| This is a testharness.js-based test. |
| PASS insertDTMF() with default duration and intertoneGap should fire tonechange events at the expected time |
| PASS insertDTMF() with explicit duration and intertoneGap should fire tonechange events at the expected time |
| PASS insertDTMF('') should not fire any tonechange event, including for '' tone |
| PASS insertDTMF() with duration less than 40 should be clamped to 40 |
| PASS insertDTMF() with interToneGap less than 30 should be clamped to 30 |
| PASS insertDTMF with comma should delay next tonechange event for a constant 2000ms |
| PASS insertDTMF() with transceiver stopped in the middle should stop future tonechange events from firing |
| PASS Calling insertDTMF() in the middle of tonechange events should cause future tonechanges to be updated to new tones |
| PASS Calling insertDTMF() multiple times in the middle of tonechange events should cause future tonechanges to be updated the last provided tones |
| PASS Calling insertDTMF('') in the middle of tonechange events should stop future tonechange events from firing |
| PASS Setting transceiver.currentDirection to recvonly in the middle of tonechange events should stop future tonechange events from firing |
| PASS Tone change event constructor works |
| PASS Tone change event with unexpected name should not crash |
| FAIL Tone change event init optional parameters Failed to construct 'RTCDTMFToneChangeEvent': 2 arguments required, but only 1 present. |
| Harness: the test ran to completion. |
