Microtesting
summary
Claim: fewer, higher-value tests give equal or better confidence and much faster feedback by replacing the rigid pyramid with pragmatic, feature-focused suites. Techniques shown include subcutaneous tests (MVC-level tests hitting real DB and services), using a DI container to resolve test subjects, hand-rolled mocks, object mother and test-data builders, and tools like TestStack.BDDfy, Shouldly and ApprovalTests.net. Examples: student controller, checkout → provisioning JSON (approved diff), and user registration scenarios; the approach reduces brittle unit/UI tests and works in practice to speed releases.
