Our load agents run inside your AWS environment. So if you have a tunnel or traffic management place already you might not have to do anything.  If your applications are running on AWS but perhaps in a different vpc, region, or accountRead More →

Application load testing for API endpoints can be done quite easily. You could even do this to compare different API platforms that you’re considering using. That’s what we’ll do here with a real case. Zip Code API’s have become very popular because of the data they can provide easily and inexpensively. For example, one API when passed a zip code returns the city, state, latitude, longitude, time zone and more. Another will return all zip codesRead More →

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 →
