Tests

cd into a package and run the tests, for exmaple:

cd ./packages/ast
yarn test:watch

If you are doing major development, you'll probably want to open up a few windows, and run tests in at least these three packages:

the ast package:

cd ./packages/ast
yarn test:watch

the parser package:

cd ./packages/parser
yarn test:watch

the telescope package will also generate more fixtures, so you can see the end result.

cd ./packages/telescope
yarn test:watch
