Smoke Test

mkdir t2-no-package.json && cd t2-no-package.json;
t2 init;
rm {package.json,.tesselinclude};
ls -ah;
t2 run index.js;

Observed:

Expected Outcome

A new project is created, the package.json and .tesselinclude are deleted (the latter is not necessary), the index is deployed without failing to find a package.json
