"Introduction to interface testing" punch in day08: can you save all parameters to excel for test data?

Ideas ： You need to encapsulate the data , In a better way , Store data in a data storage file , In this way, the code can find the corresponding parameters by itself , Then call the test framework to execute the test process , Then return the expectation through automatic comparison , Check whether the test results are correct .

Two benefits .1、 Nobody is on duty , Save time and energy .2、 Automatically detect the return value , Improve test efficiency .

How to select test data

1、 First , You first need to define a parameter storage format , For now ,Excel It is the most used tool in designing test cases , Then we can also use Excel Store files as your own parameters .

But before we do it , You should also think of , Your parameter file type will not be unchanging Excel, In the future, you may also use parameter files in other formats , So at the beginning, you should also consider the extensibility of parameter classes , In this way, you don't need every additional parameter file storage format , Just write a parameter class , To complete the selection and call of parameters .

Thinking is through unified abstraction , Establish a common way to process data . You can design and use simple factory design patterns , In this way, if there is another parameter storage type , Add a corresponding processing class , This is very convenient for you to expand quickly , It can also provide a unified data processing mode once and for all .
