func RoamDiagnostics ¶
RoamDiagnostics executes the test case
Bring an AP up, connect to it, set the attenuation, and vary a second AP around the same RSSI as the first AP. Perform a scan after every change in attenuation and observe when the device roams between APs. Record all roam events in a file for analysis. The purpose of this diagnostic is to capture the stickiness of the device's roam algorithm. For example, the stickier the algorithm, the more skewed toward higher RSSI differentials (between current and target AP) the distribution of roams in the output files will be. This is not necessarily a good thing as it's important for a device to be able to move between APs when it needs to. Therefore, we use RoamNatural in conjunction with this test to ensure that normal roam behavior is not broken.
func RoamNatural ¶
RoamNatural executes the test case
Bring up two APs, connect, vary attenuation as if the device is moving between the two APs (i.e. the signal gets weaker on one and stronger on the other until the first one cannot be seen anymore). At some point before the first AP is torn down, the device should have roamed to the second AP. If it doesn't there will be an association failure, which we can then log and write to a file. Ideally, there would be no association failures and a roam every time we expected one. Realistically, RSSI can vary quite widely, and we can't expect to see a good roam signal on every scan even where there should be one. This test is used to validity check that "normal" roaming behavior is not broken by any roaming algorithm changes. A couple failed associations is acceptable, but any more than that is a good indication that roaming has become too sticky.
