| <h1>Test suspend()/resume()</h1> |
| |
| <p> |
| The functionality of suspend()/resume() can't currently be tested with an OfflineAudioContext, |
| so they need to be tested manually here. |
| </p> |
| <p> |
| You may want to open up a console window to see the messages, in addition to viewing the |
| messages in the Results area below. |
| </p> |
| |
| <h2>Test 1</h2> |
| <p> |
| Test for <a href="crbug.com/483002">issue 483002</a> |
| </p> |
| <p> |
| Perform the following steps |
| <ol> |
| <li> |
| Start Test: you should hear a tone. |
| </li> |
| <li> |
| Run Test: This runs the test. You may press this multiple times. Each press should cause |
| "suspended" and "running" to be printed out in the Results section below and in the |
| console. |
| </li> |
| <li> |
| End Test: Press this to end the test and stop the audio. |
| </li> |
| </ol> |
| </p> |
| <button onclick="test1Start()">Test 1: Start Test</button> |
| <button onclick="test1Run()">Test 1: Run Test</button> |
| <button onclick="test1End()">Test 1: End Test</button> |
| <br></br> |
| |
| <h2>Test 2</h2> |
| <p> |
| Test for <a href="crbug.com/483269">issue 483269</a> |
| </p> |
| <p> |
| Perform the following steps |
| <ol> |
| <li> |
| Start Test: you should hear a tone. Wait a little bit before proceeding. |
| </li> |
| <li> |
| Run Test: You may press this multiple times. This calls suspend()/resume() multiple times. |
| The tone should stop momentarily, but restart very quickly. You should still hear the |
| tone. |
| </li> |
| <li> |
| End Test: Stops the tone. |
| </li> |
| </ol> |
| </p> |
| <p> |
| If you do not hear a tone after running the test (but before ending), the test has failed. |
