Writing fixtures for Setup tables
As we've seen in Setup Definition, a table of rules is used to simplify the creation of a particular state for the system under development. Once the state is created, we can focus on the business process to test.
This page shows the fixture code that supports the examples introduced in the Writing a Setup specification.

Fixture to create bank customers
Consider the example of setup table described in Writing a Setup specification:
...
The fixture code to support this example in Java is the class AGroupOfCustomersFixture shown below.

bank.openSavingsAccount(number, new Owner(firstName, lastName)).deposit(balance);
else if(AccountType.CHECKING == type)
bank.openCheckingAccount(number, new Owner(firstName, lastName)).deposit(balance);

How is the table processed?
When it runs this table, reads the first row to select the interpreter and fixture. It then reads the second row to know what the attribute columns are. Finally, it starts creating entries from the third row down to the end of the table.
For the third row carries out the following sequence of steps:
It assigns the data 11111-11111 to number, checking to type, Fred to first name, Flintstone to last name and $250.00 to balance.
It then calls the method enterRow() of the fixture AGroupOfCustomersFixture to open a bank account with the given data.
