To do this, you just need to modify the user-agent, which is a variable within your header that you send in. Headers are bits of data that you share with servers to let them know a bit about you. This is where Python, by default, tells the website that you are visiting with Python's urllib and your Python version. If you want to write a test that sets one or more environment variables, overriding existing values, you can use mock.patch.dict like this: import os from unittest import TestCase , mock from example.settings import Colour , get_settings class SettingsTests ( TestCase ): @ mock . patch . dict ( os . environ , { "FROBNICATION_COLOUR" : "ROUGE" }) def test_frobnication_colour ( self ): colour = get_settings (). frobnication_colour self . assertEqual ( colour , Colour .

Behind the scenes, the interpreter will attempt to find an A variable in the my_package2 namespace, find it there and use that to get to the class in memory. So the code inside my_package2.py is effectively using the my_package2.A variable. Now we're ready to mock objects.

Full console session: The @mock.patch("os.stat") decorator is mocking os.stat(), the constructor method of the stat class. os_stat.return_value by default, returns a new Mock object instance that will be substituted for the constructor method's return value (the stat object instance) - in the scope of def test, which includes the nested function call to original_func. A common use case is to mock out classes instantiated by your code under test. When you patch a class, then that class is replaced with a mock. Instances are created by calling the class. This means you access the "mock instance" by looking at the return value of the mocked class.

If you look closely at your code you'll see that the second property in your test is still an instance of Second, not a mock (you don't pass the mock to first in your code).. The simplest way would be to create a setter for second in First class and pass it the mock explicitly.. Like this: public class First { Second second ; public First(){ second = new Second(); } public String doSecond ...Considering an industry-relevant curriculum with a practical focus, this best in class Data Science with Python training in Bangalore and Delhi NCR gives you the flexibility of attending a data science course through online and self-paced video-based mode as well.

Python Mock/MagicMock enables us to reproduce expensive objects in our tests by using built-in methods (__call__, __import__) and variables to "memorize" the status of attributes, and function calls. We can use them to mimic the resources by controlling how they were created, what their return value is.
