Remove the unnecessary microTasksTickObject for scheduling microtasks and instead use TickInfo to keep track of whether promise rejections exist that need to be emitted. Consequently allow the microtasks to execute on average fewer times, in more predictable manner than previously. Simplify unhandled & handled rejection tracking to do more in C++ to avoid needing to expose additional info in JS. When new unhandledRejections are emitted within an unhandledRejection handler, allow the event loop to proceed first instead. This means that if the end-user code handles all promise rejections on nextTick, rejections within unhandledRejection now won't spiral into an infinite loop.

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.
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 to function properly. |
| cctest | Yes | C++ test that is run as part of the build process. |
| common | Common modules shared among many tests. Documentation | |
| es-module | Yes | Test ESM module loading. |
| fixtures | Test fixtures used in various tests throughout the test suite. | |
| gc | No | Tests for garbage collection related functionality. |
| internet | No | Tests that make real outbound connections (mainly networking related modules). Tests for networking related modules may also be present in other directories, but those tests do not make outbound connections. |
| known_issues | Yes | Tests reproducing known issues within the system. All tests inside of this directory are expected to fail consistently. 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.) |
| 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 are run sequentially. |
| 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. |
| timers | No | Tests for timing utilities (setTimeout and setInterval). |
When a new test directory is added, make sure to update the CI_JS_SUITES
variable in the Makefile and the js_test_suites variable in
vcbuild.bat.
