我使用 python 模拟来断言特定对象是使用正确的参数创建的。这就是我的代码的样子:
class Installer:
def __init__(foo, bar, version):
# Init stuff
pass
def __enter__(self):
return self
def __exit__(self, type, value, tb):
# cleanup
pass
def install(self):
# Install stuff
pass
class Deployer:
def deploy(self):
with Installer('foo', 'bar', 1) as installer:
installer.install()
现在,我想断言installer
是用正确的参数创建的。这是我到目前为止的代码:
class DeployerTest(unittest.TestCase):
@patch('Installer', autospec=True)
def testInstaller(self, mock_installer):
deployer = Deployer()
deployer.deploy()
# Can't do this :-(
mock_installer.__init__.assert_called_once_with('foo', 'bar', 1)
这是我得到的错误:
File "test_deployment.py", line .., in testInstaller
mock_installer.__init__.assert_called_once_with('foo', 'bar', 1)
AttributeError: 'function' object has no attribute 'assert_called_once_with'
这是固定代码(称之为test.py
)。谢谢大家!
