ESM resolution and loading is now always synchronous from a non-loader-hook thread. If no asynchrnous loader hooks are registered, the resolution/loading is entirely synchronous. If asynchronous loader hooks are registered, these would be synchronous on the non-loader-hook thread, and asynchronous on the loader hook thread. This avoids several races caused by async/sync loading sharing the same cache. In particular, asynchronous loader hooks now works with `require(esm)` - previously it tends to break due to races. In addition, when an asynchronous loader hook returns a promise that never settles, the main thread no longer silently exits with exit code 13, leaving the code below any module loading calls silently ignored without being executed. Instead, it now throws ERR_ASYNC_LOADER_REQUEST_NEVER_SETTLED which can be caught and handled by the main thread. If the module request comes from `import()`, the never-settling promise is now relayed to the result returned by `import()`. Drive-by: when annotating the error about importing undetectable named exports from CommonJS, it now no longer reload the source code of the CommonJS module, and instead reuses format information cached when the module was loaded for linking.

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.

Yes | Tests for async_hooks functionality. |
benchmark |
Yes | Test minimal functionality of benchmarks. |
cctest |
Yes | C++ tests that are run as part of the build process. |
code-cache |
No | Tests for a Node.js binary compiled with V8 code cache. |
common |
N/A | Common modules shared among many tests.1 |
doctool |
Yes | Tests for the documentation generator. |

-
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/v8_prof_processor.jsandlib/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. ↩︎
