In a test automation method and test system for a user end apparatus that
can be communicatively connected with a test automation apparatus, at
least one data processing unit and a non-volatile memory for storage of a
test workflow program as well as a first external interface and a second
external interface are provided. The user end apparatus has at least one
control unit, a non-volatile memory and an external interface. The user
end apparatus is protected by a security housing and has an external
interface that can be placed in communication with the special second
external interface of the test automation apparatus. By loading release
software, the user end apparatus is programmed to generate test output
signals and to supply these to the external interface. The data
processing unit of the test automation apparatus is programmed via the
test workflow program for execution of at least one routine for at least
one test case and is connected with the special interface via which the
test input signals (simulated in the test case) are transmitted to the
internal interface of the user end apparatus.
