Problems with WCF Windows Web Services over nettcp bindings with callbacks in LR 12.02 and 12.50

I'm hitting a nettcp based WCF Service using LR VuGen 12.02 and Web Services protocol by importing the WSDL of the Service.

After composing a request and trying to send it, I'm getting the following error. which actually works fine from the WPF Client but fails from the LR VuGen Script

    Action.c(16): Error:The socket connection was aborted. This could be caused by an error processing your message or a receive timeout being exceeded by the remote host, or an underlying network resource issue. Local socket timeout was '00:59:59.9949990'. 
Error: An existing connection was forcibly closed by the remote host

I have tried out many suggestions relevant but with no luck For your reference: Increasing Timeouts and maxItemsInObjectGraph and many more such posts on StackOverflow such as Socket Connection Aborted-StackOverflow post

 

I have posted this on StackOverflow and James Pulley replied back but I'm not able to build a custom solution using Visual Studio as it is very complex

Can you please let me know if LR VuGen 12.02 is compatible with nettcp binding and callbacks and if yes how to fix the issue

 

This is how I configured the Security settings based on the WSDL Description

Create Dynamic Request in Load Runner

October 9, 2015, 8:50 am

Hi all,

 

We are in need to develop a load runner script that dynamically create request based in a initial request.

 

By example, there is an initial request which brings some data from the web server and we need to use the content of that response to dynamically create multiple request with different body.

 

In more detail the example will be, the initial request will bring a list of material for instance 10 and the client parse the list and it will trigger 10 request one for each of the materials retrieved from the initial request, which part of the body of this request will contain the material number to retrieve the data from the backend

 

If the list of materials changes from the initial request the number of request will change.

 

The web application handle this using JS and we need to simulate the behavior in load runner.

 

If somebody can provide me some pointers, it will be great.

 

Thanks in avdance,

TruClient Business Process Report

Hello all,

 

I have two questions to the Business Process Report with the TruClient Script:

 

1. Is there a way to rename the "truclient_step"?

___

By Default:

 

4.2 Step: truclient_step

User Operations:

  • '2'.

Should look something like this:

 

4.2 Step: Navigate to 'https://www.google.com'

User Operations:

  • '2'.

 

___

I could do that by hand, but that is not what i want to do everytime.

 

2. Can you customize the Business Process Report , so it Contains the Result Viewer results ? Passed / Failed for each step?

 

Kind regards

Using regex in web_reg_save_param boundaries

Hi all,

 

I am trying to write a script which will pick up a dynamic value from a drop down menu and submit it to go to the next page. The HTTP response looks like this:

 

\t\t\t\t\t<option value="Rose taupe" id="WD26"class="WD26">Rose taupe</option>\n

\t\t\t\t\t<option value="Myrtle" id="WD20"class="WD20">Myrtle</option>\n

\t\t\t\t\t<option value="Deep carmine pink" id="WD142"class="WD142">Deep carmine pink</option>\n \t\t\t\t\t<option value="Wild Strawberry" id="WD66"class="WD66">WildStrawberry</option>\n

\t\t\t\t\t<option value="Cream" id="WD72" selected="selected"class="WD72">Cream</option>\n

\t\t\t\t\t<option value="Tangerine yellow" id="WD94"class="WD94">Tangerine yellow</option>\n

 

I want to pick up the color that is selected in a drop down menu in the front end, in the response this color line has selected="selected" in it. This is however random for each instance hence the regex has to pickup the color name from the line which contains selected="selected".

 

I tried using web_reg_save_param_regexp with the regular expression <option value="([^"]*)" id="[^"]*" selected="selected but there are two dynamic values i.e. value and id.

 

I want to use a simple web_reg_save_param where I can use regex in the boundaries so as to pick up the color name from the response. So far what I have is:

 

    web_reg_save_param_ex("ParamName=SelectedColor", 
    "LB/IC=\t\t\t\t\t<option value=\"",
    "RB/ALNUMIC=\" id=\"[^\"]*\" selected=\"selected\"",
    "Ord=all",
    "Search=body",
    LAST);

 

OR


    web_reg_save_param_ex("ParamName=SelectedColor", 
    "LB/ALNUMIC=selected=\"selected\" class=\"[^\"]*\">",
    "RB/IC=</option>\n",
    "Ord=all",
    "Search=body",
    LAST);

 

However this gives me an error Action1.c(73): Error -26396: The "RB/ALNUMIC=" id="[^"]*" selected="selected"" argument (number 3) is unrecognized or misplaced   [MsgId: MERR-26396].

 

Can anyone please help me in using regex in the boundaries for this function? Thanks a lot, and kindly let me know if more details are needed!

Automate interaction with VUGen using UFT

For recording VUGen scripts, we automated the test scenario using QTP 11.5 and VUGen 11.x. We also automated the interactions with VUGen, e.g. choose the protocol, insert transaction, comment etc.

 

Now, we are using VUGen 12.02 and UFT 12.01 . The problem is to identify the particular GUI objects in VUGen 12.x. It is just a window. Menubar, buttons etc. can not be identified by UFT's object spy. Partially, we can use VUGen shortcuts using sendKeys in the UFT script. But it would be nice if HP's object spy (UFT) could identify GUI objects of HP's product VUGen ...

Hi,

 

I have a web based application which communicates to another application through web sockets. The business process flow is pretty simple where the script logs into the website,selects few records(which opens through socket communication) and logs off. I am using Vugen 12.02 and after recording following fuctions are generated automatically

 

web_websocket_connect("ID=0",          

"URI=ws://xyz/websocket/events",          

"Origin=http://xyz",        

  "OnOpenCB=OnOpenCB0",          

"OnMessageCB=OnMessageCB0",         

 "OnErrorCB=OnErrorCB0",          

"OnCloseCB=OnCloseCB0",          LAST);

/*Connection ID 0 received buffer WebSocketReceive0*/   

  /*Connection ID 0 received buffer WebSocketReceive1*/    

 lr_save_string(WebSocketSend0, "WebSocketSend0");

 

 

web_websocket_send("ID=0",          

"Buffer={WebSocketSend0}",        

  "IsBinary=0",          LAST);   

  /*Connection ID 0 received buffer WebSocketReceive2*/

 

 

No while replay the script fails at the web_websocket_connect with HTTP400 Bad request error. There are two exra files generated WebSocketBuffer.h and WebSocketCB.c. I don't know how to handle these generated functions and how to fix the error. Please help

Performance Testing a Windows applications... LR?

Hi,

 

I need some advice. I am trying to Performance Testing a non-web based application. The Protocol Advisor for LR12.02 tells me to use COM/DCOM and/or Windows Sockets. Neither of these protocols produce usable code to create/modify scripts from.

 

I asked someone who is more experienced than I , what to do and I was told that Load Runner cannot be used to do this type of testing. She also said I would have to use a tool like Junit.

 

Can someone please confirm that LoadRunner cannot be used for this? Also, coming from strictly a LR background, what tool can I try to use to create these performance tests.

 

I would really appreciate any type of advice and/or recommendations.

 

Thanks!

Hi All, I am building a script for web service testing in load runner. the Functional Team are using the SOAP UI tool in which they are using a Web service Security policy that has been setup at the SOAP UI Tool. They are invoking a Java Keystore file. They provide some username and password and more settings in the SOAP UI. The Header part in the SOAP UI message is empty whereas when we monitor the traffic going outside the SOAP UI in the HTTP Log the username, Password, the key (using the JAVA Keystore), the URL pointing to the policy and stuffs are getting passed in the tag. 1. How do i implement the same in the Lod runner script? 2. I am able to build the script, but the key is getting generated when the XML gets to the server (using the .jks file). How can i generate the key for each iteration. should i include any JAVA code. Please help me folks...!!!!
