Trace a Test

Use the Trace test option to create a log of every system call made when a test is running. This feature logs the system calls using the standard UNIX command truss. The trace messages logged by this feature give you a powerful debugging tool when isolating the specific cause of an error.

From a TTY command line, you can use the UNIX truss(1) command on any test while running SunVTS. (See the truss(1) man page for more information.)

To Enable Tracing

1. Click Commands on the Menu bar and pull down to Trace test.

   The Trace Test window is displayed as shown in the figure below.

2. Choose one or more tests to be traced from the scrollable list of test names and then select Apply, or double-click a test name to enable tracing and close the window.

   When you select a test, system call tracing is enabled immediately. If the test is already running when you select it, tracing begins immediately and the trace test messages appear in the SunVTS console window.

3. Select File and click Apply to write the trace test messages to a file.

To Disable Tracing

1. Bring up the Trace Test window again, select the highlighted test name, and click Apply.

   This action removes the highlighting and disables tracing.
