Test Directories

Directory	Runs on CI	Purpose
abort	No	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
fixtures		Test fixtures used in various tests throughout the test suite.
gc	No	Tests for garbage collection related functionality.
inspector	Yes	Tests for the V8 inspector integration.
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).
