Node.js Core Tests

This directory contains code and data used to test the Node.js implementation.

For a detailed guide on how to write tests in this directory, see the guide on writing tests.

On how to run tests in this directory, see the contributing guide.

For the tests to run on Windows, be sure to clone Node.js source code with the autocrlf git config flag set to true.

Documentation ↩
Tests for networking related modules may also be present in other directories, but those tests do not make outbound connections. ↩
All tests inside of this directory are expected to fail. If a test doesn't fail on certain platforms, those should be skipped via known_issues.status. ↩
The tests are for the logic in lib/internal/main/prof_process.js and lib/internal/v8_prof_polyfill.js. The tests confirm that the profile processor packages the correct set of scripts from V8 and introduces the correct platform specific logic. ↩
