Sqlserver generates consecutive numbers and operates according to the specified numbers The running method can be divided into running in the Python shell or running in the system shell: lang:python > import doctest > doctest.testfile( 'example.txt')īash / cmd.exe: $ python -m doctest -v example.txt > from test import multiply > multiply(2,3) 6 > multiply( 'baka~',3) 'baka~baka~baka~'Īlmost the same format.

If you do not want (or cannot) write test cases into your source code, you can also use a separate text file to save the test cases. The output is basically the same as above. For other cases where the _main_ function is used, you can also start the test from the command line: $ python -m doctest unnecessary_math.py $ python -m doctest -v unnecessary_math.py Here -m refers to a module, and -v equivalent to verbose=True. This is a good way for pure container-type module files-only import for normal use, and run the file directly for testing. The way to start the test in the above example is to call the doctest.testmod() function in the _main_ function. If you do not write, then nothing will be output at runtime, unless you test fail.Įxample run output is: Trying: multiply( 2, 3) Expecting: 6 ok Trying: multiply( 'baka~', 3) Expecting: 'baka~baka~baka~' ok 1 items had no tests: _main_ 1 items passed all tests: 2 tests in _main_.multiply 2 tests in 2 items. In addition: The verbose parameter is used to control whether to output detailed information. It can't be written anywhere like ordinary comments. This is where it can be referenced by the _doc_ attribute. The connotation of this sentence is that the position of the test case must be placed at the beginning of the entire module file or immediately after the object declaration statement. The test case of doctest mentioned earlier is like a docstring. Pay attention to the position of the test code. Unnecessary_math.py: lang:python """ 这里也可以写""" def multiply (a,b): """ > multiply(2,3) 6 > multiply('baka~',3) 'baka~baka~baka~' """ return a*b if _name_ = '_main_': import doctest doctest.testmod(verbose= True) The example used below is a module with only one function, in which two doctest test cases are checked in. After writing a module, they test the function one by one in the shell, and finally copy and paste the shell session into a doctest use case. The process of writing doctest is as if you really imported the module to be tested in an interactive shell (such as idle) and then started to test the functions in the module one by one. "It looks like the docstring in the code." If you think so, you're half right.

The doctest module searches for snippets of Python code that look like interactive sessions, then tries to execute and verify the resultsĮven if we have never encountered doctest before, we can still see a hint from this name. In the official Python documentation, doctest is introduced like this: Go from doctest is a standard module that comes with the Python distribution.
