Interface test

One 、 Basic definition of interface test

Interface test is a test to test the interface between system components . The interface test 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 exchange of data , Transfer and control the management process , And the mutual logical dependence between systems （ From baidu baike ）

In my own words, for the interface , After giving a certain parameter, the interface can return the corresponding result .

Two 、 What does the interface test mainly measure

So interface testing mainly includes ： database , cache , Tests outside the front end such as message queues .

for instance , Take the action of paying as an interface , So what do you need to pay ： Need money ！

What are the conditions for needing money , How much does it cost? , What currency do you need , How many times do I have to pay ？

So interface testing mainly tests ： function , performance , Safety, etc

3、 ... and 、 How to test the interface test

There are two kinds of interfaces , One refers to the interface provided by the back end , One refers to the interface provided by the front end ,

The interface provided by the front end is what we usually access http Interface , Tools can be used to test this interface POSTMAN To test .

The interface provided by the backend , There is no interface , The way to test this interface is to write code to directly call the developed interface .

Four 、 Points to pay attention to in interface testing

1、 Idempotent test

What is idempotent test ？ I've been hearing about idempotent testing , I checked recently , Idempotent test .

When learning power in mathematics, it is described like this ,a^m pronounce as a Of m The next power , Yiba a multiply continuously m Time .

So for interface testing , Idempotent means that any number of executions have the same impact as one execution , Don't worry that repeated execution will change the system

How to do idempotent test ？

for instance ： Repeat transaction

2、 Asset loss point

3、 Big data test

In addition, Amway provides you with a very useful interface testing tool apipost, Meet all interface debugging work and generate interface documents of various styles .  Suitable for novice Xiaobai , The documentation is clear, too .
