In our last some post with our JMeter Series, we saw introduction of JMeter and its related components. This topic is kind of off topic in JMeter series, but still we need this to understand before moving forward.
We already know what Fiddler is, if you are new to it, please go through details here real quick to get an insight on Fiddler.
As you know in JMeter we will mostly work with HTTP request (Web Applications), we might sometimes need an advanced option to debug our HTTP request and response. Within JMeter we already have Request and Response tabs, but still Fiddler can be more handy (Since its built for that purpose).
In order for us to link JMeter with Fiddler we need to do following steps
First we need to know which port Fiddler is listening to grab the request and response. This you can naviagate in Fiddler to Tools à Fiddler Options à Connections Tab as shown below
As you can see above, currently Fiddler is listening on port number 8888
Now we need to run our JMeter on port number 8888 , which we can do via command line option as shown below
All we are saying here to JMeter is to run on port number (-P) 8888.
Now while running tests in JMeter, we can see actual request and response in the Fiddler window as shown below
In all our upcoming discussions, we will work with JMeter along with Fiddler.
