在鼻子测试中关闭覆盖范围

Question

How do I conditionally turn off coverage when running nosetests?

there is a --with-coverage flag that doesn't seem to do all that much. It certainly does not turn off coverage.

Mind you, I like coverage and I want to keep it. I just find it extremely distracting to see its output every single time I run nosetests manually. At that time, I want to see the test results and if anything failed.

My ~/.noserc has the following contents, but renaming the file did not help.

[nosetests]
verbosity=3
with-coverage=0
match=(?:^|[\b_\./-])[Tt]est|^ut_
cover-html=1

Most of the time, I would prefer to have the same nosetests behavior as if there was no coverage installed at all.

Last time I installed nose, I hacked together a --cover-none 1 option by modifying the optparse in the main launch script. Basically, if the flag was set I would flip on the same "coverage is not installed" flag that the program uses to guard against coverage not being installed. Worked fine, a bit kludgy though.

Just remove with-coverage option entirely from config file.

Long story: --with-coverage , like all other plugin turn-on flags is defined as store-true action ( in optparse context ), so any value, even 0, False or None will turn the plugin on. You have to remove the option entirely. When you remove with-coverage, default value of False will be used to turn the coverage plugin off.

Also, try running with nosetests -v 3 to see what else could be messing with your setup. Could you have nose.cfg sitting somewhere in your home directory?
