Add tests

[BigBlueHat]

• Add mocha/chai tests for stdin, files, & HTTP.
• Use deep.equal instead of item checks.
• Remove timeout.
• Remove use of old school aliases.
• Rename folder from fixtures to data.
• Make test input data more real.

[davidlehn]

• Should add a github action to run these.
• Is "fixture" term use ok? I thought that was more the broader testing setup vs only the test data here. Can be changed later if needed.
• Should perhaps target a different branch. It's overlapping with other PRs.

Ah. I see. I had the branches stacked locally, but GitHub ignores that when you make a PR... It's possible to later edit that (or maybe set it via the CLI), but I forgot to do that. Sorry for the confusion.

@davidlehn GitHub Action added. Obligatory CHANGELOG.md conflict added also...

I've changed the base to main which gets around the CHANGELOG.md conflict...until #16 is merged.

Hit the title edit button and you can change the target branch.

Getting a bit confused with the multiple prs and what was changed where. Like the node_modules ignore is here too.

[davidlehn]

360 is the default. I'd hope tests don't take that long! Maybe this should be lower or removed if default is fine.

This can be a full check too right?

Suggested change

	data.should.be.an('object');
	data.should.have.property('@context');
	data.should.deep.equal(JSON.parse(fixtureData));
