As websites, web applications, APIs, and services become more and more critical, it's import to design and build applications so that they scale well with a large number of requests. To actually test and verify the behavior of services under load, testers and developers can perform load and stress tests. For web applications, a load test would usually involve defining, writing and running test scenarios. A test scenario could be a script that simulates the behavior of a typical user across multiple pages of a website or web application. Once you defined your test scenarios, you can execute it by simulating many concurrent virtual users and monitor how your application behaves. Likewise, for APIs and other services, the idea is to generate requests that are as realistic and similar to a possible load of your production environment, so you can optimize and scale your application and services based on accurate and realistic data. There are various tools that you can use to build, co
