Gordon does not pick up all available devices #117
Description
Discussed in #116
In my setup all devices are in one pool, e.g. with PoolingStrategy.SinglePool or PoolingStrategy.Manual (all devices manually added to a single pool) - tried both options to see if it makes any difference.
The scenarios I described above is that there are always devices (marked as NOT PICKED above) which are completely ignored during the whole test run. I have around 600 tests. They run (one test per device) only on the devices marked above as picked.
My expectation would be that all devices in the pool will be at some point used during the whole run. Running each test once on any of those devices.
More clarification: before the test starts I see in the log the installation of the app APK and test APK, already there the ignored devices are consistently not shown. No timeout message, etc. I also increased the installation timeout but no change.

In the log the devices: real-device-1, host-b:8559 do not show nor are those devices used.
As I said, if I turn off/disconnect the ignored devices another 2 devices will be not picked at all. In the example shown in the log if I disconnect real-device-1, real-device-2 will not be picked. If I turn off host-b:8559, host-b:8557 will not be picked by the test at all.
It seams strange. But it somehow seems as if the devices get clustered by type (real/emulator) and host where they run. The behavior described above seems to then apply for each cluster which has more than 1 device:
If I have: real-device-1, emulator-1, host-a:7555, host-b:8555 all devices get picked.
If I have: real-device-1, real-device-2, emulator-1, host-a:7555, host-b:8555 => real-device-1 does not get picked.
If I have: real-device-1, real-device-2, real-device-3, emulator-1, host-a:7555, host-b:8555 => real-device-1 does not get picked.
If I have: real-device-1, emulator-1, host-a:7555, host-b:8555, host-b:8557 => host-b:8557 does not get picked.
If I have: real-device-1, emulator-1, host-a:7555, host-b:8555, host-b:8557, host-b:8559 => host-b:8559 does not get picked.
Weird right?
