Required tests

[Matt-Esch]

• Initialisation tests
  • The thunk is initialised using the data that was passed
  • The initialised data can be null or undefined
  • The initialised data can be a value type (Number, String, Boolean)
  • The initialised data can be an object
  • The initialised data can be an array
  • The initialised data can be a function
  • Multiple arguments can be passed
• Diff tests
  • Valid different values for identical types cause rerender
  • If the render functions are not identical, the node is rerendered (even if the underlying data is the same)
  • Identical null/undefined/value types result in noop
  • Identical object types result in noop
  • Shallow equal object types result in noop
  • Different permutations of data type cause rerender
    • undefined can replace null/value/object/array/function
    • null can replace undefined/value/object/array/function
    • value can replace undefined/null/object/array/function
    • object can replace undefined/null/value/array/function
    • array can replace undefined/null/value/object/function
    • function can replace undefined/null/value/object/array
  • A different number of arguments causes rerender
  • Consistent with 0 arguments results in noop
  • Objects with different prototypes are different
  • Extra keys on arrays are compared
• Edge/Mutability tests
  • Shallow mutating the object/array used to initialise thunk does not affect the initialise data
  • Cached vnodes can be used by render
