We can develop very dinamic scenarios with all the logic and customized metrics that one can think of. The k6 open source platform is quite straightforward and its configuration are fairly easy to implement in our scripts. Running scalable tests locally or using the cloud support is a breeze. k6 Cloud provides us with great knowledge and real-time graph to analyze every detail our projects' performance trends.
k6 is a great framework that's really enabled us to move quickly with load/performance testing. k6 Cloud has been a major upgrade in comparison to previous testing service — total test runs, quick and helpful responses to our support inquiries, good visualization of test results, active k6 community.
We love the flexibility of k6. It can be adapted to provide whatever information we need, no matter how unique to our platform the situation is. We now have a performance testing framework which tells us exactly what our teams need to know and keeps a watchful eye on our code base for any performance issues that might slip in.
Overall, k6 strikes a good balance between scripting flexibility and execution performance. k6 also offers a comprehensive ecosystem beyond the test runner.
Very good load testing platform. We as a retailer got tremendous help with the load testing to survive Black Friday 2019. Biggest plus is that the tests can be run from command line, and are configured with code.
LoadImpact takes away the pain of setting up complex and distributed infrastructure to load test our application. It's a simple setup and doesn't need much maintenance (write once and reuse every year with a few config changes). The best part of Load Impact is the scheduler which helps us test during times with low user impact (internal and external). I'll definitely recommend their service to anyone who wants to run load tests quickly.
I have used other testing tools like Apache Benchmark, Jmeter, Gatling, and Postman, but k6 outshines them all with its ease of writing workflows using various operations provided by a service. Adding field validations, asserting outputs, generating dynamic dataset, and debugging the tests were all likewise very easy compared to other tools I have used in the past.
The engineering effort of writing tests for just one of our microservices was going to be 2+ Engineering weeks in JMeter, versus the ½ day it took us in k6!
I'm very impressed by k6. I've tested a few load testing tools before, but k6 is by far the fanciest. 🎉
I would gladly recommend this to anyone needing to load test their endpoints. We were using Gatling at work to do load testing and it was very slow to develop in it as we were lacking experience in scala. We found this and never looked back. The impact it had on benchmarking, profiling and tuning the servers was massive. I’m pretty sure the company saves a few thousand dollars every month till today because of those optimizations.
