ruby – Rspec`eq` vs`eql`在`expect`测试中

在rspec测试中使用eq和eql有什么区别？是否有区别：

it "adds the correct information to entries" do
  # book = AddressBook.new # => Replaced by line 4
  book.add_entry('Ada lovelace','010.012.1815','[e-mail]')
  new_entry = book.entries[0]

  expect(new_entry.name).to eq('Ada lovelace')
  expect(new_entry.phone_number).to eq('010.012.1815')
  expect(new_entry.email).to eq('[e-mail]')
end

和：

it "adds the correct information to entries" do
  # book = AddressBook.new # => Replaced by line 4
  book.add_entry('Ada lovelace','[e-mail]')
  new_entry = book.entries[0]

  expect(new_entry.name).to eql('Ada lovelace')
  expect(new_entry.phone_number).to eql('010.012.1815')
  expect(new_entry.email).to eql('[e-mail]')
end

解决方法

根据比较中使用的平等的类型,这里有微妙的差异.

从Rpsec文档：

Ruby exposes several different methods for handling equality:

a.equal?(b) # object identity - a and b refer to the same object
a.eql?(b) # object equivalence - a and b have the same value
a == b # object equivalence - a and b have the same value with type conversions]

eq使用==运算符进行比较,eql忽略类型转换.
