Improve Unit Test Coverage about vitess

[frouioui]

@GuptaManan100 vitess/go/history already has 100% coverage when I run the tests locally. Can you confirm?

@EshaanAgg, @GuptaManan100 is OOO, but I can confirm that it already has 100% of coverage on main, see the link below.

Can you please assign me vitess/go/acl?

[GuptaManan100]

@beingnoble03 You can start working on it. When you create a PR, just mention this issue, so that if anyone else looks they know you're working on the said part.

@GuptaManan100 sure, thanks.

@GuptaManan100 I was trying to understand the number of LFX mentee's that is proposed to be taken for the upcoming term? Is it just 1 or multiple people would be participating in different parts of the project?

On #14935 we have seen that the coverage of planbuilder is not being reported. On the base branch it is reported as 0.00% which leads to Code coverage failure as soon as we modify the lines in this package and subpackages.

Hey folks, I came upon this issue through the LFX Spring project idea page & interested to contribute here! From the issue, I understand that the main task is to add unit tests to various files under the project & improve test coverage (goal is 100%).

I'm a beginner in Go & have familiarity with very basic unit-testing through a personal project. I believe this would be a perfect way to level that up!

It would be a great help if you could point/list a few things out that would help me get me started here, to understand the project a bit more.
Thank you
