(3) the automatic measurement and control unit completes the sending of the sending packet, the receiving and analysis of the receiving packet and the generation of the test report according to the test flow configuration content in the database.
4. The intelligent testing method for the digital satellite embedded simulation platform according to claim 3, wherein the working process of the initial parameter configuration unit is as follows:
before testing, information flow configuration and federal configuration are carried out through an initial parameter configuration unit, and configuration results are stored in a database;
and configuring a test flow according to the required test content, generating a test execution flow statement, and storing the test execution flow statement in a database.
5. The intelligent test method for the digital satellite embedded simulation platform according to claim 4, wherein the automatic measurement and control unit comprises a monitor module and a process control module;
the working process of the automatic measurement and control unit is as follows:
the monitoring module sends an instruction for executing a test execution flow statement to the flow control module, and displays the test progress and the test execution flow statement execution result in real time;
the flow control module receives the instruction sent by the monitoring and displaying module and executes the test execution flow statement;
for the data related to the test execution flow statement, the flow control module acquires corresponding sending packet data, assembles the sending packet and sends the sending packet to the monitoring and displaying module; for the sending statements related in the test execution flow statements, the flow control module sends the sending statement assembly sending packages to the monitoring module;
the monitoring module sends the sending packet to the tested device, receives the receiving packet from the tested device and returns the receiving packet and the test execution flow statement execution result to the flow control module;
the flow control module receives the return packet returned by the monitoring module and the execution result of the test execution flow statement, and compares and archives the data;
the monitoring and displaying module reads the archived data of the flow control module and automatically generates a test report.
6. The intelligent testing method of the digital satellite embedded simulation platform as claimed in claim 5, wherein in the process of executing the test execution flow statements by the flow control module, for the statements related to transmission, the flow control module further obtains the comparison packet data, assembles the transmission packet and transmits the transmission packet to the monitor module.
