// Integration test -> unit test + database test // we can how application interact with kafka or database // dont mock out any external service call, running all external service

// downside // slower to execute // it add complixity // local setup is required

// npm init -y && npx tsc --init // mkdir src dist // changes made in tsconfig.json // npm i @types/express // start docker locally -> // docker run -p 5432:5432 -e POSTGRES_PASSWORD=mysecretpassword -d postgres // npx prisma migrate dev --name init // npx prisma generate // npx prisma studio

// take down local database // docker ps // docker kill container_id

// we can write many commands in docker like for kafka, redis, postgres
