NBuilder

• Bug Guid.Empty being incremented. Solution was to disable NBuilder's property name for static or read-only fields. Thanks to Dominic Hemken for the PR.
• Bug CreateListOfSize had undefined behavior when called from the static Builder and executed on multiple threads at the same time. While the future of NBulider will be to remove the static builder, it's a defect in the current implementation. Thanks to Ovidiu Rădoi for the PR.

• Breaking Change: WithConstructor
  • No longer takes an Expression<Func<T>>.
  • Takes a Func<T>.
  • Marked [Obsolete] in favor of WithFactory
  • This change was to address an issue in which the constructor expression was not being reevaluated for each item in a list.
• Feature: @AdemCatamak Added support for IndexOf as part of the ListBuilder implementation.

var products = new Builder()
    .CreateListOfSize<Product>(10)
    .IndexOf(0, 2, 5)
    .With(x => x.Title = "A special title")
    .Build();

• Feature: @PureKrome Added support for DateTimeKind to RandomGenerator

var result = randomGenerator.Next(DateTime.MinValue, DateTime.MaxValue, DateTimeKind.Utc);

• Feature: Added DisablePropertyNamingFor(PropertyInfo) overload to BuilderSettings.
• Feature: Added TheRest as an extension to the ListBuilder.

var results = new Builder()
        .CreateListOfSize<SimpleClass>(10)
        .TheFirst(2)
        .Do(row => row.String1 = "One")
        .TheRest()
        .Do(row => row.String1 = "Ten")
        .Build()
    ;

• Bug: Last item in enum is never generated when generating property values randomly.
• Bug: Lost strong name when porting to .NET Standard.
• Bug: Non-deterministic behavior when calling TheLast multiple times for the same range.

• Added support for disabling property naming via an interface:

In a multi tenant scenario, the db entities usually have a property that denotes that they are for that specific tenant:

public interface ITenantEntity
{
    int TenantId {get; set;}
}

public class User: ITenantEntity
{
    public int TenantId {get; set;}
    ...
}

public class Car: ITenantEntity
{
    public int TenantId {get; set;}
    ...
}

When writing tests for the db layer, it is useful to disable the autoassignment for this property by just specifying an interface in BuilderSetup.DisablePropertyNamingFor.

• Dropped support for .NET 3.5
• Added support for .NET Standard 1.6

This is a catch-up release of cumulative changes to NBuilder that have accrued since the last offical release in 2011. As it's been 5 years since the last official release, it's hard to know everthing that's changed.

Breaking changes

Obsolete methods have been removed.

Any method previously marked with the Obsolete attribute has now been removed.

Silverlight No Longer Supported

As Silverlight is effective a dead technology, we have officially ended support for it. This will allow us to better focus on a forthcoming release with .NET Core support.

New Features

Builder has a non-static implementation.

This will allow you to create customized BuilderSettings for different testing scenarios.

Old Code

    var results = Builder<MyObject>.CreateListOfSize(10).Build();

New Code

    var settings = new BuilderSettings()
    var results = new Builder(settings).CreateListOfSize<MyObject>(10).Build();

With and Do action now supports a signature that receives an index

Example

    var builderSettings = new BuilderSettings();
    var list = new Builder(builderSettings)
            .CreateListOfSize<MyClassWithConstructor>(10)
            .All()
            .Do((row, index) => row.Int = index*2)
            .WithConstructor(() => new MyClassWithConstructor(1, 2f))
            .Build();

Bug Fixes

• The decimal separator was wrong for some cultures.
• Random number generation of decimals was sometimes incorrect.
• Sequences were not created in the correct order.
• Random strings were not always generated between the expected lengths.
