Please review the Jest test code. Basecamp to-do is here.

@jessestorbeck @hzeng2 -- reminder.

@Weiiirrr -- I could get all test pass. However I had to run yarn add -D jest-environment-jsdom whenever it's the first time I test in a folder (i.e. pushkin-exptemplates-basic, pushkin-exptemplates-lexical, or pushkin-exptemplates-reading). Do you think it's something that could be configured like this? To avoid manually running yarn add -D jest-environment-jsdom often.

@Weiiirrr -- you should be able to add jest-environment-jsdom to the repo, following your instructions. Or follow @hzeng2 's suggestion above. Can you please make that update, commit, and push before we merge? Thanks!

Hi @hzeng2, I revised the configuration and pushed it. Can you test it again to check if it works? Thank you!
