Jest did not exit one second after the test run has completed using express

Question

I\'m using JEST for unit testing my express routes.

While running the yarn test all my test case are getting passed, but I\'m getting an error

Answer 1

My problem was solved by this code:

beforeAll(done => {
  done()
})

afterAll(done => {
  // Closing the DB connection allows Jest to exit successfully.
  mongoose.connection.close()
  done()
})
