This is our most popular blog post and we’ve added more extractors. This post explains how to use the regular expression extractor to extract the key from the response of your first request and use the extracted key for subsequent requests. We call this JMeter Extract and re-use. Now you can use additional extractors, the JSON extractor and Xpath extractor. We’ve added that to the end of this blog post. You can use the regular expressionRead More →

Free Trial is not Free - RedLine13 is Free Load Testing

When doing a Free Load Testing Comparison, ‘Free’ seems to mean very different things! Let’s be honest. Free load testing is not the same as a 30 day free trial. What good is that? You’re going to be paying on day 31, day 32 and on and on. And those ‘free trials’ have limitations on ‘free load testing’. The whole reason that RedLine13 got into the load testing business was because we had seen how expensiveRead More →

RedLine13 is answering Stack Overflow questions in Spanish and Portugues

You may have seen answers on Stack Overflow regarding JMeter Load Testing and RedLine13. Recently there have been some questions in Spanish and Portuguese with Stack Overflow answers in Spanish and Portuguese.

Amazon Web Services (AWS) just introduced the next generation Amazon Elastic Compute Cloud (EC2) burstable general-purpose instances, T3. Amazon says that “T3 instances offer a balance of compute, memory, and network resources and are designed to provide a baseline level of CPU performance with the ability to burst above the baseline when needed.” See the AWS announcement for details. RedLine13 supports T3 instances for all RedLine13 pricing levels. In addition, RedLine13 is announcing support for R5Read More →

Recording signifying File Upload with JMeter

This article demonstrates how to do a file upload with JMeter. This will show the steps when you have a load testing scenario where file upload is required. Recording File Upload with JMeter The simplest way of creating a JMeter test plan is recording the corresponding request using the HTTP(s) Test Script Recorder. JMeter acts as a proxy server, capturing all traffic between a web browser and the application under test (AUT), and converting it intoRead More →

HTTP Authorization Manager keeps your script from being rejected

Sometimes you will need to load test URLs that are restricted from public access. The types and resources can vary from corporate libraries and knowledge bases to targeted forums or others. All tend to have limited or restricted access. When you try to access such URLs, a browser generates a pop-up window and asks for username and password to authenticate. You should handle this in your JMeter script to get access to the web resources. ThisRead 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 →

Overview – Data Driven Testing Data Driven Testing (DDT) is a popular testing approach, especially for functional testing. The same business requirement or use case can get different reactions when using different data. One of the most popular uses is entering forms. The basic aim of this approach is to design one test case and implement it with different data sets. To use data-driven testing in this scenario, you can record a single automated test, andRead More →

Database

Database load testing is used to test database applications for performance, reliability, and scalability. We will use varying user loads to identify performance issues. Load testing simulates real-life user load for the target database applications and is used to determine the behavior of the database applications when multiple users hit the applications simultaneously. This article will guide you how to configure and run JMeter Database Testing. We will create a simple test plan to test aRead More →

Pro Tip - Expert Terrain

In this example we will show how to extract AWS instances parameters using JSR223 Sampler on JMeter. In addition, you will learn how to run bash command scripts on remote linux servers using JMeter. This is a JMeter Pro Tip that can save you time.   In some cases it is necessary for the load test to send a linux command to  the remote linux server. For example, after completing a load test and before retesting again youRead More →
