Create a Performance Test with BlazeMeter And JMeter

Welcome to the ultimate guide on harnessing the combined power of BlazeMeter and JMeter for performance testing. In this section, we'll explore how integrating these two industry-leading tools can revolutionize your testing practices, enabling you to create robust and scalable performance tests with ease.

Prerequisites

The following prerequisites will be required to complete this tutorial:

• BlazeMeter browser extension. If you don't already have it, add the BlazeMeter extension to your browser.
• A BlazeMeter account. If you don't have a BlazeMeter account, create one for free before you begin.
• JMeter. If you don't have JMeter installed, download JMeter.

Getting Started with BlazeMeter

Let's kickstart your journey into performance testing excellence by diving into BlazeMeter. In this section, I will guide you through the process of getting started with BlazeMeter, and configuring your first performance test. Get ready to unleash the full potential of BlazeMeter and take your testing efforts to new heights.

1. Select the Icon in your browser.

2. In the Test name box, enter a name for the test. Select the Record button, to start recording.

   

3. Select the Add Step button, to add steps for each action. When finished, select the Stop button.

   

[!NOTE] When the script is saving the BlazeMeter icon will blink.

4. Select Edit, and then JMeter Script... (If not logged in to BlazeMeter, you will need to be for the next steps).

   

5. Select JMeter & Selenium combined (YAML), and then select Save.

   

6. Select the .JMX button to export the JMeter script.

   

Integrating BlazeMeter with JMeter

Now that you're familiar with BlazeMeter, it's time to explore the seamless integration with JMeter. In this section, I will show you how to integrate BlazeMeter with JMeter to leverage the scalability and analytics capabilities of BlazeMeter while harnessing the flexibility and customization options of JMeter. Get ready to streamline your testing workflows and maximize the efficiency of your performance testing efforts.

1. In Microsoft Windows, Open the bin folder of JMeter and run the JMeter.bat batch file.

   

2. In the upper-left of the screen, select File > Open.

   

3. On the Open screen, select the Script, and then select Open.

   

Edit Thread Group properties

1. In the Test Plan, select the Thread Group. This is where you enter the essential information required for the performance test. Enter the following values:

   

   Field	Value	Description
   Name	5 Users	Name of the Thread Group
   Comments		Comment related to the Thread Group
   Action to be taken after a Sampler error	Continue	Continue with the test when an error occurs
   Number of Threads (users)	5	Mimics the number of user(s) or connection(s) to an application
   Ramp-up period (seconds)	10	Time to create all of the threads (or how frequent requests should be sent by users)
   Loop Count	1	Number of times the test will repeat for the thread group (or quantity of requests that should be sent)
   Same user on each iteration	Checked	If checked and the Test Plan utilises HTTP Cookie Manager - Cookies returned in the first response for subsequent requests will be used
   Delay Thread Creation until needed	Unchecked	If checked it stops JMeter allocating memory for all threads (users) when the performance test starts
   Specify Thread lifetime	Unchecked	Specify a duration and startup delay
   Duration (seconds)	0	Specify a duration for the whole test
   Startup delay (seconds)	0	Delay time before a thread is started

Add listeners

1. In the Test Plan, right-click the Thread Group, select Add > Listener > Summary Report.

   

2. In the Test Plan follow step 4 above to add the following listeners to the Thread group and each Transaction controller.

   Test Plan Area	Listener
   Thread Group	Summary Report
   Thread Group	View Results Tree
   Thread Group	Response Time Graph
   Transaction Controller	Summary Report
   Transaction Controller	View Results in Table
   Transaction Controller	Aggregate Report
   Transaction Controller	Graph Results

   

Executing and Analysing Performance Tests

With your performance tests created and your tools integrated, it's time to execute and analyze your tests. In this section, I will guide you through the process of running performance tests in BlazeMeter, monitoring test execution, and analyzing test results to identify performance bottlenecks and areas for improvement. Get ready to gain valuable insights into your application's performance and optimize its scalability and reliability.

1. In the JMeter screen, select the button.

   Once running, a green indicator icon will appear in the top right of the Control Panel. JMeter will ramp up the total number of active threads to 5 in approximately 10 seconds with a delay of 2 secs between subsequent threads. The indicator box will turn to grey when the test is complete.

2. When the performance test has completed. Select the Summary Report listener in the Thread group to analyse the results.

   

Conclusion

In conclusion, the integration of BlazeMeter and JMeter offers a powerful solution for creating, executing, and analyzing performance tests with precision and efficiency. By following the steps outlined in this guide, you can streamline your testing processes, identify and address performance issues early in the development lifecycle, and ensure the optimal performance of your applications.
