Class ParameterSupplier
java.lang.Object
org.junit.experimental.theories.ParameterSupplier
- Direct Known Subclasses:
- TestedOnSupplier
public abstract class ParameterSupplier
- extends Object
Abstract parent class for suppliers of input data points for theories. Extend this class to customize how Theories
runner
finds accepted data points. Then use your class together with @ParametersSuppliedBy on input
parameters for theories.
For example, here is a supplier for values between two integers, and an annotation that references it:
@Retention(RetentionPolicy.RUNTIME)
@ParametersSuppliedBy(BetweenSupplier.class)
public @interface Between {
int first();
int last();
}
public static class BetweenSupplier extends ParameterSupplier {
@Override
public List<PotentialAssignment> getValueSources(ParameterSignature sig) {
List<PotentialAssignment> list = new ArrayList<PotentialAssignment>();
Between annotation = (Between) sig.getSupplierAnnotation();
for (int i = annotation.first(); i <= annotation.last(); i++)
list.add(PotentialAssignment.forValue("ints", i));
return list;
}
}
