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','augusta.king@lovelace.com')
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('augusta.king@lovelace.com')
end
和：
it "adds the correct information to entries" do
# book = AddressBook.new # => Replaced by line 4
book.add_entry('Ada Lovelace','augusta.king@lovelace.com')
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('augusta.king@lovelace.com')
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.
