A Fixture for entering rows of data.

Sometimes, as in the BuildOperateCheck pattern, we want to add a bunch of data to a database. Or sometimes we want to call a function over and over again with different arguments. This is often done in order to configure the system for a subsequent fixture that will run tests based upon the configured data.

We have seen examples where this was done with the help of a valid() function.

Row Entry Fixture is a better option in many cases.

public abstract void enterRow() throws Exception;
Override this function to add your row of data. Throw an exception if there are any problems.

Here is an example of a very simple Row Entry Fixture:
public class RowEntryExample extends RowEntryFixture
  public int v;
  public void enterRow() throws Exception
    if (v == 0)
      throw new Exception("Oh, no!  Zero!");

And here you can see it running.
