當js_errors：false時，Poltergeist會拋出JS錯誤

Question

我有一個使用了poltergeist和水豚的大型測試套件。我不斷收到以下錯誤：

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). 

我很確定我設置了js_errors：false，但我仍然收到錯誤。我意識到最佳解決方案是修復JS，但我繼承了遺留代碼，修復了錯誤超出了我的角色範圍。我的規範助手文件看起來像這樣：

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 

我很困惑要去哪裏或者我是否忽略了JS錯誤。讓我知道是否有其他任何我可能忽略或忽略的信息。謝謝你的時間。

我不確定爲什麼你的代碼不起作用。我也有類似的JS錯誤，並做了以下（上this page提到（搜索js_errors）） - 基本上什麼萊昂納多Galani建議（我upvoted萊昂納多的回答是採取從-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 

我還測試了這種風格，和它的工作還有：

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

FWIW：我的錯誤（黃瓜測試）是這樣的：

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).

Answer 2

如果您僅使用register_driver的一個選項，則不需要散列。

另外你也不是js_errors:false而是:js_errors => false 或者你可以在外面設置散列，這樣你可以添加更多的選項，如果你將來需要的話。

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

@Leonardo Galani

根據ruby風格指南，您的語法評論是不正確的。所以答案也可以是{js_errors：false}。
