Description

Earlier this year, a feature was added to the WPT CLI to support executing a new kind of test. Yesterday, the first of these tests were introduced into WPT. The addition of these tests uncovered an inconsistent behavior.

The "jsshell" version of these tests cannot be executed by any code available in WPT itself, so the WPT CLI ignores them during normal test execution. This means it does not attempt to run them, and it also does not include them in its various output logs. However, other features interact with the tests (e.g. --list-tests, --list-disabled, --list-test-groups, and --verify), but these do not ignore the "jsshell" versions.

This inconsistency may cause confusion for human operators, and it interferes with scripted applications of the WPT CLI (see https://github.com/web-platform-tests/results-collection/issues/590).

Research direction

Start by tracing how the WPT CLI handles "jsshell" tests during normal execution, then compare that behavior with --list-tests, --list-disabled, --list-test-groups, and --verify. Done means these features consistently include or ignore the tests according to the intended execution behavior, without confusing operators or scripted consumers.
