Claim 4

Testing apparatus for testing and handling a multiplicity of devices comprising: (2.1) a test executor provided for controlling operation of the individual test steps, (2.2) at least one test adapter for receiving at least one device to be tested, (2.3) said devices arranged in plural entities that are logical and/or physical, each entity being hierarchically arranged among all said entities and representing a discrete category, and wherein said test executor includes a hierarchical operating level assigned to each of said physical or logical entities, and each said hierarchical operating level, except a lowest hierarchical operating level, including (2.4) at least one test level controller set up to perform at least the following sequence of operating steps: (2.4.1) A call to a lower hierarchical operating level, (2.4.2) a return from said lower operating level, and (2.4.3) a post-activity sequence of tasks, and wherein (2.5) the lowest hierarchical operating level is processed by at least one device test processor provided for the test of parameters of individual devices.

Claim 5

Testing apparatus according to claim 1, wherein said call to a lower hierarchical level is made to the next lower hierarchical level.

Claim 6

Testing apparatus according to claim 1 with at least three hierarchical operating levels, wherein the test level controller assigned to the highest hierarchical operating level performs a call to the test level controller assigned to the next lower hierarchical operating level, and so on until operation arrives at the lowest hierarchical operating level to which said device test processor is assigned.

Claim 7

Testing apparatus according to claim 4, wherein operation returns from said device test processor to the test level controller assigned to the next higher hierarchical operating level, and so on.

Claim 8

Testing apparatus according to claim 1, wherein the test level controller includes, in its pre-activity sequence of tasks, an instruction to skip the call to a lower hierarchical operating level if an appropriate indicator is set.

Claim 9

Testing apparatus according to claim 2, wherein the test level controller includes, in its post-activity sequence of tasks, an instruction to return to its pre-activity sequence of tasks if an appropriate indicator is set.

Claim 10

Testing apparatus according to claim 2, wherein the test level controller includes, in its post-activity sequence of tasks, an instruction to continue operation at the same hierarchical level of operations.

Claim 11

Testing apparatus according to claim 1 including at least one handling tool for processing said physical or logical entities.

Claim 12

Testing apparatus according to claim 1, wherein the pre-activity sequence of tasks includes at least one of the following tasks: (10.1) Input of process data, (10.2) command input, (10.3) operation of at least one handling tool.

Claim 13

Testing apparatus according to claim 2, wherein the post-activity sequence of tasks includes at least one of the following actions: (11.1) data logging, (1.1.2) operation of at least one handling tool.
