尝试运行xunit和使用套件的鼻子测试输出

我正在尝试使用套件在web2py中运行鼻子测试并使用xunit输出，它会创建xml文件，但是即使控制台显示有错误，但也不会将它们写在xml文件中

I'm trying to run nosetests in web2py using suite and outputing with xunit, it creates the xml files but even if the console shows that there were errors, but, they are not been written in the xml file

.py脚本:

suite = TestLoader().loadTestsFromTestClass(globals()[strArchivo+strDirectorio])
            noseargs = ['fake','--processes=0','v=0','--process-timeout=60',
                        '--with-xunit', '--xunit-file=applications/output.xml','--verbosity=0']

            nose.run(argv = noseargs,suite = suite)

控制台输出:
