## Example

```
|eg.Division |
|numerator|denominator|quotient?|
|10 |2 |5.0 |
|12.6 |3 |4.2 |
|22 |7 |~=3.14 |
|9 |3 |<5 |
|11 |2 |4<_<6 |
|100 |4 |33 |
```

where

- eg.division is the fixture code where eg specifies a Java package (or other language namespace), and Division specifies the actual class to be called.
- the rows are processed from left to right,
- the input values are headers without a question mark ?
- the input values are passed to the corresponding fields using setter functions
- the expected value are the header with a question mark (ie quotient?) and can be expressed with operators:
- ~=3.14 - approximately equal
- <5 - less than
- 4<_<6 - between

This decision table would test this Java class:

```
public class Division {
private double numerator, denominator;
public void setNumerator(double numerator) {
this.numerator = numerator;
}
public void setDenominator(double denominator) {
this.denominator = denominator;
}
public double quotient() {
return numerator/denominator;
}
}
```
