Paul Bouchon 1b2de5e052 module: fix --check on ambiguous ESM files
A `.js` file with no `"type"` in the nearest package.json has no format
of its own, and `defaultGetFormat()` reports it as null. `--check`
passed that null straight to `wrapSafe()`, which parses as CommonJS.
Module syntax makes that parse bail out early, so the file was reported
as valid and `--check` exited 0 even though it is not valid JavaScript
under either goal.

At load time the goal for such a file is decided by looking for module
syntax in the source. Decide it the same way here, so the file is
parsed as a module and its real syntax error is reported. Files whose
format is known are unaffected, as are ambiguous files without module
syntax, which are still parsed as CommonJS.

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.

Test Directories

Directory Runs on CI Purpose
abort Yes Tests that use --abort-on-uncaught-exception and other cases where we want to avoid generating a core file.
addons Yes Tests for addon functionality along with some tests that require an addon.
async-hooks 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.
es-module Yes Test ESM module loading.
fixtures N/A Test fixtures used in various tests throughout the test suite.
internet No Tests that make real outbound network connections.2
js-native-api Yes Tests for Node.js-agnostic Node-API functionality.
known_issues Yes Tests reproducing known issues within the system.3
message Yes Tests for messages that are output for various conditions
node-api Yes Tests for Node.js-specific Node-API functionality.
parallel Yes Various tests that are able to be run in parallel.
pseudo-tty Yes Tests that require stdin/stdout/stderr to be a TTY.
pummel No Various tests for various modules / system functionality operating under load.
sequential Yes Various tests that must not run in parallel.

  2. Tests for networking related modules may also be present in other directories, but those tests do not make outbound connections. ↩︎

  3. 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. ↩︎

  4. 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. ↩︎
