Use Case

As a node engineer
I want descriptive unit tests for command construction, and or commented code
So that I can prevent regression and understand the rules behind batchSize and limit options.

Unknowns

• How does getMore and find handle limit and batchSize correctly?
• The driver takes the Math.abs of batchSize, is this preventing silent errors?
• The find command used negative limits? Isn't that a special case for findOne?

Acceptance Criteria

Testing Requirements

• Improve the unit tests for command construction, find and getMore specifically
• Potentially reduce the type checking logic for command construction
  • ex. we don't need to see if batchSize is a number in mutliple places, we should check for nullish after it's been type checked.
