Abstract

A testing system that provides a separate set of virtualization container probes for each of at least a subset of devices that is under testing can perform Wifi Layer 2 and Wifi Layer 3 tests in a manner that minimizes or avoids wireless interference is disclosed.

Claims

1. A testing system for testing a plurality of devices, the testing system comprising:

a plurality of test station slots, wherein;

each test station slot of the plurality of test station slots is configured to receive and connect to a corresponding wireless device of a plurality of wireless devices to be tested; and

each test station slot of the plurality of test station slots is configured to use a shared wireless frequency channel for performing one or more wireless tests on each test station slot'"'"'s corresponding installed wireless device to be tested; and

at least one resource control server, wherein;

the at least one resource control server is configured to lock the shared wireless frequency channel;

a respective test station slot of the plurality of test station slots sends a request to the at least one resource control server for a lock on the respective test station slot'"'"'s shared wireless frequency channel when the respective test station slot needs to perform a wireless test on the respective test station slot'"'"'s corresponding installed wireless device to be tested; and

the at least one resource control server is configured to grant the request for the lock on the respective test station slot'"'"'s shared wireless frequency channel based on a predetermined set of criteria.

2. The testing system of claim 1, wherein the predetermined set of criteria comprises:

granting a lock on a shared wireless frequency channel for performing Layer 2 wireless tests only if all previously granted locks on the shared wireless frequency channel for performing Layer 3 wireless tests are released.

3. The testing system of claim 1, wherein the predetermined set of criteria comprises:

granting a lock on a share wireless frequency channel for performing Layer 3 wireless tests only if all previously granted locks on the shared wireless frequency channel for performing any wireless tests are released.

4. The testing system of claim 1, wherein the predetermined set of criteria comprises:

granting a lock on a shared wireless frequency channel for performing wireless tests based on a first-come-first-served basis.

5. The testing system of claim 1, wherein the predetermined set of criteria comprises:

granting a lock on a shared wireless frequency channel for performing wireless tests based on business rules.

6. The testing system of claim 1, further comprises a test control computer that is associated with the at least one resource control server.

7. A system comprising:

a plurality of test station slots, each test station slot of the plurality of test station slots configured to host a wireless device and assignable to a shared frequency channel to test the wireless device; and

a resource control server configured to allocate wireless resource locks to the plurality of test station slots,

wherein at least one test station slot of the plurality of test station slots is configured to request from the resource control server a wireless resource lock on the shared frequency channel assigned to the test station slot,

wherein the resource control server is configured to determine an availability of the assigned shared frequency channel and provide a response based on the availability, and

wherein the resource control server is further configured to grant the request for the lock on the respective test station slot'"'"'s shared wireless frequency channel based on a predetermined set of criteria.

8. The system of claim 7, wherein the resource control server is configured to provide the response by granting the requested wireless resource lock if the assigned shared frequency channel is available, and the at least one test station slot of the plurality of test station slots is configured to respond to the granted wireless resource lock by performing a test on the wireless device.

9. The system of claim 7, wherein the resource control server is configured to provide the response by denying the requested wireless resource lock if the assigned shared frequency channel is not available, and the at least one test station slot of the plurality of test station slots is configured to respond to the denied wireless resource lock by deferring a test on the wireless device.

10. The system of claim 7, wherein the request from the at least one test station slot of the plurality of test station slots includes information about a type of test to be performed and the availability of the shared frequency channel is determined responsive to the type of testing to be performed.

11. The system of claim 10, wherein the type of test to be performed comprises an OSI Layer 2 test or an OSI Layer 3 test.

12. The system of claim 10, wherein the type of test to be performed comprises a DOCSIS speed test.

13. The system of claim 7, wherein the availability of the requested shared frequency channel is determined responsive to requests received from other test station slots of the plurality of test station slots.
