1. What is the interface testing
Interface test is a test to test system components built interface, an interface between the primary interfaces, system internal test individual submodules between the detection system and external test system. The focus of the test is used to check the correctness of the interface parameters passed, the interface functions to achieve correctness, completeness and reasonableness as well as a variety of fault-tolerant processing.
2. Why do interface testing
a. Pre-test
Interface test does not depend on the progress of the development of the front of the server-side design interface documentation can begin testing, we can make the requirements phase test plan, test environment is configured, each submission interface can be tested. Interface testing target is to complete all the front-end interface test prior to start of the test, so you can throw the problem as soon as possible, to save testing time
b. to reduce test costs and increase test efficiency
First, closer to the underlying interface test, a large number of calculations are performed on the server side interface testing easier to find the underlying problem, calculated in accordance with the data model, a bug can be purchased to the underlying cause upper bug about 8, whereby the development can save more test time
Second, the interface testing is automated and continuous integration, code changes from time to time to automatically execute test cases to improve test efficiency, saving the cost of regression testing
Third, the interface may be isolated from the environment test, not because of changes in the test environment generated labor costs, save test time
c. Test results are more reliable
First, the interface test is the perspective of users of the system interface for continuous detection of a comprehensive university, secondly, interface testing of smaller size than the functional test, functional test coverage can not cover the test point, finally, is the continuous integration interface testing the return to a more comprehensive coverage of
