Testing Web service Requests Performance

What do you know about web services testing? In simple words, this is also refer to internet connectivity testing, to ensure both sites (point A to point B) are linked up and able to transmit electronic messages over an unsecured or secure channel.

There are tools available to conduct web services testing automatically.  Tools like SOAP, a valid WDSL file, HTTP get/post are some of those tools that most engineers use.

In all web applications’ design, page loading performance is the key factor not to be neglected.  Imagine you have hundreds of users accessing a single web server to get their requests send back to their browsers all at the same time.  How will the web server able to sustain the same response time to not just one requests, but to the hundreds and not to mention some of them from this group are requesting the same information.

This is how you can start off a ‘simple testing’ to understand the current web server’s request loading performance by creating a manual test script.

  • Using JMeter,  at the number of threads to send to the web server.  The number of threads represents the number of users accessing the web server.
  • Add the web service request that you need to perform this testing.  The web requests are also refer to the requests that users (threads) access to to understand the request loading’s response times back to the clients.
  • Add a report tool that allows you to capture all the web requests’ calls to and fro between the clients.  And this allow you to analyse the results and determine the work plan to enhance the server’s performance.

If designing a tool seems to be a tedious job to work on or due to time constraint, one way (not the best effective method) is to execute the actual, end-to-end processes from the application, to the web server and finally to the client machine.  The times taken will be based on the time a particular record from one web service call is received at the web server, the time the record is loaded into the database of the client’s application.
