* Install test dependencies. * Add initial test files. These files were created using a simplistic AST manipulator using `recast` to preserve formatting. There's bound to be a huge chunk of errors, but this serves as a good start. QUnit was replaced with Mocha, with ES2015 imports running via `esm`. As far as possible, QUnit-specific syntax has been replaced with Mocha's `describe` and `it`, while the native Node.js `assert` module is used for assertions. Files in the `test` directory ending in `.test.js` will be treated as test files. * Add initial passing files to test run.
