Nosetest覆盖范围未显示以Test开头的类

Question

Im generating a coverage report with nosetest using the following command:

nosetests --exe --with-coverage --cover-html --cover-package=Mypackage Tests/

In my tests Im using some classes and almost all classes are found except one thats called:

TestCasesFilter

After trying some thigns I found out that when I rename the class to something else eg OneTestCasesFilter the class is added to the coverage report. Our naming convention requires us to name the class after the table in the datbase that is written to so in this case TestCases. Is it possible to add the class to the coverage report without renaming the class?

Im using:

python 2.7.14
coverage 4.4.1
nose 1.3.7

Background

My setup is a bit different than yours, but I was seeing a similar problem. I have a setup.cfg file in the root of my python package that looks like this:

[nosetests] with-coverage=1 cover-xml=1 cover-xml-file=coverage.xml cover-package=companyname

With this setup.cfg file, I was not seeing companyname/test_base.py show up in the coverage report that nosetests spits out at the end. I was, however, seeing it show up when I ran coverage report so I know the data is being collected.

My Fix

Looking at the documentation I saw a couple of potential options to fix. I was able to resolve the issue by adding cover-tests=1 to my setup.cfg file. The docs describe this option as

--cover-tests Include test modules in coverage report

It looks like whatever algorithm nose uses to determine what is a "test" isn't very smart and maybe only looks at class names

Your Fix

Since you're using the command-line to pass options, I think you need to add --cover-tests when you invoke nosetests
