I agree and @aymericbouzy I have the same issue. Any ideas on how to fix it?
from jest-mongodb.
Same issue, I moved to mongodb-memory-server and everything works fine.
const startDB = () => new Promise((resolve) => {
const mongoServer = new MongoMemoryServer();
mongoServer
.getConnectionString()
.then(mongoUri => resolve({
mongoServer,
db: MongoDB.connect(mongoUri),
}));
});
from jest-mongodb.
I have the same issue. Why not having a separate database for each test suites (with a auto generated name) ? This kind of setup has worked well for me in the past.
from jest-mongodb.
I clean db collections in beforeEach
as well. There were a couple of reasons behind keeping current behavior.
Changing default behavior to clean everything before each test doesn't leave a chance to preserve documents between tests if users wish so. If you want to have a clean state, it's a matter of 1 line of code: await db.collection('name').deleteMany({})
But I'm not against this approach by any means, so PRs are welcome:) Meanwhile, I'll add some explanations to the README
from jest-mongodb.
I can open a separate issue for this, but when running tests in parallel with asynchronous code, cleaning the db in beforeEach does not work.
from jest-mongodb.
What I do in my own setup (not using this package) is using a fresh db in each test suite. I have something along these lines in my setup file :
beforeAll(async () => {
await connect(
`mongodb://localhost:27017/test_${randomToken()}`
)
})
afterEach(async () => {
await clear()
})
afterAll(async () => {
await disconnect()
})
from jest-mongodb.
