Automocking Specification With No Contract

Writing a base specification is very simple, please make sure you read the Introduction.

Let's imagine we have a Calculator class that we want to test

public class Calculator
{
}

Let's declare the base class for all the scenarios:

public class CalculatorSpecification 
    : AutomockingSpecificationWithNoContract<Calculator> 
{
}

By using this base class we get all the benefits from AutoMockingSpecification, the only difference is that the concrete class and the contract are the same.

So, we are ready to write our first scenario:

public class When_calculator_adds_two_numbers : CalculatorSpecification
{
}

So let's review our scenario using Given, When, Then style:

• Given (nothing)
• When I add 2 + 3
• Then I should obtain 5

So let's put in code (remember we don't need Given because there is no condition to check):

protected void WhenIRun() 
{
   this._actual = this.Sut.Add(2, 3);
}

[It]
public void Should_return_the_addition()
{
    this._actual.Should().Be.EqualTo(5);
}
