Automation of the Spirenttestcenter tester

Spirenttestcenter, the United States think Bollen Company's network testing instruments, covering the Ethernet L2~L7 layer, the use of the most powerful instrument.

Automated test scenarios for 1.SpirentTestcenter

Test the at frame on the PC---->TCL Driver Library SIG_TEQ_STC.TCL (load Spirenttestcenter Library)-----(Ethernet cable)----->STC Chassis

STC's Chassis internal command is also TCL format, but there is a disadvantage in debugging, script execution effect can not be immediately reflected in the Spirent testcenter application Client interface, observation results.

2.SpirentTestcenter TCL API Organization structure

Spirent Testcenter All of the features available on the GUI have a corresponding API interface, its API organization is object-oriented, and provides support for multiple languages such as Tcl Java Perl Ruby C + +.

3.Spirent testcenter TCL API approximate format

The STC API uses a series of command/function to manipulate object, which is the chassis object handle generated internally by the handle, which exists throughout the process.

Command format:

functionname Objecttype/objecthandle/ddnpath attributename (AttributeName must start with "-") Attrnamevalue (attribute name value)/ Danpath [Value]/relationreference

Eg: (above three cases)

stc::create Project

Stc::get $project _handle

Stc::create project.port/stc::get $project _handle. Port

Stc::get $port-location/stc::get $port-active-location

Stc::config $port-active false-location "//10.1.1.1/1/1"

Stc::create $streamblock-under $port-frameconfig ""-ethernet. Ethernetii.ethertype 880b/stc::config $project-port.active false/stc::get $project-port.active

Stc::get $port 1-children (children is a pair of related object properties)

There are also some commands that are directly followed by specific values, such as:

stc::connect//172.168.1.1 stc::reserve//172.168.1.1/1/1 stc::sleep 5

How path is represented:

direct-descendant Notation (DDN) direct descendant symbol

descendant-attribute Notation (DAN)

indexed Notation (DDN and DAN)

eg

Stc::config $project. Port-active false-location "//10.1.1.1/1/1"

Stc::config $project-port (1). Active False-port (2). Active false

Set enabled [Stc::get $port 1-streamblock (2). Enablecontrolplane]

The basic commands are stc::xxx, where STC:: represents the STC namespace to differentiate acknowledgment functions, and function names are lowercase, object names and property names are not case-sensitive

The usual "XXX" has the following:

Apply all configuration-related command stc::apply

Config

Create

Delete

Disconnect

4. Some STC at time considerations

(1) STC's client Spirent Testcenter application after the installation is complete, there is a. TCL library file that defines the STC chassis internal TCL command:

c:/program files/spirent communications/spirent testcenter 3.55/spirent testcenter Application/ SPIRENTTESTCENTER.TCL.

This library file needs to be written to the PKGINDEX.TCL in the TCL package directory so that the TCL library can be found and loaded in the Sig_teq_stc.tcl file by "packages require Spirenttestcenter"

(2) Spirent testcenter application do not have their own TCL interrupt, so the operation of STC can use any TCL interrupt, as long as the use of the library files are loaded can

This article is simply an introduction to the Spirent Testcenter Automation principle, the detailed Spirenttestcenter TCL API can be found in the specific API official documentation.
