# [[Test scenarios vs. test types]] Test scenarios and test _types_ are not the same thing, although they are related. However, the difference is mainly semantic. ![[Test Scenarios#^0d51bb]] ![[Load Test Types#^594e45]] - [[Load Profile]] - [[Load distribution]] - [[Load test duration]] - [[Load test ramp-up]] - [[Concurrency]] - [[Throughput]] Identifying [[Load Test Types]] to be used is part of writing [[Test Scenarios]]. A load test type focuses on the _how_ of a load test, whereas a test scenario also includes the _what_ and the _why_. Load test types usually describe the form of a load test rather than its purpose, although in some cases, one affects the other. For example, I would classify a [[User Concurrency Test]] as a test scenario rather than a load test type. In practice, test scenarios and test types are often used interchangeably. In [[API Load Testing - A Beginner's Guide#^f36dd0]], I myself cited load test types as test scenarios.
