How to write three times fewer lines of code when doing load testing
This testing application in Lua stores information about car models. I use this application to test database writes and reads. The application has two main components, API and Storage. The API component gives the user HTTP controls for reading and writing, while Storage is responsible for the application's interaction with the database. Here is the interaction scenario: the user sends a request, and the controls call the database functions necessary to process that request. Check out the application on GitHub.
