Load Testing

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 →

This is one of our most popular blog posts – File Uploads. Check out a new section #3: Adding Parameters to your HTTP Request. Read below for lots of great information. There are many cases of testing performance of API Endpoints for file uploads. We chose to demonstrate scaling out such a test building our load test plan in JMeter. JMeter supports file uploads natively within the HTTP Request, and Redline13 supports attaching files to your test plan.Read More →

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 →

RedLine13 continues to be the leader in load testing tools supporting the latest from Apache JMeter. This blog post will focus on load testing with JMeter Nightly. JMeter Nightly builds are “interim builds that are untested and unsupported.” Apache makes clear to  “Use at your own risk!” They are intended for use by developers and others wishing to help with resolving JMeter bugs. RedLine13 does a daily pull of the last Successful build of JMeter. When you runRead 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. Pro is a fully customizable Continuous Integration Platform with native Docker support. 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 →
