Nx: There is a new Jest memory leak after updating to v7.7

Created on 2 Apr 2019  ·  11Comments  ·  Source: nrwl/nx

Expected Behavior

My test suite runs without memory leaks.

Current Behavior

My test suite leaks between 50 and 100mb between each lib/app run.

Failure Information

I'm guessing there's a bug somewhere, but can't say for sure where. I've tried to exclude Jest itself from the equation because the memory leak seems to happen between suites and not within a suite.

Steps to Reproduce

All I did was update to @nrwl/nx v7.7 and all related dependencies as usual. It wasn't leaking in v7.6.

So I guess if anyone has a repo using Jest unit tests, that's all that is needed.

@nrwl/nx v7.7 includes a new version of jest-preset-angular (v7.x) which itself uses a new version of ts-jest. In the new version of ts-jest the option diagnostics is enabled by default. And this option cannot be overwritten since the jest builder of nx hard codes the ts-jest options. This leads to the following problems:

  1. The tests runs are much slower because the type-checking takes quite some time. And maybe there is a performance regression too (see https://github.com/kulshekhar/ts-jest/issues/908)
  2. More memory is needed, which causes your error

So it would be nice if there is an option added in nx to disable the diagnostics in ts-jest.

But anyway, if your app gets bigger at some you will reach the default memory limit in node.js (~1.5 GB). We already have that problem. As suggested in the @angular/cli repo we manually increase the memory limit for all test and build runs.

I'm aware that we will need more memory at some point but before the update, ~500mb was enough.

More memory being needed or even tests being slower is not really a problem. The problem is that no memory is being freed between test suites as you can see in my log.

I'll create a patch to disable diagnostics in ts-jest and report back.

I've created a patch to disable diagnostics but memory is still leaking. ):

Great debugging!

Can you reproduce with a more minmal project? It seems the way jest requires modules has some memory leaks when used with certain libraries?

https://github.com/facebook/jest/issues/8247

With my test project, I see this: which may have a more minor memory leak?

@FrozenPandaz it works fine locally actually. My logs are from GitLab runners.

I'm a bit short of time right now, but I'll see if I can come up with some repo. ):

Hi, I have the same error, but I'm running my test suite on TravisCI, here is the repo I'm working on:

https://github.com/llstarscreamll/angular-kirby

I have tried many things to fix the error, but nothing works... some links:

https://github.com/facebook/jest/issues/7647
https://github.com/facebook/jest/issues/2179

Here is the logs from my failed builds:

https://github.com/llstarscreamll/angular-kirby

On my local machine all the tests are green.

llstarscreamll picture llstarscreamll on 24 Sep 2019

Hi every one, my build is now passing!! I upgrade some dependencies and change TravisCI setup to this:

language: node_js
node_js: 12
dist: trusty
sudo: required
cache:
  npm: false
install:
  - yarn install --network-timeout 1000000
notifications:
  email: true
branches:
  except:
    - /^v\d+\.\d+\.\d+$/
script: ng test -i --ci --bail=1 --pass-with-no-tests

@llstarscreamll what dependencies did you upgrade to make the build pass?

Just confirming. It looks like the issue has been fixed in 8.5. Right?
