• Unit testing with Polly - with examples
• [1] I want to unit-test what my code does, independent of Polly policies I apply
• Use DI to separate policy creation from policy usage
• Using a mock to verify that the system-under-test uses the policy
• Use PolicyRegistry with DI, to work with policy collections
• Stubbing Polly out of tests with PolicyRegistry
• Using mock policies in tests, with PolicyRegistry
• Use a policy factory, if you generate policies dynamically
• [2] I want to test that I've configured Polly policies to achieve my desired resilience strategy
• [2a] Test policies with integration tests through the consuming code
• [2b] Test policies with unit-tests, independent of consuming code
• Recommendation: Focus on testing your own logic rather than Polly
• [3] I want to unit-test how my code reacts to results or faults returned by the execution through Polly
• [4] I want to unit-test that the Polly policies I apply actually do what they say on the tin
