Abstract

A communication protocol testing method, a tested device and a testing platform. The method includes: the tested device and the reference device execute a communication protocol, a message sent and/or received during execution of the communication protocol serving as a first message, and the first message being encapsulated in a data encapsulation format of the communication protocol; the tested device encapsulates a part of data or all the data in the first message and/or known data of the tested device according to a unified data encapsulation format to generate a second message; and the testing platform acquires the second message, parses the acquired second message according to the unified data encapsulation format to obtain a part of data or all the data in the second message, executes testing items, and outputs testing results, thereby completing the test.

First claim

The invention claimed is:

1. A method for testing a communication protocol, involving a testing platform, a tested device and a reference device, for detecting an execution situation of the tested device when the communication protocol is executed between the tested device and the reference device, the method comprising:
executing, by the tested device and the reference device, the communication protocol, wherein a message transmitted and/or received by the tested device when executing the communication protocol is referred to as a first message, and the first message is encapsulated in a data encapsulation format of the communication protocol;
encapsulating, by the tested device, a part or all of data in the first message according to a unified data encapsulation format to generate a second message, or encapsulating, by the tested device, a part or all of data in the first message and data known to the tested device according to a unified data encapsulation format to generate a second message; and
obtaining the second message by the testing platform, wherein the part or all of data in the first message comprises data obtained by the tested device by parsing the received first message according to the communication protocol and/or data used by the tested device for constructing the transmitted first message;
parsing, by the testing platform, the obtained second message according to the unified data encapsulation format to obtain a part or all of data in the second message; and
executing, by the testing platform, testing items according to the part or all of data in the second message obtained by the parsing, and outputting, by the testing platform, a testing result to complete the testing.

2. The method according to claim 1 , wherein the method further involves an auxiliary device, the auxiliary device participates in the process of executing the communication protocol, a message transmitted and/or received by the auxiliary device when executing the communication protocol is referred to as a third message, and the third message is encapsulated in a data encapsulation format of the communication protocol;
the auxiliary device encapsulates a part or all of data in the third message to the unified data encapsulation format to generate a fourth message, the testing platform obtains the fourth message, or the auxiliary device encapsulates a part or all of data in the third message and data known to the auxiliary device according to the unified data encapsulation format to generate a fourth message; and
the testing platform obtains the fourth message, and the part or all of data in the third message comprises data obtained by the auxiliary device by parsing the received third message according to the communication protocol and/or data used by the auxiliary device for constructing the transmitted third message;
the testing platform parses the obtained fourth message according to the unified data encapsulation format to obtain a part or all of data in the fourth message, and uses the obtained part or all of data in the fourth message to assist in the testing; and
the using of the part or all of data in the fourth message by the testing platform to assist in the testing comprises: comparing, by the testing platform, data in data of the fourth message obtained by the parsing with corresponding data in data of the second message obtained by the parsing, and obtaining a comparison result by the testing platform.

3. The method according to claim 2 , wherein the unified data encapsulation format is a data encapsulation format supported by the testing platform, and the unified data encapsulation format is applicable in performing the testing for each of a plurality of different communication protocols.

4. The method according to claim 3 , wherein the unified data encapsulation format comprises a payload;
the payload comprises data elements defined therein, and each of the data elements in the payload is encapsulated in a data element encapsulation format comprising three fields, which comprise an element type, an element length and an element information; and
the element type identifies a specific data, or the element type identifies all data needed by a testing item.

5. The method according to claim 4 , wherein the data element defined in the payload further comprises an original message, which is the first message or the third message.

6. The method according to claim 5 , wherein the unified data encapsulation format further comprises a head, the head comprises a version field and a length field of the unified data encapsulation format, and the head further comprises one or more of a device role field, a receiving and transmitting identification field, a manufacturer identification field, a protocol type field, a grouping sequence number field, a fragmenting sequence number field, a fragmenting identification field and an extended field.

7. The method according to claim 2 , wherein the obtaining the fourth message by the testing platform comprises transmitting, by the tested device, the fourth message to the testing platform in an online manner, or importing, by the tested device, the fourth message to the testing platform in a file exporting manner.

8. The method according to claim 2 , wherein the auxiliary device is integrated into the testing platform.

9. The method according to claim 1 , wherein a message transmitted and/or received by the reference device when a communication protocol is executed between the reference device and the tested device is referred to as a fifth message, and the fifth message is encapsulated in a data encapsulation format of the communication protocol;
the reference device encapsulates a part or all of data in the fifth message according to a unified data encapsulation format to generate a sixth message, or the reference device encapsulates a part or all of data in the third message and data known to the reference device according to a unified data encapsulation format to generate a sixth message;
the testing platform obtains the sixth message, and the part or all of data in the fifth message comprises data obtained by the reference device by parsing the received fifth message according to the communication protocol and/or data used by the reference device for constructing the transmitted fifth message;
the testing platform parses the obtained sixth message according to the unified data encapsulation format to obtain a part or all of data in the sixth message, and uses the obtained part or all of data in the sixth message to assist in the testing; and
the using of the part or all of data in the sixth message by the testing platform to assist in the testing comprises: comparing, by the testing platform, data in data of the sixth message obtained by the parsing with corresponding data in data of the second message obtained by the parsing, and obtaining a comparison result by the testing platform.

10. The method according to claim 9 , wherein the obtaining the sixth message by the testing platform comprises transmitting, by the tested device, the sixth message to the testing platform in an online manner, or importing, by the tested device, the sixth message to the testing platform in a file exporting manner.
