我在Docker中启动并运行了我的flask webapp,并尝试实施一些单元测试,并且在执行测试时遇到麻烦。在我的容器启动并运行时,我运行以下命令:
docker-compose run app python3 manage.py test
尝试在test
中执行我的manage.py
函数:
import unittest
from flask.cli import FlaskGroup
from myapp import app, db
cli = FlaskGroup(app)
@cli.command()
def recreate_db():
db.drop_all()
db.create_all()
db.session.commit()
@cli.command()
def test():
""" Runs the tests without code coverage"""
tests = unittest.TestLoader().discover('myapp/tests', pattern='test*.py')
result = unittest.TextTestRunner(verbosity=2).run(tests)
if result.wasSuccessful():
return 0
return 1
if __name__ == '__main__':
cli()
但是由于我的start.sh
中有一个Dockerfile
,所以它只执行我的Gunicorn start.sh
,但没有运行我的测试。我只在控制台中看到以下内容,但没有跟踪我的test()
函数。

exec gunicorn -b 0.0.0.0:5000 wsgi --reload --chdir usb_app --timeout 9999 --workers 3 --access-logfile - --error-logfile - --capture-output --log-level debug
有人知道为什么或如何在现有容器中执行测试功能而不必再次启动Gunicorn工人吗?
答案 0 :(得分:2)
我假设start.sh
是您的入口点。如果不是,您可以将其作为入口点,而不是将其放在CMD
中。
我们可以使用--entrypoint
参数覆盖入口点脚本,如下所示-
docker-compose run --rm --entrypoint "python3 manage.py test" app
