Performance Testing is not only API

When you think of performance tests, you probably mean tests at the API or GUI level. And you are right! Because they are usually enough. What happens when we need something more? Are you familiar with the Shift-Left approach? What if we applied this concept to performance tests? What if you could use your existing tests (including unit tests!) to do it cheaply? Let’s find out! Using tests at the lowest level of the testing pyramid you can choose one of three solutions to achieve the aforementioned concept. Using a well-known library (with license limitations), going with an open-source project (with multiple issues), or coding your own solution. When you make your decision you still have a lot to think about. How to choose the best methods to cover? What to do with the raw results? Should it be used as a prevention or baseline? Within this talk, I would love to share the path I took and the lessons learned. Last but not least. Did we manage to go live or did it end as POC?
