6.3. Features supporting future-proofing and usability
A future-proof test will fail only for the right reasons in the face of big changes to the production code in the future. Usability is the quality that allows you to easily understand and use the framework. Isolation frameworks can be very easy to use badly and cause very fragile and less-future-proof tests.
These are some features that promote test robustness:
- Recursive fakes
- Defaulting to ignored arguments on behaviors and verifications
- Nonstrict verifications and behavior
- Wide-area faking
6.3.1. Recursive fakes
Recursive faking is a special behavior of fake objects in the case where functions return other objects. Those objects will always be fake, automatically. Any objects returned ...
