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 →
JMeter contains a built-in component that can assist in controlling the logical flow of a load test based on internal conditions. Using the If Controller, conditional logic can be set up to either run once for a group of elements, or optionally for each element within a set. Only if the specified condition is “true” will items within the If Controller be executed. Once added to a test plan, the If Controller acts as a containerRead 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 →
Form submissions represent a common use case for performance tests. If your JMeter test needs to automatically fill out form fields from a data source, this is classically done with extractors and variable substitution. Depending on the number of fields in your form and the structure of your web page, this can become complicated. To simplify this process, we will show you how to use the HTTP Form Manager plugin. This component allows you to intuitivelyRead More →
It is not uncommon for network access rules to restrict traffic from undifferentiated traffic from major cloud providers. Such a practice for public-facing applications is a reasonable security measure. However, this can pose some challenges when performing load testing, especially with scale as these resources typically originate from within a large data center. In this brief article, we will show you how to set up X-Forwarded-For headers in JMeter to help navigate this issue and allow yourRead More →
When creating a load test, it is sometimes desirable to control how the rate of requests are scaled over time. k6 provides this behavior through the ramping-vus executor, which allows gradual scaling of virtual users over a specified duration. This enables realistic simulations of user traffic patterns as expected in real-world use cases. In this brief post, we will outline the basics of using this feature in k6. Example Script of Ramping VUs The following k6Read More →
Owing to an efficient design and low overhead, k6 tests have an inherent ability to scale well. Compared to other testing frameworks, users of k6 can often expect less resource utilization. As described in the official documentation, k6 tests scale well on single instances, lending to reduced requirements when performing distributed load testing. In this brief article, we will show you how cloud-based platforms like RedLine13 allow you scale your k6 tests across multiple load generatorRead More →
When creating your test plans in k6, it is a common practice to write the script with a bottom-up approach. In other words, each request is explicitly coded in sequence with a series of http request methods wrapped in flow control. While this method provides the ultimate means of control, tests can also be built using the k6 Browser Recorder. With this alternative, a browser plugin allows you to record a series of interactions with aRead More →
