/* This test checks that a TRRServiceChannel can connect to the server with
a proxy.
Steps:
- Setup the proxy (PAC, proxy filter, and system proxy settings)
- Test when "network.trr.async_connInfo" is false. In this case, every
TRRServicChannel waits for the proxy info to be resolved.
- Test when "network.trr.async_connInfo" is true. In this case, every
TRRServicChannel uses an already created connection info to connect.
- The test test_trr_uri_change() is about checking if trr connection info
is updated correctly when trr uri changed.
