The pursuit of agile development has led many teams to adopt a pyramid testing strategy. The pyramid testing strategy requires automated testing at 3 different levels, as shown in the figure:
Automated testing pyramid strategy
The pyramid shown in the figure above requires automated testing to be carried out from 3 different levels. The bottom unit test accounts for the largest percentage of automated testing, followed by interface testing and U testing. Putting the focus of automated testing on the unit testing and interface testing stages will help speed up the overall development progress of the project and reduce the cost of later development and testing. Next, explain the three parts of the pyramid model.
(1) Unit test
Unit testing requires testing each functional module (function, class method) during development, such as testing whether a certain function is operating normally as expected. White box testing is usually used in unit testing, which mainly tests the internal logic structure of the code.
(2) Interface test
Interface testing requires testing of data transmission and database performance to ensure the integrity of data transmission and processing. The complete operation of the interface function plays an important role in the expansion, upgrade and maintenance of the entire project. Interface testing is usually carried out by a combination of black box testing and white box testing.
(3) UI test
UI testing focuses on user experience, and all functions of the software are displayed to users through this layer, so UI testing is also very important. Since the UI interface is based on the ultimate user experience, automated testing is not 100% used in UI testing, which requires manual operation to determine the ease of use of the UI interface.
