tone-generator

Description

This is a test plan for tone-generator, a telephony session daemon used by Ubuntu Touch. It does not cover scenarios and/or test cases for tone-generator installed on the desktop.

tone-generator is a simple daemon which provides a basic DBus interface on the session bus which allows clients to trigger local playback of telephony-related tones, primarily DTMF ( eg. dialer keypad tones ).

Setup

Install the tone-generator-scripts package which bundles some scripts which make tesing easier.

Test Cases

1. Basic DTMF Playback

Purpose

Verify that tone-generator can trigger local playback of DTMF tones.

Steps:

As phablet user: 

% /usr/share/tone-generator/test-dtmf <keypad number>

tone-number is a keypad number from 0-9.

Verification:

  • Verify that tone is played for 3 seconds and then stops ( compare to another phone )

2. DTMF Playback during a Call

Purpose

Verify that tone-generator obeys system audio routing.

Steps:

  • Dial and connect a cellular voice call
  • Play a DTMF tone, via the 'test-dtmf' script as above
  • Enable the loudspeaker
  • Play a DTMF tone, via the 'test-dtmf' script as above
  • End the call

Verification:

  • Verify that the first DTMF tone is played in the earpiece, and the second in the loudspeaker.

3. Tone Generation and System Sound Levels

Purpose

Verify that tone-generator obeys system sound levels.

Steps:

  • Open System Settings / Sound
  • Set volume slider to zero, medium, and full level
  • For each volume level, play a DTMF tone, via the 'test-dtmf' script as above

Verification:

  • Verify that the output level is appropriate in all three cases.

4. Basic Signal Playback

Purpose

Verify that tone-generator can trigger local playback of telephony signal sounds.

Steps:

As phablet user: 

% /usr/share/tone-generator/scripts/test-signal 72

Value 72 represents phone line busy (other values in the script's help text).

Verification:

  • Verify that a series of several beeps (representing a busy phone line) is played.

Automation Status

Automation of the tone-generator testing is currently blocked pending improvements to the emulator's telephony support.
