Jest/Puppeteer Test Suite failing to run on example

Questions

Hello, I’ve been looking to run the example test suite posted in https://docs.daml.com/getting-started/testing.html with the template create-daml-app.

After following the steps and running npm test, Console throws some errors:

Ex: Party names are unique
thrown: “Exceeded timeout of 60000 ms for a hook”

for all written tests, and afterward

Test suite failed to run
spawn npm-cli.js ENOENT
Test suite failed to run
TypeError: The “pid” argument must be of type number. Received type number (NaN)

The last statement in console.debug before failing is “Starting npm start”, so I suspect it’s something to do with spawning the npm start process in beforeAll(). Not sure how to go about troubleshooting this, so any help is appreciated!

Running on Ubuntu 20.04 LTS.

Hi @mprohorov1,

I’m not very familiar with this part; would you mind sharing a bit more details about exactly what you’ve done, and maybe a bit more of the console output, preferably within triple-backticks?

Hey @Gary_Verhaegen ,

I ended up finding the point of failure and resolving this. In the beforeAll() function:

uiProc = spawn("npm-cli.js", ["run-script", "start"], {
   env,
   stdio:"inherit",
   detached: true,
});

changed to

uiProc = spawn("npm", ["run-script", "start"], {
   env,
   stdio:"inherit",
   detached: true,
});

So, it’s likely just a mismatched name in the PATH.
