    • A. Framework
    • B. Test Runner
    • C. Brains
  • II. Test Architecture
    • A. Test Fixture
    • B. Setup
    • C. Test Method
    • D. TearDown
  • III. Process
    • A. Red
    • B. Green.
    • C. Refactor.
    • D. Rinse and Repeat.
  • IV. Conventions
    • A. At least one testfixture per class.
    • B. At least one test method per public method.
    • C. Test Method naming conventions
      • i. MethodUnderTest_ConditionUnderTest_ExpectedResult
    • D. Test Method section conventions
      • i. Arrange
      • ii. Act
      • iii. Assert
  • V. Other Issues
    • A. Productivity Study
    • B. Testing the UI
      • i. Not technically possible without more tooling/infrastructure
      • ii. MVC patterns increate unit-test coverage.
      • iii. Legacy code.
        • a. Presents special problems.
        • b. Touching untested legacy code is dangerous.
        • c. Boy-Scout rule.
        • d. Use your own judgment
    • C. Pros and Cons
      • i. Pros
        • a. Quality.
        • b. Encourage a more loosely-coupled design.
        • c. Document the work that is done.
        • d. Regression testing.
        • e. Increased confidence in working code means changes are easier to make.
        • f. Encourages devs to think about code in terms of API instead of implementation.
          • 1. Makes code more readable.
          • 2. Readable code communicates intent more clearly.
          • 3. Readable code reduces the need for additional non-code documentation.
      • ii. Cons
        • a. Takes longer to develop.
        • b. Test code must be maintained as well.
        • c. Requires that devs adapt to new ways of thinking about code.
    • D. Notes
