nosetests

I'm trying to set up some automatic unit testing for a project. I have some functions which, as a side effect occasionally call another function. I want to write a unit test which tests that the second function gets called but I'm stumped. Below is pseudocode example: def a(self): data = self.get() if len(data) > 3500: self.b() # Bunch of other magic, which is easy to test. def b(self): serial.write("\x00\x01\x02") How do I test that b() -gets called? alecxe You can mock the function b using mock module and check if it was called. Here's an example: import unittest from mock import patch def a

I am able to setup nose tests to run with the @attr tag. I am now interested in know if I can append to the end of the test name, the @attr tag? What we are trying to do is add a tag if our tests run into an issue and we write up a defect for it, we would then put the defect number as an @attr tag. Then when we run we could easily identify which tests have open defects against them. Just wondering if this is even possible, and where to go to see how to set it up? EDIT RESULTS RUNNING WITH ANSWER: Test Results: So I sort of know what is going on, if I have the @fancyattr() at the class level it

I'm on exercise 46 of Learn Python the Hard Way , and I'm meant to install nose and run nosetests. I've installed nose already using pip, but when I run nosetests in the directory above the 'tests' folder, I get the error: 'nosetests' is not recognized as an internal or external command, operable program or batch file. If it's relevant, I've already modified the PATH variable to include full path of Python27/Scripts and Python/Lib/site-package . If you are still having trouble after following Warren Weckesser's instructions try uninstalling and reinstalling. Using pip: pip uninstall nose I

I have a Pylons 1.0 app with a bunch of tests in the test/functional directory. I'm getting weird test results and I want to just run a single test. The nose documentation says I should be able to pass in a test name at the command line but I get ImportErrors no matter what I do For example: nosetests -x -s sometestname Gives: Traceback (most recent call last): File "/home/ben/.virtualenvs/tsq/lib/python2.6/site-packages/nose-0.11.4-py2.6.egg/nose/loader.py", line 371, in loadTestsFromName module = resolve_name(addr.module) File "/home/ben/.virtualenvs/tsq/lib/python2.6/site-packages/nose-0.11

Can a variable be moved from the cmd to my module when using nose tests? Scenario: I am running tests with selenium that need to run against both production and sandbox versions of the website (www.sandbox.myurl.com and www.myurl.com) I wrote a custom nose plugin that lets me set which environment to run against EDITED CODE env = None class EnvironmentSelector(Plugin): """Selects if test will be run against production or sandbox environments. """ def __init__(self): Plugin.__init__(self) self.environment = "spam" ## runs against sandbox by default def options(self, parser, env): """Register

I'm writing a test suit with nose, and would like failing cases to display an output like "FAILED: is_even(5): Not even" instead of the default output: ====================================================================== FAIL: seed_db.test_generator(5,) ---------------------------------------------------------------------- Traceback (most recent call last): File "/usr/local/lib/python2.7/dist-packages/nose/case.py", line 197, in runTest self.test(*self.arg) File "/home/apurcell/tests/prism/seed_db.py", line 59, in is_even nose.tools.eq_(x % 2, 0, msg="Not even") File "/usr/local/lib/python2

We are trying to implement an automated testing framework using nose. The intent is to add a few command line options to pass into the tests, for example a hostname. We run these tests against a web app as integration tests. So, we've created a simple plugin that adds a option to the parser: import os from nose.plugins import Plugin class test_args(Plugin): """ Attempting to add command line parameters. """ name = 'test_args' enabled = True def options(self, parser, env=os.environ): super(test_args, self).options(parser, env) parser.add_option("--hostname", action="store", type="str", help=
