The function TypedDataUtils.encodeData has been thoroughly tested with all novel inputs I could think of. Each supported version (V3 and V4) have been tested independently with each input. There are also tests for each input that should have an identical encoding between V3 and V4, and each that should have non-matching signatures.

The structure of the tests is explained in a large inline comment at the start of the describe block for TypedDataUtils.encodeData.

The encodeData assertions that accompanied the signature tests have been deleted, as they're now redundant.

This depends upon #152 and #161. This PR is targeted at #161, and the first commit is #152. The second commit represents the actual contents of this PR.

This depends upon #152

The function `TypedDataUtils.encodeData` has been thoroughly tested
with all novel inputs I could think of. Each supported version (V3 and
V4) have been tested independently with each input. There are also
tests for each input that should have an identical encoding between
V3 and V4, and each that should have non-matching signatures.

The structure of the tests is explained in a large inline comment at
the start of the `describe` block for `TypedDataUtils.encodeData`.

The `encodeData` assertions that accompanied the signature tests have
been deleted, as they're now redundant.

This PR has been updated with more inline comments explaining what the tests are for.

// Reassigned to silence "no-loop-func" ESLint rule
// It was complaining because it saw that `it` and `expect` as "modified variables from the outer scope"
// which can be dangerous to reference in a loop. But they aren't modified in this case, just invoked.
const _expect = expect;

I really wish there was some way to silence this false positive. I didn't want to disable the rule for the whole file because it's genuinely useful still, but this is irritating.

Finished a first pass. Overall looks good. I left some inline change requests.

I'm going to do one more pass to confirm that the table is fully covered, and consider whether the inputs are exhaustive or not. Then we should be done here!

Why are we not using arrow functions for the callbacks in this test suite? mocha hangover?

Ah, right 😅
I was just following existing conventions (I think?). Probably better to use arrow functions, but maybe we can do this in one pass later on.
