Load Testing

Alex Podelko wrote about the state of load testing in 2014. He recently did a load testing comparison to see what changed since then. And he realizes that the winds of change have changed it a lot. It’s titled “Are Times still Good for Load Testing?” and is an excellent read. Alex currently serves as a board director for the Computer Measurement Group (CMG), a worldwide organization of performance and capacity management professionals. Read his full bio. It’s crazy (butRead More →

Customers often ask: Which is the best AWS instance for load testing? It’s a great question. However it never has a direct answer:) As an AWS Advanced Technology Partner, we’ve had a lot of experience with AWS. Here’s how we respond. 1 – First, it depends on what kind of testing framework you’re using, whether it’s JMeter, Gatling, Selenium or something else. For simple HTTP endpoint test or simple PHP/Python, start with T class. For otherRead More →

You can already see real-time metrics of your tests. An API retrieves Live Load Test Metrics? Why would you want an API that does that while a load test is running? A RedLine13 customer asked for it and it became clear what the benefits would be. This means that while a load test is running, you can be monitoring the test with an API and initiating actions as soon as some event occurs. Which means youRead More →

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 →

What is Load Testing? There are a lot of good definitions. Wikipedia: “Load testing generally refers to the practice of modeling the expected usage of a software program by simulating multiple users accessing the program concurrently. “A better way to define it may be to ask ‘what are the objectives of your load testing?’ We wrote a blog post three years ago about the objectives of load testing: #1 Common Sense of Load Testing. How haveRead More →

Codeship provides Basic and Pro. For Codeship Basic integration, read Load Testing on Codeship with Redline13 – it just makes sense. With Basic you can run any command.

To integrate with Codeship Pro we have used Encrypted environment variables Service definition in codeship-services.yml Build steps defined in codeship-steps.yml 1 – Make your RedLine13 API Key available as an encrypted environment variable Get your RedLine13Read More →

Making sure software behaves properly under a tester’s hands is important, but it’s not enough by itself. More strenuous tests are needed to see if it works day after day in a production environment. Software that will run on heavily used websites is especially in need of that kind of testing. Not all bugs will show up in unit tests and with single users. Automated tests, simulating aspects of real-life concerns, are an essential part ofRead 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 →
