| 17 <h1>Test suspend()/resume()</h1> |
| 18 |
| 19 <p> |
| 20 The functionality of suspend()/resume() can't currently be tested with an
OfflineAudioContext, |
| 21 so they need to be tested manually here. |
| 22 </p> |
| 23 <p> |
| 24 You may want to open up a console window to see the messages, in addition
to viewing the |
| 25 messages in the Results area below. |

| 28 <h2>Test 1</h2> |
| 29 <p> |
| 30 Test for <a href="crbug.com/483002">issue 483002</a> |
| 31 </p> |
| 32 <p> |
| 33 Perform the following steps |
| 34 <ol> |
| 35 <li> |
| 36 Start Test: you should hear a tone. |
| 37 </li> |
| 38 <li> |
| 39 Run Test: This runs the test. You may press this multiple times. Eac
h press should cause |
| 40 "suspended" and "running" to be printed out in the Results section bel
ow and in the |
| 41 console. |
| 42 </li> |
| 43 <li> |
| 44 End Test: Press this to end the test and stop the audio. |
| 45 </li> |
| 46 </ol> |
| 47 </p> |
| 48 <button onclick="test1Start()">Test 1: Start Test</button> |
| 49 <button onclick="test1Run()">Test 1: Run Test</button> |
| 50 <button onclick="test1End()">Test 1: End Test</button> |
| 51 <br></br> |
| 52 |
| 53 <h2>Test 2</h2> |
| 54 <p> |
| 55 Test for <a href="crbug.com/483269">issue 483269</a> |
| 56 </p> |
| 57 <p> |
| 58 Perform the following steps |
| 59 <ol> |
| 60 <li> |
| 61 Start Test: you should hear a tone. Wait a little bit before proceedi
ng. |
| 62 </li> |
| 63 <li> |
| 64 Run Test: You may press this multiple times. This calls suspend()/resu
me() multiple times. |
| 65 The tone should stop momentarily, but restart very quickly. You should
still hear the |
| 66 tone. |
| 67 </li> |
| 68 <li> |
| 69 End Test: Stops the tone. |
| 70 </li> |
| 71 </ol> |
| 72 </p> |
| 73 <p> |
| 74 If you do not hear a tone after running the test (but before ending), the
test has failed. |
