TUSB211A-Q1: USB2.0 device side compliance test?

Part Number: TUSB211A-Q1

Hi team, 

We image USB2.0 data is bidirectional as below.

For USB2.0 compliance test, electrical test, we understand Host data "send" and Device data "send" has to be tested. Circuit and data direction image is below.

Is there no test spec shown in USB2.0 comliance test for Host data "receive" and Drvice data "receive"? If no test, do you know its background? Data direction image is shown below.

If no specific test for "receiver" side, how Host data "receive" and Device data "receive" is evaluated as application system level in general? 

In USB2.0 compliance, how do we guarantee received data correct by only Host data "send" and Device data "send" test? 

Regards,
Ochi
