I'm lost, I have been searching for good resources but I can't find any. How to do unit testing for a back-end NodeJS, ExpressJS, Firestore, RESTful app? What tools to use? How to mock data? I don't want to have a test database for testing, I want to mock data. Can any one help me?
Example of an endpoint:
router.post("/color", async (request, response) => { if(Object.keys(request.body).length === 0) return response.status(406).send("Ups... There was missing data."); try { await db.collection('Colors').add({ realColor: request.body.realColor, colorMap: request.body.colorMap }); response.status(201).send("Success! A color was creted!"); } catch (error) { console.log(error); response.status(400).send("Ups... A color was NOT creted!"); } });

Did you find your way through it? I'm curious about it too.
Sadly, no. We just mock data with sinnon, and check response statuses, but i dont think its correct unit tests
Maybe use something like Firebase Emulator or Firebase Mock?
did you find any way guys ??
