## Abstract

A test apparatus comprising functional entities, FEs, which are assigned to a selected test case, TC, of a test case pool, TCP, by shifting a test case item, TCI, representing the selected test case, TC, to functional block items, FBIs, representing functional entities, FEs.

## Claims

### Claim 1

A test apparatus comprising:
functional entities, FEs, which are assigned to a selected test case, TC, of a test case pool, TCP, by dragging a test case item, TCI, representing the selected test case, TC, to functional block items, FBIs, representing the respective functional entities, Fes, and by dropping the dragged test case item, TCI, on the functional block items, FBIs; and
a processing unit adapted to compare test capabilities required by the selected test case, TC, as indicated by its associated test case item, TCI, with test capabilities offered by the functional entities, FEs, assigned to the selected test case, TC, as indicated by the functional block items, FBIs, of the assigned functional entities, FEs;
wherein, if the test capabilities offered by the functional entities, FEs, assigned to the selected test case, TC, match the test capabilities required by the selected test case, TC, a test procedure using the assigned functional entities, FEs, for the test case, TC, is initiated in response to an input command if no further test cases, TCs, are selected from the test case pool, TCP; and
wherein, if there is no matching of test capabilities, the user is informed that the test capabilities of the test apparatus are not sufficient for the selected test case, TC, and an already running test case procedure is deactivated to get more available resources within the test apparatus for the selected test case, TC, based on a drag and drop operation of the user for test case deactivation.

### Claim 2 (depends on 1)

The test apparatus according to claim 1 wherein the functional entities, FEs, of said test apparatus comprise hardware entities and/or software entities represented by associated functional block items, FBIs, displayed on a graphical user interface, GUI, of said test apparatus.

### Claim 3 (depends on 1)

The test apparatus according to claim 1 wherein the functional entities, FEs, of said test apparatus are controlled by a controller of said test apparatus.

### Claim 4 (depends on 3)

The test apparatus according to claim 3 wherein the functional entities, FEs, of said test apparatus represented by associated functional block items, FBIs, displayed on a graphical user interface, GUI, of said test apparatus are connectable by said controller of said test apparatus in response to commands received via the graphical user interface, GUI.

### Claim 5 (depends on 1)

The test apparatus according to claim 1 wherein the test apparatus is adapted to test at least one user equipment, UE, device.

### Claim 6 (depends on 1)

The test apparatus according to claim 1 wherein the functional entities, FEs, of said test apparatus represented by associated functional block items, FBIs, comprise
an RF Front End,
an AF/IQ/SPDif Front end,
an RF Converter,
a Signaling Unit,
a Measurement Unit,
a Signal Generator,
a Processing Unit,
a Data Application Unit,
an Audio Unit and/or
a Sample Bus.

### Claim 7 (depends on 1)

The test apparatus according to claim 1 wherein the test cases, TCs, of said test case pool, TCP, comprise
RF conformance test cases,
audio quality test cases,
handover test cases,
end-to-end communication test cases,
coexistence test cases,
user experience test cases, and
emergency service test cases.

### Claim 8

A method for testing devices by means of a test apparatus,
wherein functional entities, FEs, of said test apparatus are assigned to a selected test case, TC, of a test case pool, TCP, by dragging a test case item, TCI, representing the selected test case, TC, to functional block items, FBIs, representing the functional entities, Fes, and by dropping the dragged test case item, TCI, on the functional block items, FBIs; and
wherein test capabilities required by the selected test case, TC, as indicated by its associated test case item, TCI, are compared with test capabilities offered by the functional entities, FEs, assigned to the selected test case, TC, as indicated by the functional block items, FBIs, of the assigned functional entities, FEs;
wherein, if the test capabilities offered by the functional entities, FEs, assigned to the selected test case, TC, match the test capabilities required by the selected test case, TC, a test procedure using the assigned functional entities, FEs, for the test case, TC, is initiated in response to an input command if no further test cases, TCs, are selected from the test case pool, TCP; and
wherein, if there is no matching of test capabilities, the user is informed that the test capabilities of the test apparatus are not sufficient for the selected test case and an already running test case procedure is deactivated to get more available resources within the test apparatus for the selected test case, based on a drag and drop operation of the user for test case deactivation.

### Claim 9 (depends on 8)

The method according to claim 8
wherein the test case, TC, is selected from a test case pool, TCP, by moving a pointer to the displayed test case item, TCI, representing said test case, TC, or by touching the displayed test case item, TCI, representing said test case, TC.
