| 17 <h1>Test suspend()/resume() issues</h1> |
| 18 |
| 19 <p> |
| 20 The functionality of suspend()/resume() can't be tested with an OfflineAud
ioContext, so they |
| 21 need to be tested manually here. |
| 22 </p> |
| 23 |
| 24 <p> |
| 25 Do the tests in the order given. |
| 26 </p> |
| 27 <h2>Test 1</h2> |
| 28 <p> |
| 29 Test for <a href="crbug.com/483002">issue 483002</a> |
| 30 </p> |
| 31 <p> |
| 32 Press the button to run the test. Each press should cause "suspended" and |
| 33 "running" to be printed out in the Results section below and in the consol
e. |
| 34 </p> |
| 35 <button onclick="test1Start()">Test 1: Start Test</button> |
| 36 <button onclick="test1Run()">Test 1: Run Test</button> |
| 37 <button onclick="test1End()">Test 1: End Test</button> |
| 38 <br></br> |
| 39 |
| 40 <h2>Test 2</h2> |
| 41 <p> |
| 42 Test for <a href="crbug.com/483269">issue 483269</a> |
| 43 </p> |
| 44 <p> |
| 45 Perform the following steps |
| 46 <ol> |
| 47 <li>Start Test: you should hear a tone. Wait a little bit before procee
ding. |
| 48 </li> |
| 49 <li>Run Test: This calls suspend()/resume() multiple times. The tone sh
ould stop |
| 50 momentarily, but restart very quickly. You should still hear the tone. |
| 51 </li> |
| 52 <li>End Test: Stops the tone. |
| 53 </li> |
| 54 </ol> |
| 55 </p> |
| 56 <p> |
| 57 If you do not hear a tone after running the test (but before ending), the
test has failed. |
