The Rotating JTL Listener is a component that can be added to JMeter tests, which has the effect of segmenting JTL output into sequential files. This feature can be especially useful for very large tests, where it would be desirable to break one large JTL file into several smaller files to make them more manageable. Another use case might involve a background process that consumes result files in similarly large tests. In order to add the RotatingRead More →
Test plan design, while not always application programming per se, definitely shares some concepts of the latter. A common principle of software development is to minimize repeating code. In this article we will show you how Test Plan Fragments can be leveraged in JMeter test plans to reduce repeated elements. Basics of Test Plan Fragments In essence, Test Plan Fragments are groups of test logic which can be referenced by various JMeter controllers, that do notRead More →
If you are new to JMeter, you have come to the right place. In this post, we will walk you step-by-step through creating your first, functional JMeter test plan from scratch. We will guide you through how to install JMeter on your local device and navigate the user interface of the test plan editor. Starting from a blank canvas, we will create a basic test plan. From there, we will use RedLine13 to run your testRead More →
Within the paradigm of application testing, there are two broad categories of tests which are often used to complement each other. While there are dedicated tools for each, there is considerable overlap and many of these tools can be used for either purpose. In particular, tools such as JMeter, while traditionally being more associated with performance tests, can be proposed to execute functional tests. In this article, we will describe what each test seeks to proveRead More →
RedLine13 makes it easy to scale your load tests in the cloud, but sometimes there are a few moving parts to coordinate. While it can be disappointing when a test fails to start, in most cases there are only a few common reasons preventing such a “grounded” test from launching. In this article, we will walk through some of these common scenarios. In each of these cases we will discuss troubleshooting steps and potential solutions. NetworkRead More →
The JMeter Dashboard Report is an HTML-based summary that can be generated from the results data of a JMeter test. When you run your load test with output files enabled on RedLine13, we automatically generate this report. However, this report can also be generated manually on your local machine using the JMeter GUI. Generating the Report Locally To generate the JMeter Dashboard Report on your local machine, begin by starting the JMeter GUI. Navigate to theRead More →
By design, resources in AWS are provisioned through the lens of security. When creating a new Virtual Private Network (VPC), access into this network from the outside world is restricted. In this article, we will go through the steps connecting a VPC to the internet. We will also review common connectivity issues faced reaching resources inside a VPC. Attaching an Internet Gateway The first step to enable VPC internet access is to attach an Internet Gateway.Read More →
JMeter can be run in two modes, with the more familiar GUI mode for designing tests. However, when running your load tests for production data gathering, it is recommended that it is run in non-GUI mode from a command line. This is in fact how load tests are run with RedLine13. But it is also possible to run JMeter in non-GUI mode on your local machine. There are instances where this is desirable, including debugging specializedRead More →
For certain k6 tests, we may want to vary the action taken based on content presented on the target test page. In order to accomplish this, we can use HTML elements to drive conditional logic within a k6 test plan. In this brief post, we will show you how to use k6 to dynamically evaluate HTML elements on a target test page. Importing Required Modules To read content from the page, we will need to importRead More →
In this series, we interview RedLine13 users. Janesh talks about what he likes best about load testing, biggest challenges and advice for someone new to load testing. Why did you get into load testing? I initially got into load testing because I recognized its critical role in ensuring the reliability and performance of software applications, a key aspect of software quality assurance. How did you learn about load testing? I learned about load testing during myRead More →
