Question

我有一个大型测试套件，使用了poltergeist和capybara。我一直收到以下错误：

One or more errors were raised in the Javascript code on the page. If you don't care about
these errors, you can ignore them by setting js_errors: false in your Poltergeist
configuration (see documentation for details).

我很确定我已经设置了js_errors：false但我仍然遇到错误。我意识到最佳解决方案是修复JS但我继承遗留代码并修复错误超出了我的角色范围。我的规范帮助文件如下所示：

ENV["RAILS_ENV"] ||= 'test'
require File.expand_path("../../config/environment", __FILE__)
require 'rspec/rails'
require 'rspec/autorun'
require 'capybara/poltergeist'
Capybara.javascript_driver = :poltergeist

Capybara.register_driver :poltergeist do |app|
  Capybara::Poltergeist::Driver.new(app, {js_errors: false})
end

Capybara.current_driver = :poltergeist

Capybara.configure do |config|
  config.match = :one
  config.exact_options = true
  config.ignore_hidden_elements = true
  config.visible_text_only = true
end

Dir[Rails.root.join("spec/support/**/*.rb")].each {|f| require f}



RSpec.configure do |config|
  config.infer_base_class_for_anonymous_controllers = false
  config.order = "random"
end

我很困惑到哪里去或者我是否适当地忽略了JS错误。如果有其他任何我可能忽略或忽略的信息，请告诉我。谢谢你的时间。

我不确定为什么你的代码不起作用。我刚刚有一个类似的JS错误，并做了以下（如this page上所述（搜索js_errors）） - 基本上莱昂纳多加拉尼提出的建议（我赞成莱昂纳多的答案，从-1到0）：

require 'capybara/poltergeist'
Capybara.javascript_driver = :poltergeist

options = {js_errors: false}
Capybara.register_driver :poltergeist do |app|
  Capybara::Poltergeist::Driver.new(app, options)
end

我也测试了这种风格，它也很有效：

Capybara.register_driver :poltergeist do |app|
  Capybara::Poltergeist::Driver.new(app, {js_errors: false})
end

FWIW：我的错误（在Cucumber测试中）看起来像这样：

Capybara::Poltergeist::JavascriptError: One or more errors were raised in the 
Javascript code on the page. If you don't care about these errors, you can ignore 
them by setting js_errors: false in your Poltergeist configuration (see 
documentation for details).

@Leonardo Galani

根据ruby样式指南，您的语法注释不正确。所以答案也可能是{js_errors：false}。

Answer 3

我遇到了同样的问题，js_errors: false不能解决问题，但是phantomjs_logger: "/dev/null"是！

Answer 4

如果您只使用register_driver的一个选项，则不需要哈希值。

你还不是js_errors:false而是:js_errors => false 或者您可以在外部设置散列，以便在将来需要时添加更多选项。

options = {:js_errors => false}
Capybara.register_driver :poltergeist do |app|
    Capybara::Poltergeist::Driver.new(app, options)
end

当js_errors：false时，Poltergeist抛出JS错误
