| + <h1>Test suspend()/resume() issues</h1> |
| + |
| + <p> |
| + The functionality of suspend()/resume() can't be tested with an OfflineAudioContext, so they |
| + need to be tested manually here. |
| + </p> |
| + |
| + <p> |
| + Do the tests in the order given. |
| + </p> |
| + <h2>Test 1</h2> |
| + <p> |
| + Test for <a href="crbug.com/483002">issue 483002</a> |
| + </p> |
| + <p> |
| + Press the button to run the test. Each press should cause "suspended" and |
| + "running" to be printed out in the Results section below and in the console. |
| + </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: 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. |
| + </p> |
| + <button onclick="test2Start()">Test 2: Start Test</button> |
| + <button onclick="test2Run()">Test 2: Run Test </button> |
| + <button onclick="test2End()">Test 2: End Test </button> |
