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. |
