Introduction
QuickCheckNG is a Java Annotation Processor to generate TestNG @DataProvider methods for a set of QuickCheck generators.
Building
mvn clean installUsage
Include in your project a class named *Generators.java with a set of public static methods returning Generator instances:
package com.theoryinpractise.quickcheckng.example;
import com.theoryinpractise.quickcheckng.DataProviders;
import net.java.quickcheck.Generator;
import static net.java.quickcheck.generator.CombinedGenerators.uniqueValues;
import static net.java.quickcheck.generator.PrimitiveGenerators.strings;
@DataProviders
public class PasswordGenerators {
public static Generator<String> validPasswords() {
return strings("ABCDEFG123456", 6, 60);
}
}When compiling, the following class will be generated for you:
package com.theoryinpractise.quickcheckng.example;
import java.util.Iterator;
import org.testng.annotations.DataProvider;
import static com.theoryinpractise.quickcheckng.testng.GeneratorProvider.toObjectArrayIterator;
public final class PasswordGeneratorsDataProviders {
/**
* A TestNG @DataProvider for the validPasswords quickcheck generator
*/
@DataProvider
public static final Iterator<Object[]> validPasswords() {
return toObjectArrayIterator(PasswordGenerators.validPasswords());
}
}The generated @DataProvider method simply wraps the QuickCheck Generator, wrapping each generated value in a 1 element object array to be passed to a TestNG test:
@Test(dataProviderClass = PasswordGeneratorsDataProviders.class, dataProvider = "validPasswords")
public void testPasswordLengths(String password) {
try {
UserManagerImpl.validatePassword(password);
} catch (SmxValidationFailureException e) {
fail("Valid length password should not fail: " + password + " - " + e.getMessage());
}
