我的代码。意识到我提到了bundle update搞砸了可执行代码，我看了看Gemfile。我发现罪魁祸首是geckodriver-helper，这违反了我通过geckodriver安装的homebrew。

获得的经验：通过自制软件或gemfile安装，但不能同时安装
