This article is about what interface testing refers to in computers. The editor thinks it is very practical, so share it with you as a reference and follow the editor to have a look.

Interface testing is a kind of test to test the interface between system components. Interface testing is mainly used to detect the interaction points between the external system and the system as well as between the internal subsystems. The focus of the test is to check the correctness of the transmission of interface parameters, the correctness of the implementation of interface functions, the correctness of the output results, and the integrity and rationality of fault-tolerant processing for all kinds of abnormal cases.

Interface testing is a test of the interface between the components of the test system, which is mainly used to test the interface between the system and other external systems, as well as the interface between the sub-modules within the system. The focus of the test is to check the correctness of the transmission of interface parameters, the correctness of the implementation of interface functions, the correctness of the output results, and the integrity and rationality of fault-tolerant processing for all kinds of abnormal cases.

The classification of software interfaces generally has the following situations:

1) system-to-system calls, such as Wechat provides a unified external interface to users, programmers call the interface to complete Wechat-based Mini Program, etc.

2) the invocation of upper layer services to lower layer services in the same system, for example, a software program is generally divided into presentation layer, business layer and data layer. The presentation layer calls the interface of the business layer to complete its own work. And the business layer will call the interface of the data layer to implement the corresponding business and so on.

Its core is to ensure the correctness and stability of the system, and its importance is mainly reflected in the following aspects:

(1) bug can be found in advance, which accords with the idea of quality control moving forward.

(2) Interface testing is low-cost and cost-effective, because interface testing can be automated and continuously integrated.

(3) the interface test comprehensively detects the system interface from the user's point of view. In the actual project, the interface test will cover a certain degree of business logic

Scope of use:

Interface testing is generally used for interactive development between multiple systems, or for the development of application systems with multiple subsystems. Interface testing is suitable for the underlying framework systems and central service systems that provide services for other systems, mainly testing the interfaces provided by these systems to the outside to verify their correctness and stability. Interface testing is also applicable to the service layer interface in an upper layer system, and the higher the level, the more difficult it is to test. The application of interface testing in Taobao is a bottom-up development process.

Interface testing is implemented under the framework of multi-system and multi-platform, and has a very efficient cost-benefit ratio. Interface testing naturally brings efficient defect monitoring and quality supervision capabilities to highly complex platforms. The more complex the platform is and the larger the system is, the more obvious the effect of interface testing is.

The purpose of interface testing is to test the interface, especially those external interfaces associated with the system. The focus of the test is to check the data exchange, transfer and control management process, as well as the number of processing. External interface testing is generally treated as a system test.

Not all teams can test in an isolated test environment, which makes it difficult to test external interfaces. We should ensure that we coordinate with the relevant organizations early and determine the plan for external interface testing. Sometimes the relevant organization only reviews the data manually and statically and does not actually test it with it. All of these increase the risks encountered in the actual test execution, but sometimes they can be avoided.
