Ideas for additional coverage:
- Whitespace between and after the padding character
=, e.g. Uint8Array.fromBase64("Zg= =") and Uint8Array.fromBase64("Zg= = ").
Uint8Array.prototype.setFrom{Base64,Hex} doesn't modify the typed array when the input string is invalid.- Typed array is backed by a SharedArrayBuffer.
lastChunkHandling option is present, but set to undefined, e.g. the options object is {lastChunkHandling: undefined}.lastChunkHandling option is an invalid string value, e.g. the options object is {lastChunkHandling: "bad"}.alphabet option is present, but set to undefined, e.g. the options object is {alphabet: undefined}.alphabet and lastChunkHandling options are read in the correct order.- Extra bits with three element trailing chunk and strict chunk handling, e.g.
Uint8Array.fromBase64("ZZZ=", {lastChunkHandling: "strict"}). (The two element chunk case is already covered.)
