Running a Test From the Command Line

In some cases it may be more convenient to run a single SunVTS test from the command line. The test runs without the SunVTS kernel (vtsk). All events and errors are sent to stdout or stderr, and are not logged in the log files.

There are two directories where tests reside:

Use the test pathname based on the type (32-bit or 64-bit) of operating system that is running. The SUNWvtsx package must be installed for 64-bit SunVTS support. If a test is not present in this directory, then it may only be available as a 32-bit test.

When you run a test from the command line, you must specify all test options in the form of command-line arguments.

There are two types of command-line arguments:

The standard syntax for command-line execution is:

testname [-scruvdtelnf] [-p number] [-i number] [-w number] [-o test_specific_arguments]

The standard command-line argument usage for all SunVTS tests is:

Table 4-11 Standard Command-line Arguments
 Argument Definition
 -sRun a test as though it were invoked from the SunVTS kernel (vtsk). This causes the test to send output to an RPC port that the SunVTS kernel is using. The default is to send the output to stdout or stderr
 -c Enables a core image of the test process to be created in the current working directory upon receipt of certain signals, otherwise those signals are caught and handled to prevent a core from being generated. The default is to disable the creation of a core image
 -r Enables run on error so that when an error occurs, the test continues with the next test sequence instead of exiting. The default is false
 -u  Displays command line usage information
 -v Runs the test in Verbose mode and displays messages with more detailed information about the testing process. The default is false
 -d Runs the test in debug mode and displays messages to help programmers debug their test code. The default is false
 -t Runs the test in test function Trace mode and displays messages that track function calls and sequences currently in use by the test code. The default is false
 -e Runs the test in Stress Mode by increasing the system load. The default is false
 -l Runs the test in Online Functional mode. This is the same mode that tests run in when executed through SyMON. It is a non-intrusive version that will not significantly affect other applications. See the note below. The default is true
 -n Runs the test in Connection Mode. See the note below.The default is false
 -f Runs the test in full Functional test mode. This mode assumes that the test has complete control of the device under test. See the note below. The default is false
 -i number Defines the number of instances for scalable tests
 -p number Defines the number of passes
 -w number For scalable tests, defines to which instance the test is assigned
 -o Used to indicate that the options and arguments that follow are test specific. Note - separate each test specific argument by commas, with no space after each comma

Note -

If you choose to specify a test mode with the l, n, or f option, specify only one option at a time because only one test mode can be selected at a time.

Command Line Test Example

The following example shows the audiotest running from the command line with a combination of standard command-line arguments (-vf) and test specific options (-o M,X) 

# /opt/SUNWvts/bin/audiotest -vf -p1 -o M,X
"Test Options: M,X"
"audiotest: Started."
"rec_play: read/write 8000 bytes"
"Audio music test"
"Audio crystal test, rate = 8000 Hz, time = 998289 usecs"
"Audio crystal test, rate = 48000 Hz, time = 999974 usecs"
"Starting loopback test: internal_codec"
"Play Gain = 230, Record Gain = 0"
"Sample Rate =  8000 Hz, Freq = 1000 Hz  MONO u-law"
"	snr = 40.59 dB"
"Sample Rate =  8000 Hz, Freq = 1000 Hz  MONO a-law"
"	snr = 44.79 dB"
"Sample Rate =  8000 Hz, left = 1000 Hz,  right = 1000
Hz"
"left  : snr = 68.25 dB, gain = -4.99 dB"
"right : snr = 68.32 dB, gain = -5.07 dB"
"audiotest: Stopped successfully."
