Working with web services Protocol

Web Services:

Web Services in loadrunner: We can do web services scripting in two ways:

1.       By using Web Services Protocol. (Need additional License)

2.       By using Web Protocol.

Scripting Using Web Services Protocol:

I have taken weather web service as example shown in this link.

Steps:
1.       First open the vugen and select Web Services protocol.
2.       Click on Manage Services on top nav bar and Click on Import and give the WSDL URL which is usually ends with wsdl
http://www.webservicex.net/globalweather.asmx?WSDL.

Now Click on Add Web Service Call on top nav bar. Give the Input Arguments and Leave the out put arguments empty. And click on ok. As shown in the following image.

It will create a script in loadrunner as shown below. You can perform the steps one by one in this way for all the web services steps. You can use lr_xml_find and lr_xml_get_values to validate the page.

web_service_call( "StepName=GetCitiesByCountry_101",
        "SOAPMethod=GlobalWeather|GlobalWeatherSoap|GetCitiesByCountry",
        "ResponseParam=response",
        "Service=GlobalWeather",
        "ExpectedResponse=SoapResult",
        "Snapshot=t1396977083.inf",
        BEGIN_ARGUMENTS,
        "CountryName=India",
        END_ARGUMENTS,
        BEGIN_RESULT,
        END_RESULT,
        LAST);

Using Web Protocol:

We can create the same request using Web (HTTP/HTML) protocol. You need take the xml request as shown in the following and place in the web custom request.

XML Request Example for Web Custom Request
XML Request Example for Web Custom Request
You need to keep this soap request in the web request body. As shown below and you can capture all the response using correlation function. You can also add check point using web_reg_find. The url should end with .asmx as shown in the request.

web_reg_find("Text/IC=New Delhi",
        LAST);

  web_reg_save_param_ex(
        "ParamName=Web Service Response",
        "LB=",
        "RB=",
        SEARCH_FILTERS,
        LAST);

    web_custom_request("Weather SOAP Request",
      "URL=http://www.webservicex.net/globalweather.asmx",
      "Method=POST",
      "TargetFrame=",
      "Resource=0",
      "RecContentType=text/xml",
      "Referer=",
      "Mode=HTML",
      "EncType=text/xml; charset=utf-8",
      "Body= Your Request should be here as shown in the following image"
      LAST);

Lr Advance Param Function In Loadrunner With Example

This function is not recorded during recording. We manually insert this function whenever there is a need of it. lr_advance_param works depends upon the settings we give in parameter list (ctrl+L). lr_advance_param is like update value on each occurrence. Whenever we want to update a parameter value in the same iteration we use lr_advance_param. For example when we want to use two parameters Google and Bing in one Iteration. Usually the Vugen takes the first value google and if we want to use the second value in the same iteration we use  update value on each occurrence  in the parameter settings. We can do the same using lr_advance_param function. Example: I have set following settings in Parameter Select Next Row:  Sequential Update value on:  Each Iteration If we want to take the next value in the pramater list we use lr_advance_param as shown below. Parameter Name:  DomainName Google Bing Yahoo Ask Vugen Script: Action () { web_u

web_set_max_html_param_len

The  web_set_max_html_param_len  function sets the maximum length of any HTML string which VuGen can retrieve and save in a parameter. The default value for the maximum length of a parameter that can be captured during correlation is 256 characters. To retrieve a string longer than 256 characters, use  web_set_max_html_param_len  to increase the maximum valid length. An attempt to save a string whose length exceeds the maximum length will fail

Error -27492: "HttpSendRequest" failed, Windows error code=12057 (certificate revoked) and retry limit (0) exceeded for URL="

This error occurs when using WinInet replay instead of sockets with Integrated Authentication enabled in run-time settings. The purpose of this was to allow vusers to use SSO with SPNEGO authentication in an IBM WebSEAL environment. After spending some time with the mystical HP level 3 support, they identified an undocumented flag which helps out significantly in this. So, instead of using the WinInet replay engine (which is not encouraged by HP) you should do something similar to the following. vuser_init() {             // Preferred run-time settings             // Browser -> Browser Emulation        // [ ] Simulate a new user on each iteration        // Preferences -> Options        // Enable Integration Authentication [Yes]             web_set_sockets_option("INITIAL_BASIC_AUTH","1");             web_set_user("DOMAIN.LOCAL\\username",                         "password",                         "s
