rABC6c5a3dd84f6a: [Cashtab] [Chronik] [Tx Gen] Parse XEC send value

Summary

As per T2447, this is part of a series of diffs to refactor the transaction generation process.

This diff is a standalone utility function which parses parameters for both one to one and one to many send XEC transactions, aggregates the total send value (in case of one to many) and then checks whether the final send value is above dust.

This diff does not change any existing functionality within the codebase. Once all the utility functions are accepted, then there'll be a final set of diffs to refactor the existing sendXec() function which is getting quite large and cumbersome to maintain.

Test Plan

npm start
npm test
observe the successful execution of new useBCH.test.js unit tests

Could you add a pseudocode description of how you would like the final sendXec() function to work, including each component function and a short description of its inputs and outputs? We have a skeleton in T2447 but I think this should really be its own task. We might come back and edit it a bit as these diffs land and we see more about the best way to get this done.

I'd like to see the context more fleshed out before approving this initial step.

695 ↗	(On Diff #33988)	We should be able to capture the specific error msg in the unit tests, as we'll want to throw a notification with the specific error msg in the app (not just `console.log` it)
700 ↗	(On Diff #33988)	See above
705 ↗	(On Diff #33988)	Return a specific error msg

1471 ↗	(On Diff #33988)	Situation here where we will have to check for a `null` return value after calling this function. Also, Cashtab doesn't know what caused this error -- only a user reading the `console.log` statement would be able to figure it out. Whatever error causes `sendXec()` to fail should be thrown in a notification. So, we should be capturing the specific errors thrown in this function for the unit test failures.

web/cashtab/src/hooks/__tests__/useBCH.test.js
678 ↗	(On Diff #34029)	The parameter `bchValue`, used to pass the single send XEC amount in `Send.js`, is a string. It's okay if this function also works taking a number input, but the unit test should match the app -- i.e. `parseXecSendValue(false, '550', null)...`
