How to work with REST API web services in Loadrunner

[laxmi narayana]

Hi Guys,

Does anybody have idea on how to work with REST API in Load runner
using web services???

Thanks,
Laxmi narayana

More than often, HTTP/HTML protocol is used for recording RESTful web service calls. Alternatively, if you are know the core concepts of web services technology and if you are provided with WSDL files and/or a recordable interface then web services protocol in LR can be used. 

 

        Be it, RESTful or SOAP, the key factor which actually matters to help you decide which protocol to use is the underlying transport layer protocol used by your AUT. If its HTTP then any of the aforementioned protocol in LR should do the job. If its JMS, then only Web Services protocol will work.

Hi Chaithanya,

Thx for info.Web services can done by using WSDL file.But for dealing RESTful web services we need WADL file(This consists of GET,POST,PUT,DELETE methods).I have tried to import WADL file,but LR is not supporting WADL file.

               Can you please provide me a sample script if you have already worked on it?.

Thanks,

May I ask you again; what is the transport protocol used by your application? Is it HTTP or JMS?

In Rest API, transport is always Http. I dont believe there is any JMS. I have not come across any till now. 

there are four pillars as you may call it in ReST web service calls. 

GET, PUT, POST, DELETE.

Please find this interesting blog, which talks about performance testing ReST APIs using loadrunner.

http://randomsync.blogspot.com/2010/05/loadrunner-scripting-challenge.html

We recently tried scripting, and we were able to do using normal http protocol.

You can use web custom requests as these ReST APIs are URI based. 

We are still on learning phase.

Hi Chaithanya,

I not doing it by recording...I need to do it by importing WADL file.(Same as we do it by using web services protocol by importing WSDL file).

Restful API work only on HTTP. JMS can not come into picture.

Normal Http protocol should work in this.

If you cannot import, then record.

 

If you cannot record, then program. 

 

If you cannot program, then borrow a programmer.

 

If you cannot borrow a programmer, then you are out of luck.

 

Read up on web_custom_request() and overall architecture for RESTful web services.    This should provide a path for you in the integration with LoadRunner.    Nothing stops you from writing your own parser to read a WADL and output appropriate web_custom_request() syntax…should that be the route you decide to take.
