With node-jest now in the NEW queue, I have started working on this here: https://salsa.debian.org/js-team/node-yarnpkg/-/tree/jest
I have built jest from https://salsa.debian.org/js-team/node-jest assuming commit b9255f45c22c030b863e7d42aaf78c207db43478 will be tagged as 24.9.0+ds-2 (although that is not in NEW queue): git checkout b9255f45c22c030b863e7d42aaf78c207db43478 git switch -c debian/24.9.0+ds-2 gbp buildpackage -uc -us --git-ignore-branch I need to side-load these packages to /usr/share/nodejs to make jest start: import-local realpath-native jest-snapshot-serializer-raw sane react-is natural-compare p-each-series throat Now the test suite starts, and all 91 tests fail. I need to also side-load: string-length fast-json-stable-stringify source-map-support not sure if these are jest run-time dependencies or yarnpkg test-time dependencies. Now all the tests fail because: Cannot find module 'source-map-support' from 'source-map-support.js' To fix this, I upgrade source-map-support to 0.5.19; now I get: Cannot find module 'chalk' from 'Env.js' this comes from /usr/share/nodejs/jest-jasmine2/build/jasmine/Env.js which is compiled from node-jest/packages/jest-jasmine2/src/jasmine/Env.ts. But node-chalk is installed: nodejs > chalk = require('chalk'); { [Chalk] constructor: [Function: Chalk], supportsColor: { level: 2, hasBasic: true, has256: true, has16m: false }, default: [Circular] } > ^d Clearly the jest command is broken. I suggest to enable the jest self-test suite in node-jest. I tried running "jest" in node-jest source tree (after side-loading the 8 packages above), I get: ● Validation Error: Test environment ./packages/jest-environment-node cannot be found. Make sure the testEnvironment configuration option points to an existing node module. Configuration Documentation: https://jestjs.io/docs/configuration.html Although ./packages/jest-environment-node exists (?) I tried to specify the testEnvironment from the command line: jest --env=node and with that I get: ● Validation Error: Module <rootDir>/packages/pretty-format/build/plugins/ConvertAnsi.js in the snapshotSerializers option was not found. <rootDir> is: /root/node-jest Configuration Documentation: https://jestjs.io/docs/configuration.html Also note that the command: jest --init requires side-loading prompts module. For my own record, I reset all the changes to my test machine with: apt remove jest apt autoremove cd /usr/share/nodejs rm import-local realpath-native jest-snapshot-serializer-raw sane react-is natural-compare p-each-series throat string-length fast-json-stable-stringify source-map-support prompts mv source-map-support.old/ source-map-support Paolo
