test(e2e): add Convert and Stream view end-to-end tests (#55)
* test(e2e): add Convert and Stream view end-to-end tests Add Playwright e2e tests covering: - Convert view with Audio Mixing pipeline (API + UI tests) - Stream view with MoQ session lifecycle and connection tests Infrastructure changes: - Add data-testid to ConvertView and StreamView for test selectors - Configure fake audio device and microphone permissions in Playwright - Pass MoQ gateway URL to e2e server harness Signed-off-by: StreamKit Devin <devin@streamkit.dev> Co-Authored-By: Claudio Costa <devin@streamkit.dev> * fix(e2e): resolve test failures in convert and stream specs - API test: use browser-side fetch with early abort to avoid timeout from streaming response body (mixing pipeline streams in real-time) - Session lifecycle test: filter QUIC/TLS/cert errors from auto-connect - MoQ connection test: handle auto-connect behavior, gracefully skip when WebTransport connection cannot be established - Remove unused 'request' import from convert.spec.ts Signed-off-by: StreamKit Devin <devin@streamkit.dev> Co-Authored-By: Claudio Costa <devin@streamkit.dev> * fix(e2e): use .first() for Disconnect button to avoid strict mode violation When MoQ is connected, two Disconnect buttons are rendered (one in SessionPanel, one in Connection & Controls). Use .first() to resolve the strict mode ambiguity. Signed-off-by: StreamKit Devin <devin@streamkit.dev> Co-Authored-By: Claudio Costa <devin@streamkit.dev> * refactor(e2e): shared console error helper, audio playback verification, robust MoQ error filtering - Extract console error collection into shared test-helpers.ts with createConsoleErrorCollector() and configurable benign pattern filtering - Replace broad BENIGN_PATTERNS with specific MOQ_BENIGN_PATTERNS (QUIC_TLS_CERTIFICATE_UNKNOWN instead of ERR_QUIC_PROTOCOL_ERROR) - Add verifyAudioPlayback() helper to check audio element has loaded and started playback in convert tests - Add installAudioContextTracker() / verifyAudioContextActive() to verify Hang is receiving/decoding/playing audio via Web Audio API - Fix sessionId extraction from UI so afterEach cleanup actually works - Clear sessionId after successful session destruction Signed-off-by: StreamKit Devin <devin@streamkit.dev> Co-Authored-By: Claudio Costa <devin@streamkit.dev> * style(e2e): fix prettier formatting to match CI config Signed-off-by: StreamKit Devin <devin@streamkit.dev> Co-Authored-By: Claudio Costa <devin@streamkit.dev> * fix(e2e): stop console error collection before disconnect/destroy phase WebTransport teardown emits benign 'The session is closed' errors during disconnect. Assert and stop the collector before the disconnect/destroy phase so shutdown noise does not cause false failures. Signed-off-by: StreamKit Devin <devin@streamkit.dev> Co-Authored-By: Claudio Costa <devin@streamkit.dev> * docs(e2e): add documentation comments to helpers and tricky logic Signed-off-by: StreamKit Devin <devin@streamkit.dev> Co-Authored-By: Claudio Costa <devin@streamkit.dev> --------- Signed-off-by: StreamKit Devin <devin@streamkit.dev> Co-authored-by: StreamKit Devin <devin@streamkit.dev>
