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 for when the --abort-on-uncaught-exception flag is used.
addons	Yes	Tests for addon functionality along with some tests that require an addon.
async-hooks	Yes	Tests for async_hooks functionality.
benchmark	No	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		Common modules shared among many tests. Documentation
doctool	Yes	Tests for the documentation generator.
es-module	Yes	Test ESM module loading.
fixtures		Test fixtures used in various tests throughout the test suite.
internet	No	Tests that make real outbound network connections. Tests for networking related modules may also be present in other directories, but those tests do not make outbound connections.
js-native-api	Yes	Tests for Node.js-agnostic n-api functionality.
known_issues	Yes	Tests reproducing known issues within the system. 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.
message	Yes	Tests for messages that are output for various conditions (console.log, error messages etc.)
node-api	Yes	Tests for Node.js-specific n-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.
testpy		Test configuration utility used by various test suites.
tick-processor	No	Tests for the V8 tick processor integration. The tests are for the logic in lib/internal/v8_prof_processor.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.
v8-updates	No	Tests for V8 performance integration.
