Tighten up a bunch of types in test.dart.

Tighten up a bunch of types in test.dart.

This doesn't get rid of all implicit dynamic and casts, but it covers
many of them.

Also did some minor modernization when I noticed it:

- Using "var" for local variables where inference does the right thing.
- camelCase for variable names.
- More collection literals.

There are (or should be!) zero behavioral changes.
