Vertical Slices Over Horizontal Layers

This generated surface maps a learner-facing curriculum unit to its canonical source routes.

Curriculum surface​

  • Open learner-facing unit
  • Curriculum path: content/curriculum/production/semester-10-capstone/module-02-implementation-testing/concepts/cluster-01-walking-skeleton-first/02-vertical-slices-over-horizontal-layers-primary.md
  • App: production
  • Semester: semester-10-capstone
  • Module: module-02-implementation-testing
  • Unit kind: concept
  • Curation level: module_curated

Learning objectives​

  • Explain Vertical Slices Over Horizontal Layers as the disciplined conversion of design intent into working software with evidence, not just feature completion.
  • Use Vertical Slices Over Horizontal Layers to reason about feedback loops, test confidence, quality boundaries, and the cost of weak implementation discipline in a capstone project.
  • Use clean-code, good-code-bad-code, refactoring, software-engineering-at-google to connect the learner page to code structure, verification strategy, and the practical mechanics of shipping a reliable implementation.

Prerequisites​

  • Comfort with the capstone domain, architecture direction, and the need to prove behavior through repeatable tests and evidence.

Source books​

  • clean-code
  • good-code-bad-code

External enrichment​

  • Martin Fowler: Test Pyramid (read_if_stuck) - Keeps testing strategy tied to confidence and feedback speed instead of accidental test sprawl.
  • Google Testing Blog (optional_deep_dive) - Adds practical testing perspectives from large production systems that are useful when capstone quality starts to drift.
