The second embodiment proposed by the present invention:

The third embodiment proposed by the present invention:

A method for realizing automatic test of Ethernet bus data comprises the following steps: automated testing of ethernet bus data.

Testing of ethernet bus data is typically accomplished in multiple steps, each of which is combined into a single test sequence. The establishment of the test sequence is the focus of the present invention. Firstly, professional manual operation flow needs to be abstracted into actions, namely, the whole test process is decomposed into concrete actions, and then each action is packaged into a control program (TP).

TPs are also classified into two types, one being an individually executable application program (EXE program) and the other being a type of dynamic library (DLL). The programming of the TP may be dependent on programmed commands from the instrument or on the drive of the instrument itself. The TP typically has functions of instrument control, test data transfer into a database, state retention, and reading. And each TP must reserve the control interface and its location information in the sequence.

The state settings of each TP are separate from the TP's running program. The state setting is to be performed before the sequence runs. The running program of the TP is connected with the state setting program of the TP through a state file. The state parameters set by the state setting interface are stored in a built file, and when the TP runs, the state information is read from the file, so that the instrument control is performed according to the state information.

1) The ethernet test is classified into the following four categories according to the purpose of the test:

(1) conformance testing (Conformance Test)

For verifying whether the implementation of the relevant protocol of the device under test complies with the protocol specification. Interoperability or compatibility can only be achieved between devices that follow the same network protocol.

(2) Function Test (Functional Test)

For verifying that the functions nominally supported by the product are implemented correctly.

(3) Performance Test (Performance Test)

Generally considered a stress test, with the aim of observing the behaviour of the device under traffic stress.

(4) Passive Test (Passive Test)

Unlike active testing, it does not actively send messages to the device under test, and like protocol analysis, observes the protocol running process in a true running state.

2) The main program can control the operation of each TP through the position information and the control interface of the TP. At least one thread exists in the main program, the thread controls the operation of each TP, an interrupt function exists in the thread, and the whole sequence can be flexibly controlled through the position information of the TP to carry out circulation, pause, pre-judgment and the like. The communication between the main thread and the TP is realized through a database, and the database uses Access or Mysql. The ethernet TP has: traffic monitoring, traffic generation, data capture, protocol decode analysis, RFC2544 testing, RFC3393 testing, Y.1564 testing, EtherBERT testing, loopback, data playback, network topology testing, Ping, Tracert, FTP/HTTP download testing, IPv4 testing, IPv6 testing, VLAN, MPLS support.

The above description is only a preferred embodiment of the present application and is not intended to limit the present application, and various modifications and changes may be made by those skilled in the art. Any modification, equivalent replacement, improvement and the like made within the spirit and principle of the present application shall be included in the protection scope of the present application.
