If you need to create complex behavior from the simulated virtual users in the load test, the built-in capabilities of out-of-the-shelf products may not be sufficient. For example, parsing output formats from an API response to create the formatted inputs for an API request may be difficult for a particular load testing tool, but a quick and easy exercise for a high-level programming language.One of the possible ways is using designated libraries to write our own simple load generator from scratch. For our project, this approach has proven to be a faster and reliable way to address the concurrency issues in the SAP Commerce Cloud custom code.  In this article, we explain how to write a load generator from scratch with Python.  Read More »
