Description

Name: iaR10016			Date: 11/01/2002


Filed By       : J2SE-SQA [###@###.###
JDK            : JDK1.4.2-b04
JCK            : RegTest-test
Platform[s]    : RedHat Linux 7.3, Windows 98, Solaris Sparc, Solaris x86
                 (the tests fail on any computer without a sound device)
Falling tests  : javax/sound/sampled/Clip/Duration/ClipDuration.java
                 javax/sound/sampled/Clip/Endpoint/ClipSetEndPoint.java
                 javax/sound/sampled/Controls/FloatControl/FloatControlBug.java
                 javax/sound/sampled/Controls/ReverbControl/SimpleMidiPlayer.java

It would be better if these tests performed any analysis whether a sound device existed on the computer.
Please, see bug 4742021 for more details.

How to reproduce:
=================
Run the following script (you may need to change its TESTJAVA and TEST_BASE variables)
on the machine which does not have a sound device

--- script start ---
#!/bin/sh
TESTJAVA="/net/jdk/export/disk8/local.java/jdk1.4.2/linux-i386"
TEST_BASE="/java/re/jdk/1.4.2/latest/ws/j2se/"
TEST_PATH="$TEST_BASE/test/javax/sound/sampled/Clip/Duration"
TEST_NAME="ClipDuration"
$TESTJAVA/bin/javac -d . $TEST_PATH/$TEST_NAME.java
$TESTJAVA/bin/java -showversion $TEST_NAME
--- script end ---

SUGGESTED FIX add this code to all regression tests that use a soundcard: in main(): if (!isSoundcardInstalled()) { return; } add this method: /** * Returns true if at least one soundcard is correctly installed * on the system. * A soundcard is installed if a TargetDataLine exists * and it has formats. We cannot use the existence of * SourceDataLines, because the Java Sound Engine always reports * an available SourceDataLine, even if none is actually * accessible */ public static boolean isSoundcardInstalled() { boolean result = false; try { Mixer.Info[] mixers = AudioSystem.getMixerInfo(); for (int i=0; i<mixers.length; i++) { try { Mixer mixer = AudioSystem.getMixer(mixers[i]); Line.Info[] infos = mixer.getTargetLineInfo(); for (int ii = 0; ii<infos.length; ii++) { if (infos[ii] instanceof DataLine.Info) { DataLine.Info info = (DataLine.Info) infos[ii]; result = (info.getFormats().length > 0); if (result) break; } } } catch (Exception e1) { System.err.println(e1); } if (result) break; } } catch (Exception e2) { System.err.println(e2); } if (!result) { System.err.println("Soundcard does not exist or sound drivers not installed!"); System.err.println("This test requires sound drivers for execution."); } return result; }

PUBLIC COMMENTS Regression tests should not fail if soundcard is not installed.
10-06-2004
EVALUATION ###@###.### 2002-11-22 As of discussion with SQA, reg tests should not fail if the hardware is not correctly set up. The tests need to be fixed so that they "pass" on machines without soundcard.
