Let's start by looking at the fixture code for the previous example, shown in part again:

CalculatedDiscount
$		discount
2000.00		100.00

The fixture code is as follows:

---

public class CalculatedDiscount extends fitlibrary.CalculateFixture{
	private Discount application = new Discount();

	public double discountDollar(double amount) {
		return application.getDiscount(amount);
	}
} 

---

The method discountDollar() is called for each of the rows. The given value is supplied as an argument to the method and the result is compared to the expected value.

The header labels are used to determine the method name, being the expected column label followed by each of the given column labels ("discount" + "$"). This name is converted into a valid Java method name based on extended camel[?]. While this can result in some weird method names, it does given the Fit test writer considerable freedom of expression.

In General

• For each expected column in a CalculateFixture table, there is a distinct method. The name of the method is created from the expected column label followed by each of the given column labels. The method has a parameter for each of the given columns and returns a result which is compared against the expected value.
• As with DoFixture[?], a SystemUnderTest object may be associated with a CalculateFixture. If the fixture itself doesn't have a required method, the one in the SystemUnderTest is called instead. This means that the fixture acts as an adapter only when necessary, to map actions in the table into methods in the SystemUnderTest.
• To enable a specific string to signify repeating of the previous given value (" " is used in ColumnFixture), call the CalculateFixture method setRepeatString().
• To enable a specific string to signify an exception is expected ("error" is used in ColumnFixture), call the CalculateFixture method setExceptionString().

In ColumnFixture, " " as an expected value means that the actual value is displayed in the report. There is currently nothing directly equivalent to this in CalculateFixture. The closest is a show special action in DoFixture[?]
