Disclaimer: This post is for those still using Beanshell. However, you should know that the Philippe Mouawad, JMeter contributor, has asked us to pass on that everyone should “avoid Beanshell in favor of JSR223 + Groovy because Beanshell is old, slow and does not support Java 5 and upper syntax.” If you still will be using Beanshell for whatever reason, here are Beanshell for JMeter Best Practices. JMeter has powerful abilities to perform general tasks outRead More →

Load Testing Troubleshooting

Anyone who has done load testing knows it’s a lot more than creating a script and running it. There are going to be times when it requires what we call ‘Advanced Load Testing Troubleshooting’. Here is a real case of a RedLine13 customer who was trying to figure out what was causing an unusual load testing graph result. The issue was the graph Percentiles per Page Response Time graph. But sometimes the problem we see isRead More →

People often get confused in the usage of JMeter Loop Count and JMeter Thread Count and more importantly, how will it impact their load test. Do you know the answers? Here are two scenarios: Scenario 1: If the number of thread count is 10, ramp-up time is 10 and loop count is 1. Scenario 2: If the number of thread count is 1, ramp-up time is 1 and loop count is 10. What is the differenceRead More →

RedLine13 Users

RedLine13 Users from across the globe have a lot to say about what’s important to them when load testing. Singapore Lyon Lim, Cofounder and CEO of PigeonLab, maker of PigeonHole Live: “An indispensable tool we use to load/stress test upcoming features, as well as optimising performance. Beneath the hood, your tech is solid! RedLine13 has been able to help us test large scale events for Pigeonhole Live. For example, before we released Quiz, we made sureRead More →

API metrics endpoint

The new API metrics endpoint gives you full access to performance data within your RedLine13 test. Instead of downloading the stats data you can query for a single metric or multiple metrics with your test. You can use this data to build your own graphs or trending information. We built this because of a customer request so that they could create their own dashboard. See the API documentation. And for parameters and format, see the new endpoint.Read More →

Load Testing in a Continuous Integration Environment

In this blog post, we will talk about Load Testing in a Continuous Integration Environment and how to effectively integrate with cloud systems using RedLine13. The crucial point of the this blog post is that we are preparing our load test script just using Selenium code. Before we begin our example, let’s briefly talk about the technologies used in Continuous Integration (CI) processes in our post. Jenkins is an open source automation server and an integrationRead More →

Data Driven Testing with Excel Files

In our previous blog post, we wrote about Data Driven Testing (DDT) using CSV files in JMeter. Excel files are another popular approach. This blog post will show step by step how to do Data Driven Testing with Excel files. Contrary to CSV files, we will import some external libraries in JMeter and then write a few lines of code to perform data driven tests. The other important aim of this blog post is that insteadRead More →
