Advanced TDD (Episode 19.1)

• Laws:
  1. Dont write any PROD code until you have a failing unit test
  2. Stop writing the test as soon as it fails (including compiling errors)
  3. Stop writing PROD code as soon as the test passes
• Cycle:
  1. Red
  2. Green
  3. Refactor
• Write degenerate tests first

SOLID Components (Episode 15)

• Differences beetween libraries and frameworks
  • Application calls subroutines libraries
  • Framework calls application
• Component: independant deployable library
• When designing components is important to identify actors in order to split responsibilities
• When describing behavior modules avoid saying low level words, instead use abstractions
• Good episode in how to design modules

Component Cohesion (Episode 16)

rgkobashi

Foundations of the SOLID principles (Episode 8)

• Design smells:
  • Immobility
  • Viscosity: how easy is to add design-preserving code to a system
  • Needles complexity
• Dependency management principles:
  • SOLID
  • Component cohesion principles
  • Component coupling principles

Code smells (Episode 1)

• Rigidity: difficult to make changes (small change causes a cascade of subsequent changes)
• Fragility: a single change causes breaks in many places
• Inseparability: no reusability
• Opacity: code is hard to understand

Naming (Episode 2)

• Make sure you communicate intent
• Avoid disinformation
• Use pronounceable names

// The methods of Appearance.StatusBar can be used to hide and show the status bar on iOS.
// As mention in other places, this is more like hack than a solution. I personally don't like it.
// However if on your application you are making use of navigationBar or similar components,
// hidding the statusBar on the right way (overriding `prefersStatusBarHidden`) will mess with your constraints.
// For more details please refer to this answer and its comments: https://stackoverflow.com/a/44066303/8483739

struct Appearance {
    private init() {}
