问题描述

在 rspec 测试中使用 eq 和 eql 有什么区别?是否有区别:

What is the difference between using eq and eql in rspec tests? Is there a difference between:

it "adds the correct information to entries" do
  # book = AddressBook.new # => Replaced by line 4
  book.add_entry('Ada Lovelace', '010.012.1815', '[email protected]')
  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('[email protected]')
end

和:

it "adds the correct information to entries" do
  # book = AddressBook.new # => Replaced by line 4
  book.add_entry('Ada Lovelace', '010.012.1815', '[email protected]')
  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('[email protected]')
end

推荐答案

根据比较中使用的相等类型，此处存在细微差别.

There are subtle differences here, based on the type of equality being used in the comparison.

来自 Rpsec 文档:

From the Rpsec docs:

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.

eq uses the == operator for comparison, and eql ignores type conversions.
