8.3 Message transmission requirements

Clear information interaction specifications should be formulated, mainly including the following aspects.

a) Message communication layer protocol

The message communication protocol is used to describe the protocol and method of message transmission between systems at the communication level, including network protocol, communication

Routing, sender and receiver, identification and reliability, etc.

b) Message communication method

There are generally two ways of message communication.

1) The synchronization method is "Request-Response" type, which is mainly used in real-time scenarios, such as pulling data in real time, or

Perform remote calls. If it is to perform a remote call, the application layer is usually required to take measures to maintain the transaction of both parties/

Data consistency.

2) The asynchronous mode is "Request/OneWay", and the message is sent to the other party through the communication middleware, and the sender only gets

Take the communication response. The API of the communication middleware is usually required to provide transaction functions and ensure delivery (the receiver correctly receives

Collect and process).

c) Message body format specification

Common message body formats such as string segmentation, XML, JSON, etc.

9.1 Overview

Interoperability interface testing is generally to determine whether the interface meets or meets the corresponding specifications by testing the input and output parameters in different scenarios

And product requirements, and its test requirements include but are not limited to.

a) Check the process of data exchange, transmission and control management, as well as mutual logical dependence;

b) Check the correctness of the interface parameter transfer, the correctness of the interface function realization, and the correctness of the output result;

c) Check the completeness and rationality of fault-tolerant processing of various abnormal situations.

9.2 Business function test

The interface test scenarios and test environment should be designed according to the discrete or process industry characteristics of the system to be tested. The test scenario should be at least

Covers production management information exchange scenes, quality management information exchange scenes, inventory management information exchange scenes, maintenance management information exchange scenes,

And other required scenes.

It should address the requirements of data exchange service functions such as information transmission, information processing, and business representation for data exchange, as well as the message communication layer protocol,

Message communication method (synchronous/asynchronous), interface realization method (active/passive) and other message transmission requirements, and develop different interface tests

Strategy.

According to business logic, multi-interface procedural testing should be conducted for different business scenarios.

9.3 Boundary and anomaly testing

According to the interface parameters provided in the design document, the parameters should be passed in normally to test whether the correct result is returned.

The verification of abnormal conditions by the interface shall be verified. When the parameters are not entered according to the interface requirements, test the handling of the interface. Common differences

Common situations include whether the parameter is required, whether the parameter length/parameter type meets the requirements, etc.

When there are multiple parameters in the interface, and there is a logical relationship between the parameters, all possible normal and

Abnormal combination situation.

9.4 Performance and safety testing

Interface performance test content generally includes response time, throughput, concurrency, server resource utilization, etc.

The interface security test content generally includes checking whether the interface verification can be bypassed, checking whether the identity authorization can be bypassed, and checking whether the parameters are encrypted.

Check the complexity of the password.
