Testing (zh-CN)

本文主要讲述了在no_std环境下进行单元测试和集成测试的方法。我们将通过Rust的自定义测试框架来在我们的内核中执行一些测试函数。为了将结果反馈到QEMU上，我们需要使用QEMU的一些其他的功能以及bootimage工具。

error[E0152]: duplicate lang item in crate core (which rustc_std_workspace_core depends on): CStr.

= note: the lang item is first defined in crate core (which spin depends on)

My English is very poor, please forgive my expression。When I follow the blog,I have encountered this problem and don't know how to solve it.I have also checked some information, but I cannot solve it. I think it is a version issue.

[HaZ-K]

I solve it

[phil-opp]

How did you solve it? Maybe this helps other people that have a similar issue.

To Haz-K: 你是不是删除 panic = "abort" 之后解决的问题？是把下文的为了修复这个问题提供的方案，以为是可以修复 note 里面的那个 bug 所以照做后又把 panic="abort" 又加回去了吗？

Is that relating to duplicate lang item mentioned in the note? That might cause by misunderstanding of "to solve this" afterwards. I also think that relating to the errors not the ignore of test runner. Maybe emphasize in the note, at this stage please delete panic = "abort" until the bug is fixed? Well that's not a huge problem...

in src/lib.rs

add #![no_std] after #![cfg_attr(test, no_main)]
