Currently, the most popular approach for API testing is to send a JSON payload file instead of using data with parameters. This post will show how to do JMeter Load Testing with a JSON payload. To perform sending the JSON payload we need a different configuration. First, we need to add HTTP Header Manager into our HTTP Request in order to set Content-Type as application/json.

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 →

But depending on your test, you may need to keep an eye on it. So this post will talk about AWS dataRead More →
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 →

Many secure web applications use cookie data for their session management. On the other hand, there are still a considerable number of web applications that use a URL rewriting technique for the management of their session information. Although it has some potential security risks, there are several advantages to using this technique. For an example, even if a client browser’s cookie is disabled, it still works. The other advantage is thanks to URL Rewriting, users seeRead More →

And he found that load testers use JMeter the most. Alexander continued: “Another interesting trend is that JMeter scripts become a de facto standard.” So weRead More →
