iTest: How to perform negative testing on Calix devices.

Environment/Versions

Spirent iTest

Answer

 

While performing negative testing for few routers/switches (e.g., Calix switch) if we give any wrong command it will throw a syntax error and prompt you to edit or delete the same command. Otherwise remaining steps will append with that syntax error step.

Here is the example:

Here control-vlan 0 is not valid command so it throws syntax error and it expects backspace command to hit and move forward. Here it’s not happened so remaining all commands are appended to the existing command.

Grand# configure

Grand(config)# g8032-ring 1

Grand(g8032-ring 1)# control-vlan 0

Syntax error: Illegal parameter

Grand(g8032-ring 1)# control-vlan 0end

Syntax error: Illegal parameter

Grand(g8032-ring 1)# control-vlan 0endshowg8032-ring1

Syntax error: Illegal parameter

Grand(g8032-ring 1)# control-vlan 0endshowg8032-ring1config

Syntax error: Illegal parameter

Grand(g8032-ring 1)# control-vlan 0endshowg8032-ring1configg8032-ring1

Syntax error: Illegal parameter

Grand(g8032-ring 1)# control-vlan 0endshowg8032-ring1configg8032-ring1control-vlan4096

Syntax error: Illegal parameter

Grand(g8032-ring 1)# control-vlan 0endshowg8032-ring1configg8032-ring1control-vlan4096end

Syntax error: Illegal parameter

Grand(g8032-ring 1)# control-vlan 0endshowg8032-ring1configg8032-ring1control-vlan4096end

In this scenario it’s very difficult to perform negative testing through iTest because prompt issue hits for each and every step.

Solution:

To overcome this issue we need to add a new step [char Ctrl-u] which will clear the pervious command. So that it’s easy to perform both positive and negative testing.
