@shelf/jest-mongodb does not work with TypeScript

[francesco-albanese]

Here the config I am using for jest in jest.config.js:

module.exports = {
  transform: {
    '^.+\\.jsx?$': 'babel-jest',
    '^.+\\.ts?$': 'ts-jest'
  },
  rootDir: './lib',
  roots: ['<rootDir>'],
  moduleFileExtensions: ['ts', 'js', 'json', 'node'],
  preset: "@shelf/jest-mongodb"
};

Jest fails to run tests just saying "Determining test suites to run..."

Works if I replace preset: "@shelf/jest-mongodb" with preset: "ts-jest"

We use it with a Typescript setup, our jest.config.js looks like this:

const { defaults: tsjPreset } = require('ts-jest/presets')

module.exports = {
  preset: '@shelf/jest-mongodb',
  // ...some other non related config values...
  transform: tsjPreset.transform,
}

// EDIT: But as you see, we're not using babel, so you might need to configure ts-jest differently, in order to pick up your babel preset: Maybe this helps - https://kulshekhar.github.io/ts-jest/user/config/babelConfig

Actually I copy pasted the stuff about babel from another project, this is a node project strictly so there is no need to use babel-jest.

I replaced the configuration with this:

const { defaults: tsjPreset } = require('ts-jest/presets')

module.exports = {
  transform: tsjPreset.transform,
  rootDir: './lib',
  roots: ['<rootDir>'],
  moduleFileExtensions: ['ts', 'js', 'json', 'node'],
  preset: "@shelf/jest-mongodb"
};

but still does not work. Keeps on saying "Determining test suites to run..."

Never mind, it was just the Docker image node:alpine which apparently is not compatible with mongodb-memory-server

@francesco-albanese You left this issue open. Sounds like you should be able to close it.
