watir set 方法的无效参数错误
watir invalid argument error for set method
我正在使用 watir 和 ruby 编写页面对象模式 UI 框架。在我执行 bundle update
之前，一切正常
我有一个代表这样一个页面的 yml 文件
username:
field: text_field
attribute: name
value: username
default:
operations:
- exists?
- set
以及一个页面对象方法生成器，它被送入
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 运行 对 chrome 进行 watir 测试时，这似乎工作正常。但是，当我的浏览器是 firefox 时，出现错误 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 传递给生成方法的方式
def initialize(browser)
file_path = File.expand_path("../config/signin.yml", __FILE__)
elements = YAML.load(File.read(file_path));
super(browser, elements)
end
watir 版本 6.8.0

我查看了我自己发布的问题以及我的代码。意识到我提到 bundle update 搞砸了可执行代码后，我查看了我的 Gemfile。我能够发现罪魁祸首是 geckodriver-helper，它破坏了我通过 homebrew.
geckodriver
经验教训：通过自制软件或 gemfile 安装，但不能同时安装
