如何檢查字符串是否包含數組中的所有字符串？

Question

我有

last_email_sent.body.should include "Company Name"
last_email_sent.body.should include "SomeCompany"
last_email_sent.body.should include "Email"
last_email_sent.body.should include "test@test.pl"

我想用數組替換它

last_email_sent.body.should include ["test@test.pl", "Email"]

Answer 1

您可以簡單地循環：

["test@test.pl", "Email"].each { |str| last_email_sent.body.should include str }

或者，如果您喜歡匹配器語法，請編寫自己的匹配器：

RSpec::Matchers.define :include_all do |include_items|
  match do |given|
    @errors = include_items.reject { |item| given.include?(item) }
    @errors.empty?
  end

  failure_message_for_should do |given|
    "did not include \"#{@errors.join('\", \"')}\""
  end

  failure_message_for_should_not do |given|
     "everything was included"
  end

  description do |given|
    "includes all of #{include_items.join(', ')}"
  end
end

像這樣調用它：

last_email_sent.body.should include_all ["test@test.pl", "Email"]

Answer 2

嘗試這個

["test@test.pl", "Email"].all?{ |str| last_email_sent.body[str] }.should == true

Answer 3

我喜歡將這樣的數組放在實用程序方法中：

規格/支持/ utilities.rb

def email_body_elements
  ["Company Name", "Some Company", "Email", "test@test.pl"]
end

投機/ your_spec.rb

email_body_elements.each do |element|
  last_email_sent.body.should include element
end

Answer 4

如果last_email_sent.body恰好是Company Name SomeCompany test@test.pl Email ：

last_email_sent.body.should include ["Company Name", "SomeCompany", "test@test.pl", "Email"].join(" ")
