How to Add a Variable Number of Parameters in Apache JMeter

By |2022-02-17T09:52:16+03:00July 22nd, 2020|Tags: , , , , , |

Some requests have more than one parameter, and the number of parameters may change. You can also add dynamic parameters according to your scenario. To resolve this issue, we need to use JSR223 PreProcessor provided by Apache JMeter. First, we add an HTTP request as shown below, then we delete all the parameters and add JSR223 PreProcessor. In this example, we choose the groovy language. Then we add a for loop to determine how many parameters we will add, and add the parameter insert code to use it inside the for a loop. When we run the test, we [...]

Using Commandline Parameters in JMeter

By |2021-01-22T13:41:45+03:00May 22nd, 2018|Tags: , , , |

It is a common practice to create performance test scripts by using JMeter GUI. For test execution, however, it would be best to use command line mode of JMeter. So whenever you need to change a parameter like thread number, base url, etc.. you need to go to GUI mode, do some modifications and run your test. We can't call that a good practice. JMeter lets you pass parameters in command line mode. How to Pass Argument via Command Line Basic command line parameter is jmeter -n -t your_script.jmx -n - tells JMeter to run in non-GUI mode -t - specifies [...]

System Stability Test | Part 1

By |2022-04-05T10:23:11+03:00April 5th, 2022|Tags: , , , , , |

Stability Test Stability test is a type of software testing to check the quality and behavior of the software under different environmental parameters. It is defined as the ability of the product to continue to function over time without failure. It is a non-functional testing technique that focuses to stress the software component to the maximum. Stability testing is done to check the efficiency of a developed product beyond normal operational capacity which is known as the breakpoint. It has higher significance in error handling, software reliability, robustness, and scalability of a product under heavy load rather than [...]

JMeter How to Solve NoHttpResponseException

By |2022-01-12T10:56:11+03:00January 12th, 2022|Tags: , , , , |

During load testing, it is very normal that you get some errors for your requests. But sometimes these errors don't occur because of server problems. One of the most common exceptions in JMeter is NoHttpResponseException. To solve this issue, you can try the following alternative solutions. Change the Implementation of Your HTTP Requests On JMeter, choose a specific HTTP request sampler. On Advanced tab, you will see a section called “Implementation”. Change this option to “HttpClient4”. Then rerun your load test. Change Your “user.properties” File Adding some values to your user.properties file [...]

What Does Stress Testing Your Website Reveal?

By |2022-01-04T14:58:01+03:00January 4th, 2022|Tags: , , |

Any software business that expects a significant volume of visitors due to a planned or unforeseen situation should be tested. Non-functional testing is used to assess the software's speed, stability, and scalability and evaluate how the website/application performs when under high load. A stress test is executed to establish the website's breaking point by simulating many visitors, which is the "load," and progressively raising it. When a website reaches a breaking point, it either crashes or suffers a considerable performance loss. In contrast to load testing, which tests the website for a particular load, stress testing raises the load to determine how the website behaves under [...]

Real Time Monitoring with JMeter InfluxDB Integration

By |2021-12-16T09:57:02+03:00December 16th, 2021|Tags: , , |

There are lots of reasons why JMeter is one of the most popular performance testing tools in the market. And one of the biggest reasons is its reporting ability. Even though JMeter provides proper test results for your performance testing sessions, there are some problems as well. When you run your test in NON-GUI mode, you will need to wait until the test is complete to see the results. During long running sessions, seeing results immediately could be really crucial. Also, by applying some integrations -that will be shown below- you will have some sort of APM tool on [...]
