Howto: Running the tests and not seeing the output

[Largo]

I was struggling in how to get the tests to run. I followed the contribution document.

I ran: rake npm:ruby-head-wasm-wasi:check

rake npm:ruby-head-wasm-wasi:check                          (base) 
npm test

> @ruby/[email protected] test
> RUBY_NPM_PACKAGE_ROOT=../ruby-head-wasm-wasi npm -C ../ruby-wasm-wasi run test:run:all


> @ruby/[email protected] test:run:all
> npm run test:run && ENABLE_COMPONENT_TESTS=1 npm run test:run


> @ruby/[email protected] test:run
> npm run test:unit && npm run test:vitest -- --run && npm run test:e2e


> @ruby/[email protected] test:unit
> ./tools/run-test-unit.mjs

Turns out that if you go directly into the npm package ruby.wasm/packages/npm-packages/ruby-head-wasm-wasi
and run npm test you see the errors:

Which Node.js version are you using? Due to Node.js issue, the test suite #314, Node.js 20 and later causes segmentation fault while running tests, so please ensure that you are using Node.js 18
