This is similar to the `queryObjects()` console API provided by the Chromium DevTools console. It can be used to search for objects that have the matching constructor on its prototype chain in the entire heap, which can be useful for memory leak regression tests. To avoid surprising results, users should avoid using this API on constructors whose implementation they don't control, or on constructors that can be invoked by other parties in the application. To avoid accidental leaks, this API does not return raw references to the objects found. By default, it returns the count of the objects found. If `options.format` is `'summary'`, it returns an array containing brief string representations for each object. The visibility provided in this API is similar to what the heap snapshot provides, while users can save the cost of serialization and parsing and directly filer the target objects during the search. We have been using this API internally for the test suite, which has been more stable than any other leak regression testing strategies in the CI. With a public implementation we can now use the public API instead.

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 situations where we want to test something but 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 |
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 Node-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 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. |
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. |
