A shopping cart is the centerpiece of almost every e-commerce website.
In fact, this component is the first thing that makes an e-commerce store different from just an online catalog. Working with issues and challenges related to the cart is something you’ll never forget.
The Russian novelist Leo Tolstoy, at the opening of his novel Anna Karenina, writes ‘All Happy families resemble one another, but each unhappy family is unhappy in its own way.’ You know, the diversity of cart-related issues I have been observing in the SAP Commerce projects, made me think that Tolstoy meant the developers as well. The diversity of the issues and challenges in this component is so vast that every case is different.

Performance testing is especially important in cases where concurrency may be the source of the problem. To recognize and fix such issues timely, it is recommended to perform regular performance testing, ideally integrated into the build and deployment pipelines. This article is devoted to Apache JMeter, one of the well-known tools for automated (and) performance testing.
