6 micro-topics in Reliability & Operations, each with the evidence that proves you have it and the written reason behind every link. Before you start, it rests on 5 other domains. Downstream, it holds up 2 domains.
6 topics · depth 5–8 of 16 · 5 internal links · 5 in · 2 out
Load-bearing links first. Each one says what in this domain rests on what outside it, and why.
1 link
Test user interactions rests on Handle events
Simulated events mirror real ones.
1 link
Unit test JavaScript rests on Write and call functions
You unit test functions.
1 link
Write end-to-end tests rests on Route with the file system
End-to-end tests drive real routes.
1 link
Test components as a user would rests on Compose components
You test components.

Unit test JavaScript rests on Reason about the testing pyramid
Unit tests are the base of the pyramid.
In prerequisite order. Each idea names the artifact that closes it, the market demand that put it on the map, and what it stands on.
Depth 5 · procedural · unassisted · M11 §11.2
Structures tests with describe, it and matchers
Reason about the testing pyramid · Testing Foundations
Unit tests are the base of the pyramid.
Write and call functions · JavaScript Core
You unit test functions.
Depth 6 · procedural · unassisted · M11 §11.2
Isolates the unit under test
Mocking isolates a unit under test.
Depth 6 · procedural · unassisted · M11 §11.3
Queries by role and text, not implementation
Compose components · React
You test components.
Component tests use the same runner and matchers.
Depth 7 · procedural · unassisted · M11 §11.3
Simulates clicks, typing and selection
Test components as a user would
Interaction tests act on rendered components.
Handle events · The DOM
Simulated events mirror real ones.
Depth 7 · procedural · scaffolded · M11 §11.5
Drives a real browser through a real flow
Route with the file system · Next.js
End-to-end tests drive real routes.
End-to-end is the same idea against a real browser.
Depth 8 · meta · scaffolded · M11 §11.5
Locates elements without brittle coupling
Selector durability is a lesson learned from brittle E2E tests.
Everything downstream that names an idea here as a prerequisite, grouped by where it lives.

Gate merges on checks rests on Unit test JavaScript
A gate needs something worth blocking on.

Mock external APIs rests on Mock dependencies
Mocking transfers across languages.
