I would love it if we could have no typecasting to any in this PR

I just replaced all these instances with as ServerImplementationInterface.

any reason why we're using 423 or is it just an arbitrary spot to error?

This was just the value that Alex used for this test. It looks like it is just a value that is as random as possible to make the test realistic.

Curious if we could use Math.random() to test it more realistically.

I added an additional test to emit an error at a random position. I want to keep the old test in place too so that if it breaks then we have predictable code we can use to debug the issue.

what does value size represent?

I added a comment for this. It is // An upper bound on the amount of data included in the chunks

Summary:
The ultimate goal is to address the TODOs mentioned in
nodejs-bigtable/test/utils/readRowsImpl2.ts
Lines 161 to 163 in 34d138d
We are going to stack PRs onto this branch and then make one final merge into main.
Plan:
Currently there are 2 ReadRows mock services with a bunch of code that is duplicated. Before we address the excessive amount of if statements we need to take steps to eliminate similar services
ReadRowsImpl1andReadRowsImpl2. And before we eliminate duplicate code inReadRowsImplandReadRowsImpl2we should take some basic steps toward trying to eliminateReadRowsImpl2entirely by allowing for additional configurations to be made toReadRowsImplso that it can be reused.In this PR:
ReadRowsImpl,ReadRowsImpl2each rely on a different set of constants for chunk size, value size and chunks per response. Allowing them to be configurable inReadRowsImplgeneralizesReadRowsImpland is one step toward our plan of replacingReadRowsImpl2with a generalized version ofReadRowsImpl.ReadRowsServiceParametersandChunkGeneratorParametersso thatreadRowsImplandgenerateChunksonly need one parameter passed in.const keyFrom = 0;andconst keyTo = 1000;many times and we can just rely on a constant for these defined at the top of the file.ReadRowsImpl2by removingprettyPrintRequestbecause it is an exact duplicate of theprettyPrintRequestfunction inReadRowsImpl.Next steps:
ReadRowsImpl2.ReadRowsImpl2with a generalized version ofReadRowsImpl.ifstatements inReadRowsImpl. Introduce classes, generate unit tests, make the service more modular.
