well, the question is what do you expect it to do, and what you do with the result?
This will compile all of our dev packages. they are not used directly but released using public packages or served using the babylon server.
What are you trying to do?
In general my question about right expectation of this command. What is this should to show and what is this should not to show?
In my local task I want to run unit tests.
I forked the repo, clone, run npm install and check npm run build:dev. After this I run npm run test:unit and got this:
Test Suites: 10 failed, 7 passed, 17 total
Tests: 35 passed, 35 total
Snapshots: 0 total
Time: 3.907 s, estimated 22 s
Ran all test suites.
I think it is not correct output, I didnt change anything but some of tests are failed. As I can see, some trouble with import âWebGPU/webgpuMaterialContextâ. Probably I skip some steps, I dont knowâŚ

The unit tests compile typescript, so it has little to do with the build:dev command. jest seems to not like the syntax you have used (though it is es2021 conform). This is more a jest issue than the build:dev command.
The build:dev command builds all of the dev packages. thatâs about it. it is not used by the tests, and is not used when hosting the local babylon-server.
i just realized you wrote that you didnât change anything and the tests are failing.
What node/npm are you running? have you updated dependencies lately?
Yep, I just hoped that build:dev says me if I had errors with installed packages. And if build successfull, so I expect that other commands should work also.
sadly thatâs not the case. jest uses its own typescript compiler (and target). Apart from that everything else uses the same tsconfig, so it should be good to go.
The Jest trying to say smth, but I am not sure that any of suggested decision is acceptable in my case

â Test suite failed to run
Jest encountered an unexpected token
Jest failed to parse a file. This happens e.g. when your code or its dependencies use non-standard JavaScript syntax, or when Jest is not configured to support such syntax.
Out of the box Jest supports Babel, which will be used to transform your files into valid JS based on your Babel configuration.
By default "node_modules" folder is ignored by transformers.
Here's what you can do:
⢠If you are trying to use ECMAScript Modules, see https://jestjs.io/docs/ecmascript-modules for how to enable it.
⢠If you are trying to use TypeScript, see https://jestjs.io/docs/getting-started#using-typescript
⢠To have some of your "node_modules" files transformed, you can specify a custom "transformIgnorePatterns" in your config.
⢠If you need a custom transformation specify a "transform" option in your config.
⢠If you simply want to mock your non-JS modules (e.g. binary assets) you can stub them out with the "moduleNameMapper" config option.
You'll find more details and examples of these config options in the docs:
https://jestjs.io/docs/configuration
For information about custom transformations, see:
https://jestjs.io/docs/code-transformation

Via PhpStorm (from them interface) I can run some unit tests from the test file directly.
But interesting â it.each() is not working, and in the source code i didnt found any usage of each function. If I use two testcases in the each with one succefull and one wrong paramateres, then tests will failed only if wrong test case was first.
Sorry, this is very hard for me to debug, especially since it is working on every system I have tried it on. The core babylon developers use different environments as well, and we have never experienced that.
Running npm run test:unit should use the local jest installation. Is it possible you have a global version of jest that is older?
I run npx jest -v and version of Jest is same as in the package.json .
And one interesting point - I wrote above:
Test Suites: 10 failed, 7 passed, 17 total
Tests: 35 passed, 35 total
Snapshots: 0 total
Time: 3.907 s, estimated 22 s
Ran all test suites.
And it was on the node version 14.17.0. Now I install npm 16.17.0 and npm run test:unit shows this:
Test Suites: 1 failed, 16 passed, 17 total
Tests: 53 passed, 53 total
Snapshots: 0 total
Time: 4.969 s, estimated 10 s
Ran all test suites.
Now failed just one test with:
FAIL unit packages/dev/core/test/unit/XR/webXRFeaturesManager.test.ts
â Test suite failed to run
The module '\\?\D:\OSPanel\domains\Babylon.js\node_modules\canvas\build\Release\canvas.node'
was compiled against a different Node.js version using
NODE_MODULE_VERSION 83. This version of Node.js requires
NODE_MODULE_VERSION 93. Please try re-compiling or re-installing
the module (for instance, using `npm rebuild` or `npm install`).

UPD. After this I reinstall node modules and all tests are passed!
