TEST DETECTIVE

I’ve noticed that the subject of performance testing is still a bit of unknown area for most Test Engineers. We tend to focus mainly on functional aspects of our testing, leaving performance, scaling and tuning to developers hands. Isn’t stability a substantial part of software quality? Especially in times of distributed computing, when we’re scaling applications independently and rely on integrations through HTTP protocol. Another aspect is an ability to scale our systems up. In order to be able to handle traffic growth, we have to be aware of the bandwidth limitations. There’re few well known tools among engineers, such as JMeter, Gatling, Tsung, etc. Although these tools are relatively simple to use, what’s often confusing is analysing and taking conclusions from test results. During interviews for Test Engineer role I often meet candidates claiming to be experienced in field of performance testing, but they’re lacking the knowledge of any performance-related metric or elementa...

Performance testing is crucial field of modern software development. Taking into account that in today’s world majority of app’s communication is web-based, it turns out to be even more important. However, it still enjoys less interest than automated functional testing, and publications on load testing subject usually focus on mature and complex tools like JMeter or Gatling. In this post I’d like to introduce command line usage of a super simple and lightweight tool for performance testing of HTTP services, which is Vegeta. Who is Vegeta  Besides Dragon Ball’s character, Vegeta is a simple load testing tool written in GO, that can be used both from command line and as an external library in your project. In order to use Vegeta, download executables from here . It is recommended to set environment variable for ease of use.  For Mac users, you can download vegeta directly from Homebrew repositories: $ brew update && brew install vegeta Vegeta’s Arsenal...
