> **Note**
> Assertion Results MUST NOT BE USED during load test as it consumes a lot of resources (memory and CPU). Use it only for either functional testing or
> during Test Plan debugging and Validation.

The Assertion Results visualizer shows the Label of each sample taken.
It also reports failures of any [Assertions](/user-manual/test-plan/#assertions) that
are part of the test plan.
