Arbitrary

Library used for generating arbitrary values for unit testing. Allow extension for your own type

Quick start:

To generate a value

var value = Arbitraty.GetNew<int>()    

To generate a range of values:

// generate a range of 12 random int
var value = Arbitraty.GetNewRange<int>(12)    

Static method generation use an internal, immutable default generator

ArbitraryGeneratorBag:

A default generator bag including every following types is available for usage and modification using ArbitratyPredefined static class

// retrieve a default generator:
var generator = ArbitratyPredefined.GetDefault();

---

Default generator included types

• Int
• Uint
• Float
• Long
• Double
• String
• Char
• Byte
• Bool
• DateTime
• TimeSpan
• Guid

---

You could also retrieve an empty one and populate it:

// retrieve an empty generator:
var emptyGenerator = ArbitratyPredefined.GetEmpty();

Add a specific generator

To add a generator, use the RegisterGenerator method:

// retrieve an empty generator:
var emptyGenerator = ArbitratyPredefined.GetEmpty();
    
// register a default int generator
emptyGenerator.RegisterGenerator(ArbitraryGeneratorPredefined.IntGenerator);

it could be chained in a fluent manner:

var generator = ArbitratyPredefined
                  .GetEmpty()                      
                  .RegisterGenerator(ArbitraryGeneratorPredefined.IntGenerator)
                  ...
                  .RegisterGenerator(ArbitraryGeneratorPredefined.DoubleGenerator);

When registering a generator, if a matching type is found, it is overriden

Types generators

Types generators inherit from ArbitraryGeneratorBase and define a GetNew.

you could create whatever generator suit your needs
