Stampede at the Gates
AI generation exposed an already flawed SDLC: faster code review moves the queue to verification, which needs functional acceptance testing at the boundary.
Topic
Testing
Which layer proves what, how tests are arranged, and what a passing test is actually evidence of.

AI-native SDLC
Engineering both gates requires certified code review, functional acceptance tests at the boundary ratified by humans, and verification against the specification.

Validating Formal Arguments? No Thank You!
Validate and clean data at the front and back doors; skip checks on internal formal arguments. Immutable DTOs preserve trust, one exception reports all errors, and black box tests exercise the doors.

Builder Pattern and C# Expressions
Test-data builders keep each scenario's chosen values visible. C# expression trees select model properties, and stored overrides preserve explicit nulls.

Custom Data Structure: A One-to-Many Mapping
A one-to-many map must enforce unique values and return a key from a value. Shared tests and four implementations show how correctness shapes a benchmark.
Writing
Mocking? No Thank You!
Test whole features through the public surface so regression tests survive later design changes. Class mocks bind tests to internals; transport doubles cover rare external failures.

The Configuration Provider: Roles and Responsibilities
A Configuration Provider hides the source and returns validated, typed settings. Useful exceptions and composed settings providers keep configuration rules in one place.

Using LocalDB in Visual Studio Online
Run database tests on Visual Studio Online by creating a LocalDB instance, publishing a dacpac, and invoking the batch file from the build definition's Pre Test Script.
