From 05915fb47a44e73dc62675da524ff7b178011910 Mon Sep 17 00:00:00 2001 From: Timo Date: Thu, 12 Dec 2024 15:58:10 +0100 Subject: [PATCH] remove all legacy call related code and adjust tests. We actually had a bit of tests just for legacy and not for session events. All those tests got ported over so we do not remove any tests. --- spec/unit/matrixrtc/CallMembership.spec.ts | 115 ++------ spec/unit/matrixrtc/MatrixRTCSession.spec.ts | 223 ++++++---------- .../matrixrtc/MatrixRTCSessionManager.spec.ts | 24 +- spec/unit/matrixrtc/mocks.ts | 73 +++-- src/@types/event.ts | 11 +- src/matrixrtc/CallMembership.ts | 129 ++------- src/matrixrtc/MatrixRTCSession.ts | 251 +++--------------- src/webrtc/groupCall.ts | 6 - 8 files changed, 219 insertions(+), 613 deletions(-) diff --git a/spec/unit/matrixrtc/CallMembership.spec.ts b/spec/unit/matrixrtc/CallMembership.spec.ts index c3281b96ac3..fb2df400b92 100644 --- a/spec/unit/matrixrtc/CallMembership.spec.ts +++ b/spec/unit/matrixrtc/CallMembership.spec.ts @@ -15,7 +15,8 @@ limitations under the License. */ import { MatrixEvent } from "../../../src";
