|
* Sockets stresstest
|
|
*
|
|
* This file uses the lwIP socket API to do stress tests that should test the
|
|
* stability when used in many different situations, with many concurrent
|
|
* sockets making concurrent transfers in different manners.
|
|
*
|
|
* - test rely on loopback sockets for now, so netif drivers are not tested
|
|
* - all enabled functions shall be used
|
|
* - parallelism of the tests depend on enough resources being available
|
|
* (configure your lwipopts.h settings high enough)
|
|
* - test should also be able to run in a real target
|
|
*
|
|
* TODO:
|
|
* - full duplex
|
|
* - add asserts about internal socket/netconn/pcb state?
