[Tracking Issue] Improve the test coverage

[utam0k]

The current youki has far too few unit tests.
We are planning to increase the test coverage for the following files.
Perhaps this is a very good opportunity to understand the code and how it works. If you are interested, please comment on the issue and declare the files you want to test.

• src/spec.rs
• src/namespaces
• src/cgrpups/devices.rs(assigned @tsturzl) Improved testing, property testing, device tests #75
• src/cgroups/manage.rs
• src/create.rs(assigned @TinySong)
• src/capability.rs (assigned @sensaiankit)
• src/rootfs.rs(assigned @constreference )
• src/tty.rs(assigned @constreference ) Add unit tests for tty module #102

Hi, @utam0k I'd be happy to take capability and tty

[utam0k]

@constreference
Thanks for your interest! Sorry, the capability.rs was already assigned to @sensaiankit through a DM exchange. I forgot to update it.
tty.rs is definitely something you should do, but it is the least maintained and may need refactoring. It may be a bit of a challenge, but I'd love to see it done.
Can I assign tty.rs to you?

[ghost]

Sure !, I'll give it a shot !

[utam0k]

I assigned it to you. Looking forward to your PR!

[tsturzl]

I can take the device cgroup controller testing. I'll just implement the same tests I had done on the other controllers.

[utam0k]

@tsturzl Ok! I assigned you.

@utam0k I would like to take src/create.rs or src/namespaces tests

[utam0k]

@TinySong Thanks for your interest!
I'd love to have you do the create.rs, but it might be a bit challenging. If you have the time and seem to be quite interested, I'd like to ask you to do create.rs. This will be the core youki file.

[bobsongplus]

@utam0k yeah, I love to take that. If i encounter difficulties, I will ask you again，thanks

[utam0k]

@TinySong Sure. I assigned you to create.rs.

[ghost]

@utam0k I would like to take rootfs if it's available

[utam0k]

@constreference Of course. I'm looking forward to working with you.

Youki's codes have changed a lot, so I'll close it once.
