Media/WebRTC/Testing

WebRTC Test System

We currently test WebRTC with two sets of tests:

• Standalone C++ unit and system tests.
• Full system mochitests.

C++ Unit Tests

The WebRTC code has extensive C++ unit and system tests based on the [| Google Test] framework. These tests live in two locations:

• media/mtransport — the mtransport generic transport subsystem and associated utilities
• media/webrtc/signaling/test — the signaling system and the media handling system

As usual, you can run them individually by doing:

  make -C <directory>

Alternately, you can run a single C++ unit test by name, e.g.,

  media/mtransport/test/ice_unittest

Tinderbox runs all the tests in a given directory but for a variety of reasons some of the tests aren't run on Tinderbox. This is controlled by requiring certain environment variables to be set.

A number of tests have been disabled on Tinderbox because they either take a long time or have excessive oranges. To enable these, set:

   MOZ_WEBRTC_TESTS=1

Additionally, the TURN tests require you to specify a TURN server. However, we don't provide one for Tinderbox because we don't want to operate a public server and releng hasn't set one up in the test environment yet. [[ https://bugzilla.mozilla.org/show_bug.cgi?id=865296 Bug 865296]]

If you have a TURN server, you can point the tests at it by setting:

   TURN_SERVER_ADDRESS
   TURN_SERVER_USER
   TURN_SERVER_PASSWORD
