ConstraintFixture is a variation of CalculateFixture that has an implied expected value of true (or false).
For example, the following ConstraintFixture table just has given columns and is checking the constraint that the a value is less than the b value:
The two rows are colored green because the constraint is satisfied. For each value row, the method aB() is called in the class SucceedConstraint, as follows:
If the method returns true the row passes, otherwise it is colored red.
We can also have a fixture that expects the result to be false, such that a is not less than b:
The fixture class is as follow:
Notice how it passes the expected value of false to the superclass.

For example, the following ConstraintFixture table just has given columns and is checking the constraint that the a value is less than the b value:
| fitlibrary.specify.SucceedConstraint | |
| a | b |
| 1 | 2 |
| 2 | 5 |
The two rows are colored green because the constraint is satisfied. For each value row, the method aB() is called in the class SucceedConstraint, as follows:
public class SucceedConstraint extends ConstraintFixture {
public boolean aB(int a, int b) {
return a < b;
}
}
If the method returns true the row passes, otherwise it is colored red.
We can also have a fixture that expects the result to be false, such that a is not less than b:
| fitlibrary.specify.FailConstraint | |
| b | a |
| 1 | 2 |
| 2 | 5 |
The fixture class is as follow:
public class FailConstraint extends ConstraintFixture {
public FailConstraint() {
super(false);
}
public boolean bA(int b, int a) {
return a < b;
}
}
Notice how it passes the expected value of false to the superclass.
