Tests

Are the data volumes transmitted consistent with the capacity of the user's device?

Precisions

The capacity of the user devices to retrieve information is limited. In addition, the user's ability to process data is also constrained. It would be inefficient if the volume of data transmitted were to exceed these limits, as this would lead to a wasteful use of processing resources.

Use Case

Source code checks track API calls parameters to avoid unlimited returns. Development tools & browser console are used to track network flows, size & frequency (CHROME: console / network)
