I was tinkering with doing the setups with our unit test specifciations which go like
Specification for SUT when behaviour X happens in scenario Y
Given that this thing
And also this other thing
When I do X...
Then It should do ...
And It should also do ...
I wrapped each of the steps of the GivenThat in Actions... any feed back whether separating with Actions is good / bad / or better way to make the GivenThat clear?
/// <summary>
/// Given a product is setup for injection
/// And Product Image Factory Is Stubbed();
/// And Product Size Is Stubbed();
/// And Drawing Scale Is Stubbed();
/// And Product Type Is Stubbed();

protected override void GivenThat()
{
base.GivenThat();
Action givenThatAProductIsSetupforInjection = () =>
{
var randomGenerator =
new RandomGenerator();
this.Position = randomGenerator.Generate<Point>();
this.Product =
new Diffuser
{
Size =
new RectangularProductSize(
2.Inches()),
Position = this.Position,
ProductType =
Dep<IProductType>()
};
};
Action andProductImageFactoryIsStubbed = () => Dep<IProductBitmapImageFactory>().Stub(f => f.GetInstance(Dep<IProductType>())).Return(ExpectedBitmapImage);
Action andProductSizeIsStubbed = () =>
{
Stub<IDisplacementProduct, IProductSize>(p => p.Size);
var productBounds =
new ProductBounds(Width.Feet(), Height.Feet());
Dep<IProductSize>().Stub(s => s.Bounds).Return(productBounds);
};
Action andDrawingScaleIsStubbed = () => Dep<IDrawingScale>().Stub(s => s.PixelsPerFoot).Return(PixelsPerFoot);
