Activatory #

Build Status Coverage Status Pub

This project is aimed to bring a test data generator to Dart's ecosystem. This will greatly simplify unit testing and especially Test-Driven Development.

This project is inspired by .NET Autofixture library.

Supported features #

  • Effortless primitive types (String, int, double, bool, DateTime, enums) generating.
  • Effortless complex object generating using constructors/factory methods/named constructors (default values usage is customizable).
  • Overriding default generating behavior with custom factories, pinned values defined by user or auto generated.
  • Overriding default generating behavior for specific cases using any object as a key.
  • Lists (and Iterables) generating with customizable size: it is effortless for primitive types and require explicit registration for enums and complex types.
  • Maps of customizable size generating with explicit registration.
  • Support of recursive graphs (trees, linked lists and etc) with customizable recursion level.
  • Generic class instances generating with explicit factory registration.
  • Customization of ctor resolution: first defined, random, random named, random default.
  • Overriding generated parameters values by type and name for cases when random values are not applicable.
  • Creating aliases for inheritor classes

Roadmap #

This is my first Dart project and, actually, this is "pet-project". So there are no exact plans and etc. For planned features and more see enhancements on github.

v0.0.1-0.0.4 #

  • Added support for primitive objects activation: int, double, String, bool, DateTime
  • Added support for complex object activation by calling ctors, named ctors, factories and using positional arguments

v0.0.5 #

  • Named arguments supported
  • Complex object activation now respects default non null values

v0.0.6 #

  • Added ability to register factory explicitly

v0.0.7 #

  • Added ability to register generated singleton
  • Added ability to register pre defined value

v0.0.8 #

  • Back-ends now can be registered and lookuped using any object as a key
  • useSingleton renamed to pin, useValue renamed to pinValue

v0.0.9 #

  • Added effortless support for primitive types arrays generating (except of enums arrays)
  • Added support for complex types array generating with explicit array registration

Maintenance suggestions

Package is pre-v0.1 release. (-10 points)

While nothing is inherently wrong with versions of 0.0.*, it might mean that the author is still experimenting with the general direction of the API.
