Targeted to .Net Core 3.1

Installation

Install the ModelFactory NuGet Package.

Package Manager Console

Install-Package ByteDecoder.ModelFactory

.NET Core CLI

dotnet add package ByteDecoder.ModelFactory

Examples and usage

An easy way to define data for models is to create in your test project, internal static classes that define custom data for your models, and then create instances of these model data templates for testing, minimizing code duplication, and maximizing extensibility and maintainability via the ModelFactory. It also takes the advantage of method group provided by C#.

You can create a single instance or a collection of a given type T

// Model Example

public class Command
{
  public int Id { get; set; }
  public string HowTo { get; set; }
  public string Platform { get; set; }
  public string CommandLine { get; set; }
}

// Data Template example method
internal static class CommandFactory
{
  internal static void BasicBuildOne(Command cmd)
  {
    cmd.HowTo = "Do Something";
    cmd.Platform = "Some Platform";
    cmd.CommandLine = "Some Command";
  }
}

// Now, creating model instances with ModelFactory

[Fact]
public void Create_ShouldCreateModel_WhenMethodIsProvided()
{
  // Arrange
  // Act
  var model = ModelFactory<Command>.Create(CommandFactory.BasicBuildOne);

  // Assert
  Assert.NotNull(model);
  Assert.Equal("Do Something", model.HowTo);
}

[Fact]
public void Create_ShouldCreateCollection_WhenMethodIsProvided()
{
  // Arrange
  // Act
  var models = ModelFactory<Command>.Create(CommandFactory.BasicBuildOne, 2);

  // Assert
  Assert.NotNull(models);
  Assert.Equal(2, models.Count());
}

// Also, you can define inline the model data as well
var model = ModelFactory<Command>.Create(m =>
  {
    m.Id = 666;
    m.HowTo = "UPDATED";
    m.Platform = "UPDATED";
    m.CommandLine = "UPDATED";
  });
