How to run parallel tests with AVA and Mongoose

Based on the discussion for handling concurrency and atomic tests (https://github.com/avajs/ava/issues/472)

I would like the best approach to test my server endpoints in parallel.

I'm using a koajs server and a mongodb database (mongoose)

I'm trying to use Mockgoose (https://github.com/mccormicka/Mockgoose) to create a temporary in-memory mongod that will not persist the data

I wanna know if creating a separate database for each test is a good approach?

Is there any example of this?

Solution

  • Not for AVA, but for Jest, you can use Jest testEnvironment setting to create a new environment which builds a mongodb database for each test, using the library mongodb-memory-server.
