// TODO(dgq): Other scenarios in need of testing:
|
||||
// - Send a serverlist with faulty ip:port addresses (port > 2^16, etc).
|
||||
// - Test reception of invalid serverlist
|
||||
// - Test pinging
|
||||
// - Test against a non-LB server.
|
||||
// - Random LB server closing the stream unexpectedly.
|
||||
// - Test using DNS-resolvable names (localhost?)
|
||||
// - Test handling of creation of faulty RR instance by having the LB return a
|
||||
// serverlist with non-existent backends after having initially returned a
|
||||
// valid one.
|
||||
//
|
||||
// Findings from end to end testing to be covered here:
|
||||
// - Handling of LB servers restart, including reconnection after backing-off
|
||||
// retries.
|
||||
// - Destruction of load balanced channel (and therefore of grpclb instance)
|
||||
// while:
|
||||
// 1) the internal LB call is still active. This should work by virtue
|
||||
// of the weak reference the LB call holds. The call should be terminated as
|
||||
// part of the grpclb shutdown process.
|
||||
// 2) the retry timer is active. Again, the weak reference it holds should
|
||||
// prevent a premature call to \a glb_destroy.
|
||||
// - Restart of backend servers with no changes to serverlist. This exercises
|
||||
// the RR handover mechanism.
