Not opposed to this, but do you know whether there were specific use cases for testConsole that won't be addressed as a result of this change?

I didn't see any uses for it when I did a search within the repo but I am not entirely sure. Could it be referenced indirectly somehow from C#? Although looks like the tests pass, so it probably isn't used anywhere.
Also this was a change that Larry did in his PR upon which this one is loosely based. @lewing do you know if this is used anywhere besides this file?

I'm pretty sure that when this is used (library-mono.js line 1950) the surrounding try catch block handles this.
try {
if (asset.name === attemptUrl) {
if (ctx.tracing)
console.log ("Attempting to fetch '" + attemptUrl + "'");
} else {
if (ctx.tracing)
console.log ("Attempting to fetch '" + attemptUrl + "' for", asset.name);
}
var fetch_promise = fetch_file_cb (attemptUrl);
fetch_promise.then (handleFetchResponse);
} catch (exc) {
console.error ("MONO_WASM: Error fetching " + attemptUrl, exc);
attemptNextSource ();

This PR aims to reorganize runtime-test.js and add the framework for the follow up PR which will add NodeJS support to WASM!
Why is this needed
The
runtime-test.jsfile is currently an amalgamation of functions and glue code that makes it hard to understand and hard to work with. The primary goal of this PR is to essentially refactor it such that it maintains the same functionality but in a more readable way. The most heavily affected aspect of the file is the way IO is handled. The secondary goal is to add theis_nodevariable along withrequireand other node specific methods for doing various operations which would be useful later on when adding NodeJS support to WASM.What's changed
