常见的想当然
A parser configured with `headers: true` still makes column lookups expose only data rows, so the header names are never treated as a data value.
这是本样本作者记下的、开发者或模型在此处通常会有的预期。下面的契约才是真正运行过的东西。
契约
- assert CSV.parse("id,name\n1,alice\n2,bob\n", headers: true, return_headers: true)["name"] == ["name", "alice", "bob"]
- assert CSV.parse("id,name\n1,alice\n2,bob\n", headers: true)["name"] == ["alice", "bob"]
- assert CSV.parse("id,name\n1,alice\n", headers: true, return_headers: true).first.to_a == ["id", "name"]
