How to use different parameter combinations to generate a separate testcase function (Python)

There is a problem when using selenium2 python for automated testing, and after writing a testcase report, there is a case execution status record. So we write a login function of the automation use cases, write only one case is obviously not possible, the test case to meet his coverage, so we need to write multiple use cases. But for the same function, our use-case script shows that only the input parameter values are different, and the other operations are the same.

This is a use case to write a test_case_login () script, but we want to record the execution status of each of the cases separately in the report, not to write multiple duplicate methods. such as: Test_case_login_1 () test_case_login_2 () Test_case_login_3 () when the execution is complete, the test report is generated using unittest, and the execution status is recorded for each test_case. But the code is too redundant and the content is too cumbersome. Maybe at this point we can just write a test case and use inline loops, but one problem is that one of them is wrong and it's hard to see it in the test results. The crux of the problem is whether there is a way to generate the corresponding test case based on the different combinations of input parameters. For example, I have 5 groups of data, there should be 5 test_case_login, above I have said that it is not suitable to write 5 test_case_login directly, then what should be done? One possible idea is not to use UnitTest. TestCase the method of the Test_ member function in this class box, instead of writing runtest This member function, there will be some extra work, and it does not look so "smart" if the purpose is to have the framework automatically call Test_case

The natural idea is to use setattr to add member functions to an existing testcase class • To make this approach work, you need to use the static method of the class to generate a member function of the decorate class and return the function to a test function object. Register this call to the Add Test member function somewhere (just before you actually do it, you can do it automatically in the module or you can call it manually) the use case data is as follows:

case_id	Summary	Login_name	Login_password	Remark
case_0001	Authentication with NULL user name		111111	Please enter user name
case_0002	Authentication with null password	Admin		Please enter your password
case_0003	Bad user name Verification	Lidje	111111	Sorry, your campus access account and password can not be verified by the system
case_0004	Bad password Authentication	Admin	Ddsss	Sorry, your campus access account and password can not be verified by the system
case_0005	Correct user name, password verification	Admin	111111	Login successful

The code is as follows:
