请教： Python coverage 和 unittest 结合报错，狗书单元测试这一块

[wuwuwu5]

最近在看 flask web 开发一书，看到获取代码测试报告那里，对照的书，使用脚本启动 coverage。运行的时候报错 AssertionError: Expected current collector to be <Collector at 0x10366b0d0: CTracer>, but it's <Collector at 0x103cac4d0: CTracer>

这是我的代码 app = creat_app('development') app.app_context().push() app.config['debug'] = True manager = Manager(app)

COV = None if os.environ.get('FLASK_COVERAGE'): import coverage COV = coverage.coverage(branch=True, include='app/*') COV.start()

@manager.command def test(cover=False): """run the unittest""" if cover and not os.environ.get('FLASK_COVERAGE'): import sys os.environ['FLASK_COVERAGE'] = '1' os.execvp(sys.executable, [sys.executable] + sys.argv) import unittest tests = unittest.TestLoader().discover('test') unittest.TextTestRunner(verbosity=2).run(tests) if COV: COV.stop() COV.save() print 'Coverage Summary:' COV.report() basedir = os.path.abspath(os.path.dirname(file)) covdir = os.path.join(basedir, 'tmp/coverage') COV.html_report(directory=covdir) print 'html version: file://%s/index.html' % covdir COV.erase()

if name == 'main': print app.url_map db.drop_all() db.create_all() manager.run()

COV.stop() 这一句报错 我终端运行的是 python manager.py test --cover
