Postman interface test

One 、 Interface classification

1. External interface ： The interface between the tested system and the external system
2. Internal interface ： The interface between modules in the tested system

Two 、 Key points of interface test

1. Check the correctness of interface parameters
2. Correctness of interface functions
3. Correctness of output results
4. Fault tolerant handling of abnormal scenarios
5. Access control

3、 ... and 、 Interface test process

1. Get api Interface document （ Get from the developer or grab the package ）, Familiar with business interface 、 Address of the interface 、 Authentication method 、 Enter the reference 、 The ginseng 、 Error codes and other special requirements .
2. Review the interface and test case writing
   Write ideas ：
   Example ： Enter the correct input parameters 、 The interface returns to normal
   Counter example ：
   Counterexample of authentication ： The authentication code is empty 、 error 、 Be overdue ...
   Parameter counter example ： Whether the parameter is required to verify 、 Exception verification of parameters 、 Error code overwrite ...
   Other scenarios ： Interface blacklist 、 Interface call times limit 、 Paging scenario test （ Negative pages 、0、1、5、 10…100）
3. Using interface test tools Postman、Jemeter Perform interface tests
4. Postman+newman+jenkins+git Implementing continuous integration .（ Output reports and emails ）

Four 、Postman Interface testing tool

1. Two tool systems ：Postman+newman+jenkins+git、Jemeter+Ant+jenkins+git
2. Postman The workbench
