This repo has examples of how to do Prisma unit and functional testing with NodeJS and Typescript.

Blog post: https://dev.to/eddeee888/how-to-write-tests-for-prisma-with-docker-and-jest-593i

Requirements

• Docker
• Docker compose
• Node 12.x
• yarn or npm

Get started

Install packages by running the following:

$ yarn install

How it works

We run the dev app and test in 2 different containers, managed by docker-compose.yml and docker-compose.test.yml respectively.

To run tests, we build the test container and database. Run this in your terminal:

$ yarn docker:test:build
# Alternatively, you can run the following command directly on your host terminal:
# docker-compose -f docker-compose.test.yml build --no-cache

Then, run the following command to drop the database ( if exists ) and run migrations on the test database:

$ yarn docker:test:prepare
# Alternatively, you can run the following commands directly on your host terminal:
# docker-compose -f docker-compose.test.yml run --rm server ./scripts/wait-for-it.sh database:3306 -- yarn ts-node src/prisma/reset.ts
# docker-compose -f docker-compose.test.yml run --rm server yarn prisma:up

Now, run the following to run unit tests and functional tests:

$ yarn docker:test:run
# Alternatively, you can run the following commands directly on your host terminal:
# docker-compose -f docker-compose.test.yml run --rm server ./scripts/wait-for-it.sh database:3306 -- yarn test
# yarn docker:test:prepare
