Improve test command coverage for path argument issues

[noaabarki]

Describe the solution you'd like
Add tests for failures flows regarding path argument in test commanddatree test <path>

Basic use cases to cover

Case: Given path contains zero files

• should print "No files detected”

Case: Given path contains YAML files that are not Kubernetes resources

Empty evaluation results

• should create evaluation
• should request evaluation
• should print returned results

Case: Given path with multiple resources in single file

• should create evaluation
• should request evaluation
• should print returned results

Requirements
Golang basic level.

Hey @noaabarki I would like to try this :)

[noaabarki]

@Abhra303 awesome, it's yours 👑

Hello @noaabarki,

#381 , #382 and this issue are very close to each other. I mean, the test codes might be very similar. So would you mind if I cover all the test cases in a single PR?

[noaabarki]

@Abhra303, yes you're right they are very close, do you prefer to do it all together?
The reason why I separated them was that I was worried we'd end with a giant PR. Small and contained PRs are always better, especially when it comes to unit tests in Go which are usually hard to read and understand.

Hmm, That's sensible.
Okay, I will make separate PRs for them. Would that be okay?

Sounds good :)
