[Python] Working with python unit tests, tring to patch a class but is not working

I have code with below functionality

src/client.py

class Client1(object):
def foo(self, t):
return f"foo-{t}"

def get_foo(self, type):
return self.foo(type)


src/get_foos.py


from .src import Client1

client = Client1()

def get_foo():
foo = client.get_foo("foo")
return foo

def get_bar():
bar = client.get_foo("bar")
return bar



I am trying to create a unit test for get_foo() and get_bar().

I do following

src/test/test_get_foos.py

from src.get_foos import get_foo

@patch(src.get_store.Client1)
def test_get_store(self,mock_client)
mock_client.get_foo.return_value = 'myfoo'
result = get_foo()
assert result === 'myfoo'


But I observe that the patch does not work and the test fails. I checked all the resources online and everywhere I see the same pattern to mock a class class which is outside a function.

I have more than 6 methods in my actual code and I don't want to make a new instance of Client1 everywhere.
