Programming with Apache JMeter for Testing

Nowadays, more and more HTTP APIs are protected by some authentication mechanisms such as API Key, time-stamping request, request signature and so on. These mechanisms make API testing more challenging. Thus we can not send a test request directly with Apache JMeter. Instead, some extra procedures should be done first.

In this course, you will learn how to modify such JMeter HTTP sample requests both manually and programmatically. We will focus on JMeter components such as Variables, PreProcessors, HTTPSampler, HeaderManager and so on. We will set up the testing environment first, then send sample requests with authentication manually. And we will learn how to use JMeter Variables and PreProcessors to modify our sample requests. Finally, we will focus on script programming in Apache JMeter, especially JSR223 PreProcessor. In script programming, we will learn how to manipulate the current sampler, variables, sample URL, post body, http headers and so on. Eventually, we will write a single script for all testing endpoints, which contains all the knowledge we will learn.

By the end of the course, you will learn script programming with JMeter components and be able to encapsulate your code for JMeter. Finally, your testing skills will be enhanced and you will become a JMeter expert.
