ddt: add up change
# description 1c 5c 10c 25c 50c $1 total cents? $ total?
some simple addition 2 2 4 0 0 0 52 0.52
save the total cents in a symbol 56 0 0 0 1 20 $totalCents= 21.06
now use the total cents that were stored $totalCents 0 0 0 0 10 3106 ~=31.1 An example for Value Comparisons

This is a dynamic decision table. The syntax is the same as that of a Decision Table, except that the first cell has to be prefixed by ddt: or dynamic decision:.

The dynamic decision table provides an alternative to the Decision Table when the Graceful Names of the column headers are not well suited as method names.

The source code of the fixture AddUpChange looks like this:
public class AddUpChange {
  private Integer totalCents = 0;
  private static Map<String, Integer> COIN_VALUES = new HashMap<String, Integer>();
  static {
    COIN_VALUES.put("1c", 1);
    COIN_VALUES.put("5c", 5);
    COIN_VALUES.put("10c", 10);
    COIN_VALUES.put("25c", 25);
    COIN_VALUES.put("50c", 50);
    COIN_VALUES.put("$1", 100);
  }

  public void reset() {
    totalCents = 0;
  }

  public void set(String coin, Integer amount) {
    if (!COIN_VALUES.containsKey(coin)) {
      throw new IllegalArgumentException("Unknown coin type " + coin);
    }
    totalCents += amount * COIN_VALUES.get(coin);
  }

  public String get(String requestedValue) {
    if ("$ total".equals(requestedValue)) {
      return String.format(Locale.US, "%.2f", totalCents / 100.0);
    }
    return String.format("%d", totalCents);
  }
}


The cells with column headers that do not end with a ? are considered inputs and they result in a method call set(header, value). The cells with column headers that end with a ? are considered outputs and they result in a method call get(header).

Apart from that the same methods are called as for a Decision Table (table, beginTable, reset, execute, endTable).

As in a Decision Table, all the set method calls are done before the execute call and all the get method calls are done after the execute call.

You can use Symbols In Tables and Value Comparisons as well as comment column headers prefixed with # and use additional cells as comments.
