Recordring Test Scripts in JMeter

Record Testing help tester to record & run their activity against test target. It is a type of automated testing but for multiple users. This tutorial guides you on how to use Proxy Server to record your Test.

The Proxy Server allows JMeter to watch and record user activity while they are browsing web application with a normal browser.

The Test Plan consists of all actions that you need to execute your performance test script. The test plan can be taken as a practice area or temporary storage as the test plan.

The most important component in HTTP(S)TestRecorder is which can record the scripts directly, and the tester can put the load on those later on.

Introduction to JMeter

Basic Settings to do While Recording the Test Scripts

  • Launch the JMeter in your system.
  • Once the JMeter has opened, Right-click on the Test Plan-->Add--> Non-Test Element-->HTTP(s)Test Script Recorder
  • The HTTP(s) Test Script recorder page will look like, as shown below.
  • If you want, you can change the name of the Test script recorder, or else you can keep the same name.
  • The port number inside the HTTP(s) Test Script Recorder represents the user actions. That means JMeter is listening to the port number for any further actions to record.
  • And you can consider HTTPs Domains as an optional field because the JMeter automatically captures your domain name.
  • Next, there are two tabs, such as Test Plan Creation and Requests Filtering.
  • Where the Test Plan Creation contains two fields, such as Target Controller and Grouping under Test Plan Content.
  • The Target Controller is used to store the Recorded scripts.
  • Click on the Target Controller and select Test Plan>HTTP(s) Test script Recorder.
  • Next, click on the Requests Filtering tab, which is used to filter the Images, adds, and buttons, and so many components that are generated on the full website.
  • But do not need all the components which are generated on the website; basically, we just need HTTP Request and Response.
  • You can exclude elements on the UI like images and others using Add Suggested Excludes while recording the Test script.
  • If it has come across any unnecessary thinks, then it will just skip them.
  • So These are the basic settings you need to do while recording the Test Script.

Installation and Configuration of JMeter

  • So that we have set a proxy to our browser
  • Now go back to the Jmeter window and then click on the Start button to start recording.
  • Before recording anything that you have to ensure that you need to insert one certificate into your browser
  • If you want to connect through HTTPS and start recording securely, that specific https website needs a certificate to trust you.
  • Without any certificate, you cannot record any https website.
  • And this certificate will be provided by the JMeter.
  • After configuring everything in the connection setting, just click on the start button in the JMeter, you can see the pop-up message.
  • Now the Root CA certificate has been created in your JMeter bin directory.
  • Once you install that certificate in your firefox browser and then your browser interacts with HTTPs, and it recognizes that the certificate provided by the JMeter, then it works as expected.
  • Go to your browser, and when you are still in the Settings page, search for a Certificate. And then click on the View Certificate option.
  • Next, go to the Authorities and then click on the Import.
  • After clicking on Import, go to your JMeter bin folder, there you can find the ApacheJMeterTemporaryRootCA certificate.
  • Once you find the certificate, click on Open, so that it will install the certificate into the browser.
