// Test that if a feature is 'experimental' then we must be in a nightly build,
// and if a feature is 'released' then it must be enabled on release and beta.
//
// An experimental feature is allowed to be disabled by platform/feature flags,
// we only require that it can never be enabled on release/beta builds.
//
// A released feature is allowed to be disabled on nightly. This is useful for
// if we're testing out a new compiler/configuration where a released feature
// is not supported yet. We only require that on release/beta, the feature must
// be enabled.
//
// As features are advanced, this test must be manually updated.
//
// NOTE0: The |jit-test| directive must be updated with all opt-in shell flags
// for experimental features for this to work correctly.
// NOTE1: This test relies on feature functions accurately guarding use of the
// feature to work correctly. All features should have a 'disabled.js'
// test to verify this. Basic testing for this is included with each
// feature in this test for sanity.
// NOTE2: Keep this file in sync with:
// `dom/worklet/tests/worklet_audioWorklet_WASM_features.js`.
