Python's handy test library-nose

Python In addition to UnitTest, there is a faster nose,nose can be said to be a simplification of unittest

But he doesn't need unittest. That must have an intrinsic format, he only needs files, class names, method names, etc. containing test can be

UnitTest is required to manually write the Discover function to traverse the use case

• Name my test modules/files starting with ' Test_ '.

• Name my test functions starting with ' test_ '.

• Name my test classes starting with ' test '.

• Name my test methods starting with ' Test_ '.

• Make sure all packages with test code has an ' init.py ' file.

The introduction of the inside is very detailed, summed up a few common points:

Installation:

Easy_install nose

Run:

nosetests [File]

nosetests [Catalogue]

If you do not add a directory, the default execution of all nose-compliant use cases under the current directory

If you add a directory, run the use case in the specified directory that meets the nose criteria

-V to run the specific process output: nosetests-v

-S prints the print output from the test case to the console, which is very handy when debugging

Nose execution rules: As with UnitTest, the setup is prioritized, the last execution Tesrdown, and the location of the function doesn't matter.

The tools used in nose have many functions, such as unittest-like assertequal

How to use

From nose import tools

And then look inside there's so many ways
