Overview
FakeUp is small project that allows to generate fake data objects with complex structure for tests. The goal is to create API that is concise and modular, so creating fixtures for nested and/or dependent structures is painless or at least a lot less painful. It is just worse version of AutoFixture but some tasks that I was needed can be done more easily with FakeUp since it have to narrower scope and more specialized features.
Features highlight
Filling values based on relative paths
For use when you have reoccurring structures with some special cases.
class Foo {
Bar Bar { get; }
Baz Baz { get; }
string Value { get; }
}
class Bar {
Baz Baz { get; }
}
class Baz {
string Value { get; }
}
When creating fixture with following code
var result = FakeUp.NewObject<Foo>(o => o
.FillAll<string>().With("default")
.Fill((Bar bar) => bar.Baz.Value).With("bar baz")
)
You will receive the following:
Foo
Bar.Baz.Value: "bar baz"
Baz.Value: "default"
Value: "default"
Sharing state
When you have values that are dependent on one another, you can use State
to manage shared values.
For example we have following structure:
class ReceiptBook {
public List<Ingredient> Ingredients { get; set; }
public List<FoodReceipt> Receipts { get; set; }
}
class FoodReceipt {
public string Name { get; set; }
public List<Ingredient> Ingredients { get; set; }
}
class Ingredient {
public string Name { get; set; }
}
We want ReceiptBook.Ingredients
to contain all ingredients used in all FoodReceipts
. We can achieve this using object that will track all added ingredients:
class FoodReceiptState
{
public List<Ingredient> AllIngredients { get; } = new List<Ingredient>();
public Ingredient GetIngredient()
{
if (!this.AllIngredients.Any() || new Random().NextDouble() > 0.5)
{
var ingredient = NewIngredient();
this.AllIngredients.Add(ingredient);
return ingredient;
}
return this.AllIngredients[this.Random.Next(0, this.AllIngredients.Count)];
}
private Ingredient NewIngredient() => FakeUp.NewObject<Ingredient>(o => o.FillAll<string>().WithGuid());
}
The idea is, that every time FakeUp
will require FoodReceipt.Ingredient
we will return either new Ingredient
and add it to list or return excising one. So AllIngredients
will always contain all generated ingredients.
Now following declaration will create object with required structure:
FakeUp.NewObject<ReceiptBook>(o => o
.WithCollectionsSize(3)
.AddState(() => new FoodReceiptState())
.FillAll<string>().WithGuid()
.FillAll<Ingredient>()
.With(ctx => ctx.GetState<FoodReceiptState>().GetIngredient())
.Fill(book => book.Ingredients)
.With(ctx => ctx.GetState<FoodReceiptState>().AllIngredients)
);
