Companies use their data to accelerate business growth and overtake their competitors. To achieve this, they invest a lot in their ETL (extract-transform-load) operations, which take raw data and transform it into actionable information. It’s no wonder, then, that ETL testing is a crucial part of a well-functioning ETL process, since the ETL process generates mission-critical data.

A common complaint that I hear is: “My tests run a lot faster locally than on Sauce Labs.” Sauce Labs is in the cloud and not in your local network, so it makes sense that any given test is going to have some amount of slowdown. The advantage of Sauce Labs is that you can make up this difference by scaling up the number of tests you run at the same time.

“JMeter is old technology”, I hear this a lot. “Let’s use this tool or that tool instead of JMeter as it’s the latest”, I hear this a lot. “We need a lightweight tool without the GUI interface to write our tests as that will make us more agile”, I hear this a lot.

The outline of this article is as follows: Most systems are designed to treat users differently based on their identity. Therefore, users are authenticated via various mechanisms and it's often equally important to test the performance of anonymous and authenticated endpoints. One of the most widespread authentication standards used by today's applications is OAuth. In OAuth, we use a trusted third party to verify the identity of the user.

This year the Selenium Conference was held virtually, and despite that, the conference again offered an exciting place for the Selenium community to meet in order to share and learn about the most popular browser automation tool in the world. The conference offered talks about improved testing practices, new tools to simplify the setup of automated tests, the future of Selenium, and lots of learnings from speakers who shared their use cases and practical advice for how they use Selenium at work.

In this tutorial, we will look into how to integrate performance testing with k6 into your Jenkins Pipeline setup. By integrating performance tests into your CI pipelines, you can catch performance issues earlier and ship more stable and performant applications to production.
