Hi, I’ve split my tests up so they run in different stages, however, using the config below, ‘npm ci’ and ‘npm run build’ are run before each test. Is it possible to run these scripts only once? My aim is to speed up the pipeline by running our unit and integration tests separately, so if one fails, it can be run independently without running the other. Our cypress integration tests are particularly slow, and can take up to 30 minutes. Any suggestions?
```auto

# Ubuntu 16+ does not install this dependency by default, so we need to install it ourselves

before_install:
- npm config set //registry.npmjs.org/:_authToken=$NPM_TOKEN

If you wish to skip creating build artifacts in succeeding stages and rather use ones created by a preceding stage, you can transfer them using workspaces:

Thanks for the advice, much appreciated. I have changed my config file to be:
```auto
language: node_js
node_js:
- 12
addons:
apt:
packages:
# Ubuntu 16+ does not install this dependency by default, so we need to install it ourselves
- libgconf-2-4
before_install:
- npm config set //registry.npmjs.org/:_authToken=$NPM_TOKEN
cache:
directories:
- ~/.npm
- ~/.cache
defaults: &defaults
script:
- npm run $STAGE_NAME
jobs:
include:
- stage: build
script:
- npm ci
- npm run build
workspaces:
create:
name: build1
- stage: test
workspaces:
use: build1
env:
- STAGE_NAME="test"
<<: *defaults
- stage: integration
workspaces:
use: build1
env:
- STAGE_NAME="integration"
<<: *defaults
```
but the stage called “integration” still runs `npm run build` before it starts running its own script. Could you advise me how I can speed this up at all? Any suggestions would be very welcome! Thanks again.

Could you link to the build? Can’t quite say what’s happening without seeing it.
My best blind guess is the extra command is [the default `install` command for `language: node_js`](https://docs.travis-ci.com/user/languages/javascript-with-nodejs/). To skip it, specify `install: skip` in the specific job(s).

Ah, I think I have it, there was a build command in the package.json, so it wasn’t coming from the travis.yml file, apologies for the mixup. Could you recommend anyway of making this faster, do I have the correct files cached etc? Thanks for any advice!

I don’t know much about NPM and you didn’t show me the build for me to see what’s happening.
So all I can say is I see your workspace is currently empty. You probably want to add your build artifacts and/or NPM cache locations to it – depending on what your later stages need to be present.
