When testing at scale, it is inevitable that at some point your load test will encounter error states. It may even be a condition itself that is tested. Therefore, it is essential that we have a capability to capture and analyze error information. In this brief article, we will detail how to intercept and log errors in your k6 load tests. Intercepting and Logging Errors Ideally, we would like to save errors to a retrievable logRead More →
When writing your k6 test scripts, there are certain common tasks that are recurrently encountered. In this post, we will discuss examples on how to accomplish several of these common tasks. Most of these examples are illustrated in the official k6 documentation pages. Entering Data into Web Forms User submission forms are a common target test endpoint. Tests such as these must be designed in a way that form fields are identified and mapped to usefulRead More →
In previous posts we have covered the ability to use k6 for scalable load testing, however k6 is also a suitable framework for creating functional tests. In this brief post, we will show you how to get started with using k6 as a functional testing tool. Assertions in k6 There are two basic ways to write assertions in k6. One is using the built-in check and group functions. Perhaps a better alternative is to use theRead More →
Even though k6 comes with an impressive assortment of built-in modules, there is an additional ecosystem of more than 50 officially supported plugins available for import. These specialized libraries can easily add functionality to support your specific load testing needs. In this brief post, we will cover some of the most useful k6 extensions. xk6-csv – As perhaps one of the most ubiquitous portable data formats, the CSV file has found an essential role in distributingRead More →
When it comes to load testing, there are two platforms which must be mentioned. k6 and JMeter have established themselves as the de facto standards in the performance testing space. In this article, we will compare and contrast the features of each, to help you better decide which technology is right for you. A Brief History JMeter was introduced more than 20 years ago, and in that time has become one of the most utilized performanceRead More →
