Runs on CI
No

addons

Tests for addon functionality along with some tests that require an addon to function properly.

Runs on CI
Yes

cctest

C++ test that is run as part of the build process.

Runs on CI
Yes

debugger

Tests for debugger functionality.

Runs on CI
No

disabled

Tests that have been disabled from running for various reasons.

Runs on CI
No

fixtures

Test fixtures used in various tests throughout the test suite.

gc

Tests for garbage collection related functionality.

Runs on CI
No

inspector

Tests for the V8 inspector integration.

Runs on CI
Yes

internet

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.

Runs on CI
No

known_issues

Tests reproducing known issues within the system.

Runs on CI
No

message

Tests for messages that are output for various conditions (console.log, error messages etc.)

Runs on CI
Yes

parallel

Various tests that are able to be run in parallel.

Runs on CI
Yes

pummel

Various tests for various modules / system functionality operating under load.

Runs on CI
No

sequential

Various tests that are run sequentially.

Runs on CI
Yes

testpy

Test configuration utility used by various test suites.

tick-processor

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.

Runs on CI
