在`expect`测试中，Rspec`eq`对`eql`

在rspec测试中使用eq和eql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', '010.012.1815', '[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 

Answer 1

根据比较中使用的相等类型，这里存在细微差别。

来自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，而eql忽略类型转换。
