How to locate your IP Address

  • To locate your IP Address, launch the Command prompt and type ipconfig for Windows / ifconfig for Linux, and press ENTER button to get the IP address.
  • We will use this IP address on our mobile device- iOS or Android phone to set up the proxy.
  • Firstly, you will need an appropriate Apache JMeter Temporary Root CA Certificate to save it to your phone.
  • Download the zip file for the certificate for your required operating system and store it in the mail.
  • Install the certificate by mail on your mobile device. It will ask to apply the lock. Then a notification pop-up displaying the network can be monitored.
  • Now, let’s start the actual configuration process for the mobile.

  5. Now, set ‘Proxy Hostname’ as your PC IP address and ‘Proxy Port’ to 8888 as we have set up in the JMeter proxy server.Mobile Port
  6. Save the changes you made, Now, you can start running the application on your mobile device and its requests will be automatically recorded in JMeter.

iOS device configuration:

  1. On iOS device go to Settings > Wi-Fi option (Shared Wi-Fi network should be same for both mobile and PC where JMeter is installed).
  2. Click on the connected network.
  3. Select the ‘Manual’ option as HTTP Proxy.
  4. Set the ‘Server’ as your PC IP address and ‘Port’ to 8888 (or any available port) as the JMeter proxy server.

Start Recording Your Mobile Web Application

By now you must have understood the mobile configuration process. Now, it’s time to open the web application you usually need to test and use.

  1. Launch the application on mobile and every request will be recorded in JMeter.
  2. Before running any application on the device, make sure you click the ‘Start’ button on the HTTP(S) Test Script Recorder in JMeter.
  3. Open the mobile application for which you want to do the load test, and play with the functionality the way you want to record functionality in JMeter.
  4. Since we have set the mobile connection to JMeter’s proxy, thus all the test flows are recorded in JMeter’s test plan.
  5. Once you have recorded all the test flow of your application, stop recording by the ‘Stop’ button on the ‘HTTP(S) Test Script Recorder’ in JMeter and save the test plan.Stop
  6. Now run your test plan by clicking the ‘Play” button displayed in green at the top. This will run the recorded script as per your thread setup.
  7. After playing the test plan you can see the response of each request in the ‘view result tree’ listener.View Tree

Your script is ready to run the load. You can further refine it by adding correlation, parameterization, etc.
