Perhaps in the jest test, create query behaves lazy. (Is my guess right? ??) Can you tell me how to solve it?

No it’s not lazy as you’re using

await

. This should work fine. Can you log

school

inside the

signUp

method and check?

You are right. I solved the problem. I was using it incorrectly when using dot env cli.

//package.json
"test:local": dotenv -e ./dotenv/local.env jest --detectOpenHandles --forceExit --runInBand  // only  jest (option not working) 

"test:local": dotenv -e ./dotenv/local.env -- jest --detectOpenHandles --forceExit --runInBand //  jest --detectOpenHandles --forceExit --runInBand

There are several tests. I initialize the database every test. I was mistaken because there was data left in the database.
