Column fixtures have a virtual Execute() method which is called before the first check operation in a given row. We can override this method to handle some processing after input/before check.

public class ExecuteExampleFixture : ColumnFixture {
    public int IntField;
    public override void Execute() { IntField = IntField*2; }
}

when test is⇓ story test fixture check test result execute example int field int field? 1 2 2 4 execute example int field int field? 1 2 2 4

execute example int field int field? 1 2 2 4

then result is

execute example int field int field? 1 2 2 4

Column fixtures can use a Domain Adapter.

when test is⇓ story test fixture check test result use column with new sampledomainadapter name lower case name? Bill bill use column with new sampledomainadapter name lower case name? Bill bill

use column with new sampledomainadapter name lower case name? Bill bill

then result is

use column with new sampledomainadapter name lower case name? Bill bill

To create objects, a column heading uses a "new" prefix. An object is created using the data cell as a constructor parameter. The newly-created object becomes the System Under Test.

when test is⇓ story test fixture check test result column new sample domain name? Bob Bob column new sample domain name? Bob Bob

column new sample domain name? Bob Bob

then result is

column new sample domain name? Bob Bob

A member name beginning with "new" does not create a new object.

when test is⇓ story test fixture check test result use column with new sample domain new name new name? Ted Ted use column with new sample domain new name new name? Ted Ted

use column with new sample domain new name new name? Ted Ted

then result is

use column with new sample domain new name new name? Ted Ted
