k6 Browser Tests vs. Selenium

The landscape of browser testing has traditionally been dominated by tools such as Selenium which incorporate a real web browser (e.g., Chromium) and orchestrate prepared tasks against a target test site. This differs from other popular load testing frameworks such as JMeter where the basic HTTP requests are sent and the responses directly analyzed. Browser testing confers the advantage of interacting with a website in the same way that a user would. This is achieved byRead More →

Troubleshooting Common Issues with Selenium Tests on RedLine13

Many RedLine13 customers have a need for full-browser testing. This is something we support with Selenium WebDriver. In this brief post we will cover common issues encountered with Selenium WebDriver tests and when scaling load testing on RedLine13. Test Never Completes Occasionally we encounter a Selenium WebDriver test that otherwise appears to run as expected, however never completes. One possible explanation is a simple one, where the driver.quit() statement is omitted. const main = () =>Read More →

Pitfalls of Selenium Load Testing

Tests created with Selenium WebDriver replicate the user experience from the perspective of the UI.  It can be thought of as a top-down approach whereby it accurately replicates the behavior of an end user. Running through a browser instance such as Chrome or Firefox, the test process itself interacts with the actual user interface elements of a target test application. This is in contrast to many other testing frameworks.  One of the most popular is JMeter,Read More →

Selenium Basics for Load Testing

We have several examples available to help you get started with Selenium WebDriver testing on RedLine13. In this brief post, we’ll go about constructing a Selenium script from scratch. We will also review the basic necessities and also common pitfalls when deploying on RedLine13. Selenium supports several languages for scripting, with JavaScript being a popular choice. The first line in our script should be instantiating the redline WebDriver instance: const redline = require(‘redline13-webdriver’); We will wantRead More →

We are pleased to announce that you can now use Selenium WebDriver to create and run performance tests on RedLine13. You only need change how you load the driver; this will not impact your existing WebDriver scripts at all. By using your existing scripts (or new ones), you can launch PhantomJS, Chrome, or Firefox instances in the cloud simulating hundreds or thousands of users. We have load tested a 5,000 real user simulation with a WebDriverRead More →
