What is custom assertion?
Simply put, custom assertions allow creating assertions specific to our own classes, allowing our tests to better reflect the domain model.
What is assertion message?
From a test readability perspective, assertion messages are code comments. Instead of relying on them, refactor tests to be self-documenting. In terms of ease of diagnostics, a better alternative to assertion messages is: Making tests verify a single unit of behavior.
Should I use python assert?
Assert statements are used to debug code and handle errors. You should not use an assert statement in a production environment. When debugging programs in Python, there may be times when you want to test for a certain condition. If that condition is not met, the program should return an error.

Which is an example of a custom assertion message?
For example, a failure in the following assertion: The combination of such framework-generated messages and human-readable test names makes 90% of custom assertion messages worthless even from the ease of diagnostics standpoint. The only exception is long-running end-to-end tests.
Do you need to test a custom assertion?
Testing zealots would also write a Custom Assertion Tests (a Self-Checking Test (see Goals of Test Automation on page X) for Custom Assertions) to verify the Custom Assertion. The benefits of doing so are obvious: increased confidence in our tests.
What’s the difference between SUT and custom assertion?
The Custom Assertions follow the normal Simple Success Test (see Test Method on page X) and Expected Exception Test (see Test Method) templates with one minor difference: Because the Assertion Method is the SUT, the exercise SUT and verify outcome phases of the Four-Phase Test (page X) are combined into a single phase.
