## _Appeal To Importance_

This needs to land this right now to fix a bug / make a milestone / my hair’s on fire; can't you understand that there's no time for tests??

## _Sufficient Coverage Argument_

This CL already has at least one unit test, and therefore should be considered reasonably tested.

## _Argument From Historical Laziness_

This other pre-existing system doesn’t have tests, so my similar new system shouldn’t need any either!

## _Missing Infrastructure Argument_

There’s no good way to write these tests easily, so I shouldn’t need to write them.

## _Insufficient Coverage Argument_

The tests requires extensive mocking (of servers, RPCs, filesystems, 3d party libs with their own side-effects, GUI) and would thus not test the real system but a limited fictional subsystem. Such tests would be totally irrelevant so they need not be written.

## _Just a Refactoring Argument_

All functionality in this patch is already entirely covered by preexisting tests. Trust me.

## _Promise Of Future Work_

I pinky-swear that I will write a follow-up CL that adds tests, just as soon as I fix these other things first...

## _The Proof is in the Pudding_

We're already using this for releases. It clearly works so we don't need to write tests. At this point we empirically have full coverage and just found a couple minor bugs.﻿
