podam's Issues

Consider using Sprint Integration to manufacture types

As a Podam maintainer I want types to be manufactured by specialised classes so as to obtain the lowest possible coupling and the highest possible cohesion

Podam doesn't support @NotEmpty and @NotBlank annotation from bean validation from Jakarta EE 8

Adding a @NotNull annotation to a Pojo attribute causes Podam not to fill that value. Although it's impossible to guarantee that Podam will create a value for an attribute annotated with @NotNull, e.g. for non-instantiable types, when a field is annotated with @NotNull Podam should behave as if that field was not annotated, e.g. follow default behaviour, which is to fill the possible fields with values anyway. This behaviour should also be documented because users must know that if they annotate a non instantiable attribute with @NotNull, validation will fail.

Add functionality for mock JPA\Hibernate entities.

Is it possible to add functionality that recognizes JPA annotations and build Entity graph.

Exclude attributes without using annotations

It would be nice to provide a mechanism where excluded attributes could be provided by the strategy without having to annotate them, perhaps by returning excluded attribute names.

addSpecific method in AbstractRandomDataProviderStrategy does not add a specif class to an abstract one, it sets one.

Since specificTypes is if of type Map<Class<?>, Class<?>, every time you put something in it, it overwrites any previous insertions.
So for example, if I have this:
myFactory.addSpecific(MyAbstractClass.class, MyFirstSpecificClass.class);
myFactory.addSpecific(MyAbstractClass.class, MySecondSpecificClass.class);

The second invocation of the method overwrites the first, and MyAbstractClass has only one concrete implementation added to it - the second one.

I think specificTypes should be of type Map<Class<?>, List<Class<?>>>.

podam are slow with objects with lists

With last versions the time to fill some objects with lists are very slow.
Now 21.262 sec
Before 3.123 sec

some mode to set default max limits in lists?

In the presence of multiple constructors (default + full), give users the ability to choose which one to use

Podam should be intelligent enough to try the fullest constructor first, then if that doesn’t work, it should try the one with less arguments and so on until, if none of the other constructors work, it will choose the default one.

Example:

1: BigInteger(int bitLength, int certainty, Random rnd)

2: BigInteger(int signum, byte[] magnitude)
BigInteger(int numBits, Random rnd)
BigInteger(String val, int radix)

3: BigInteger(byte[] val)
BigInteger(String val)

Podam should start with 1. If it can’t build, the first constructor within 2 that succeeds should be used. If that doesn’t work, the fist constructor within 3 should be used and so on until the last choice should be the default constructor (if it exists). This is a very good test case that we should be writing when implement this strategy. The test cases should demonstrate Podam’s ability to “scale down” to the most useful (fullest) constructor up to the point the default constructor will be chosen (last choice).

Regards,
M.

PodamParameterizedType is only used in tests?

PodamParameterizedType is in the main code, but I can only find it being used in tests. Is it part of the implementation, or just a test support class?

Impossible to exclude fields by name

After commit 1c10708 it's impossible to exclude fields by name ass setter for exclusion names was removed.

depth always reset

podam-5.3.1.RELEASE
/uk/co/jemos/podam/api/PodamFactoryImpl.java:1839

    Integer depth = pojos.get(realAttributeType);
            if (depth == null) {
                depth = -1;
            }
            if (depth <= strategy.getMaxDepth(pojo.getClass())) {

                pojos.put(realAttributeType, depth + 1);, //<-- increment depth

                attributeValue = this.manufacturePojoInternal(
                        realAttributeType, attributeMetadata, pojos, genericTypeArgsAll);
                pojos.put(realAttributeType, depth);//<-- put -1 again

            }

PodamFactoryImpl suffers from some serious God class syndrome

PodamFactoryImpl badly needs deconstructing into different classes, and it's methods broken down into smaller steps. The way it is now, it's very hard to maintain.

StackOverflowError when 2 classes reference each other

Hi,
When I try to manufacture pojo1 which contains pojo2 which contains pojo1, it throws a StackOverflowError. Maybe it is not an issue but I didn't find a way to prevent it.

There is a gist with unit test : https://gist.github.com/ludochane/5153343

Relax the POJO definition a bit to handle special cases of mocking needs

We often deal with classes that are not POJOs in the strict sense of the word, but can very well be argued as ones.

Here's an example:

public class SpecialPojo {
  private static class Holder {
    private String holdingString;
    private long holdingLong;
  }

  private Holder myHolder;

  public SpecialPojo() {
    myHolder = new Holder();
  }

  public String getMyString() {
    return myHolder.holdingString;
  }

  public void setMyString(String myString) {
    myHolder.holdingString = myString;
  }

  public long getMyLong() {
    return myHolder.holdingLong;
  }

  public void setMyLong(long myLong) {
    myHolder.holdingLong = myLong;
  }
}

One would think this is one of the good, if not best, candidates PODAM could weave its magic on to create a mock object with arbitrary values. But unfortunately, PODAM won't fill this object with values since it doesn't strictly adhere to Java Bean standards. If PODAM was any less strict to not expect an explicit instance field matching the setter/getter, we'd have had an easier time mocking this type. These lines from the PodamUtils.java are what holding PODAM from being able to mock it:

public static ClassInfo getClassInfo(Class<?> clazz, 
    Set<Class<? extends Annotation>> excludeFieldAnnotations) {
  Set<String> classFields = getDeclaredInstanceFields(clazz, excludeFieldAnnotations);
  Set<Method> classSetters = getPojoSetters(clazz, classFields);
  return new ClassInfo(clazz, classFields, classSetters);
}

Can PODAM be enhanced to relax its definition of POJO a bit so it will be able to handle such special cases of types that need mocking?

Invoking full data manufacturing on Podamfactory doesn't invoke full data manufacturing on External factory

If someone invokes manufacturePojoWithFullData on Podamfactory and specifies an external factory as well, if Podam has to invoke the external factory, it doesn't invoke manufacturePojoWithFullData, rather manufacturePojo.

allow the annotation to be used on getters

The major usage of random initialized objects is for testing, (I personally think) it's not a good idea to put podam annotation into pojos. If it allows to put the annotations on getters, the following would be possible:

class PetProxy extends Pet {

    // podam annotation
    public String getName() {... };
}

What do you think?

Separate Annotations and Implementation into separate jars

It would be nice to be able to have only the annotations on the production classpath, importing the actual implementation logic on the test classpath only.

Limit max string length for @Size

There is an issue with generation String fields marked Size annotation with only min value parameter.

@Size(min = 1)
private String name;

In such case max value parameter is Integer.MAX_INT, so BeanValidationStrategy tries to create string with length [min, Integer.MAX_INT]. This action usually ends up with OOM exception.
Is it possible to limit max length of generated string by some reasonable constant (10 for example)?
Or maybe there is some other way to overcome this problem without modifying source code of domain objects (can't use PodamStringValue annotation or add max parameter)?

fields without setters, including fields that are collections

I have some changes to share back.

This includes a few small bug fixes, but more importantly (1) the processing of fields which do not have setters, (2) using the instantiated pojo when fetching instances of collections from a field, rather than instantiating a new object with a no-arg constructor or such, (3) some JUnit tests.

Can't make it work with Guava's Optional type

Need a way to register a factory for Optional types, or more generally, a way to register a factory for any given type would be better than nothing. This is without having to modify the original class too.

Trying to fill data in a property of an interface type

Hey guys:

Love the plugin. I'm trying to fill data in this object https://github.com/spring-projects/spring-security-oauth/blob/master/spring-security-oauth2/src/main/java/org/springframework/security/oauth2/provider/client/BaseClientDetails.java. However, as you can see there's a property called authorities of type _GrantedAuthority_ (line 69). This type is an interface and whenever I try to create the object with factory.manufacturePojo I get the issue that it's not able to instantiate an interface (which is understandable.). Is there a way to supply to _PodamFactory_ that whenever it encounters that interface, it should use a specific base class to instantiate?

Investigate the possibility to use Dynamic proxies to pass AttributeMetadata to data strategies

Goals:

Have the DataProviderStrategy methods free of the AttributeMetadata
Allow users to define a custom DataProviderStrategy whose methods will be passed an AttributeMetadata through a dynamic proxy. So when DataProviderStrategy methods are invoked, the dynamic proxy can invoke another implementation which receives AttributeMetadata as argument

Improve code coverage

Please refer to coverage report. A number of paths haven't been tested

Hi, thank you for your library, its so helpful in unit testing.
However, I noticed problem with using boolean fields:
I try to generate class using podamFactory.manufacturePojo(Test.class);

i have class:

public class Test{
private boolean visible;

public boolean setVisible(boolean visible){this.visible = visible;}
public boolean isVisible(){ return visible;}
}

There are also other fields, with other types, but boolean fields causes problem:
java.lang.NoSuchMethodException - no getter for field Visible.
I see framework is trying to use getVisible - but for booleans i use isFieldName

I could not find similar issue, if it is not valid, please let me know

Improve AttributeMetaData object

In order to create strategies without annotate our POJOs with Podam annotations, it would be interesting to have access to class type in AttributeMetaData.

Today, AttributeMetaData contains only:

annotations
attribute type
attribute name

Podam doesn't handle whildcard generics with JDK1.7

import java.util.List;

import uk.co.jemos.podam.api.PodamFactory;
import uk.co.jemos.podam.api.PodamFactoryImpl;

public class PodamTest {

public class Pojo {
    private List<? extends Object> objs;

    public List<? extends Object> getObjs() {
        return objs;
    }

    public void setObjs(List<? extends Object> objs) {
        this.objs = objs;
    }

    @Override
    public String toString() {
        return "{objs: '" + objs + "'}";
    }
}

public static void main(String[] args) {
    PodamFactory factory = new PodamFactoryImpl();
    Pojo pojo = factory.manufacturePojo(Pojo.class);
    System.out.println(pojo);
}

}

This small test results in the following exception:

ClassNotFoundException in Play! framework application

I'm trying to use PODAM in a Play! framework (http://www.playframework.org) application.
I know that Play! internal mecanism is none of your business, but you might shed some light on the issue I face.

A simple test with two POJOs works fine in a regular Maven java project : cf. https://github.com/Fluor/podamtest.
To reproduce :

clone repository
mvn test.

The test with same POJOs classes in a Play! application raises ClassNotFoundException : cf. https://github.com/Fluor/podamplaytest
To reproduce and see ClassNotFoundException :

install Play! latest 1.2.4
clone repository
play test
access http://localhost:9000/@tests

I know that Play! use dynamic bytecode generation, which might be the root of this issue.
Have you ever used Play! framework and faced this issue?

Thanks in advance.
Feel free to close this issue as it might not be a PODAM issue.

Memoization should be set to false by default

It provides benefits to have different data in your POJO even at cost of performance.

Unused fields in AbstractRandomDataProviderStrategy.addAttributeStrategy() and AbstractRandomDataProviderStrategy.addSpecific(). The Javadoc for these two methods is incorrect as does not specify a correct contract.

Calling AbstractRandomDataProviderStrategy.addAttributeStrategy() and AbstractRandomDataProviderStrategy.addSpecific() has no effect if there is already mapping or attribute strategy present.

Despite JavaDocs specifies correct behavior:
http://mtedone.github.io/podam/apidocs/uk/co/jemos/podam/api/AbstractRandomDataProviderStrategy.html#addSpecific-java.lang.Class-java.lang.Class-

podam/src/main/java/uk/co/jemos/podam/api/AbstractRandomDataProviderStrategy.java

Line 540 in cf7d7fd

public <T> AbstractRandomDataProviderStrategy addSpecific(

podam/src/main/java/uk/co/jemos/podam/api/AbstractRandomDataProviderStrategy.java

Line 598 in cf7d7fd

public AbstractRandomDataProviderStrategy addAttributeStrategy(

Both methods define unused variable aClass and attributeStrategyClass

Class<?> aClass = specificTypes.putIfAbsent(abstractClass, specificClass);
if (null == aClass) {
    aClass = specificClass;
}

Class<AttributeStrategy<?>> attributeStrategyClass = attributeStrategies.putIfAbsent(annotationClass, strategyClass);
if (null == attributeStrategyClass) {
    attributeStrategyClass = strategyClass;
}

PodamFactoryImpl: Support for XML Datatype instantiation.

Thank you for Podam. I use it in production to generate samples requests for web service APIs. These POJOs often contain XmlGregorianCalendar properties. Here is a patch for PodamFactoryImpl to return values when instantiation requires the use of the XML Datatype factory.

Here are the imports ...

import java.util.GregorianCalendar;
import javax.xml.datatype.DatatypeConfigurationException;
import javax.xml.datatype.DatatypeFactory;
import javax.xml.datatype.Duration;
import javax.xml.datatype.XMLGregorianCalendar;

A helper method to get a static instance of the XML DatatypeFactory...

// A factory to create objects that map XML to/from Java.
private static DatatypeFactory xmlDatatypeFactory;
public static DatatypeFactory getXmlDatatypeFactory()
{
    if ( xmlDatatypeFactory == null )
    {
        try
        {
            xmlDatatypeFactory = DatatypeFactory.newInstance();
        }
        catch (DatatypeConfigurationException e)
        {
            throw new RuntimeException("Podam factory cannot create XML factory.", e);
        }
    }
    return xmlDatatypeFactory;
}

In the createNewInstanceForClassWithoutConstructors(...) method, within the test for 'no constructors' and after the loop to find a 'getInstance()' method, add this code...

// Did we find a getInstance() method to create the return value? 
if ( retValue == null )
{
    // No return value, so far.
    // Can we use an XML DatatypeFactory to create an instance? 
    if ( XMLGregorianCalendar.class.isAssignableFrom(clazz) )
    {
        retValue = getXmlDatatypeFactory().newXMLGregorianCalendar(new GregorianCalendar());
    }
    else if ( Duration.class.isAssignableFrom(clazz) )
    {
        List<Annotation> annotations = new ArrayList<Annotation>();
        getLongValueWithinRange(annotations, null);
        retValue = getXmlDatatypeFactory().newDuration(0L);
    }
}

And a suggestion: Change the log.info(...) in PodamFactoryImpl to log.debug(...). This would allow my SysAdmin to set the log level to INFO instead of WARN without a flood of details from this class, IMHO.

manufacturing a DataHandler object create infinite loop

Hi,
I tried to manufacture a DataHandler object(http://docs.oracle.com/javase/7/docs/api/javax/activation/DataHandler.html) but i incurred in infinite loop.
Infact if i tried to execute this code, program never stops:

public static void main( String[] args ) throws MalformedURLException
    {
        BasicConfigurator.configure();
        PodamFactory factory = new PodamFactoryImpl();
        DataHandler myPojo = factory.manufacturePojo(DataHandler.class);
        System.out.println(myPojo.toString());
    }

These are just several of infinite log lines for my little program :P

Now that the travis file is merged, @mtedone you need to enable travis for your github account. @daivanov and I both have already for our forks.

I want Podam to return the current time when producing java.time.LocalDateTime

Just tried getting Podam to generate LocalDateTime.java objects (new Java 8) and I'm having some problems. Tried using an ExternalFactory without any luck (seeing strange runtime issues). Only thing that works right now is @PodamStrategyValue.

Problem with Log4j2

With the version 5.5.1.RELEASE when you use log4 1.2.17 we have a problem.
The tests read log4j2.xml from podam jar and not use 1.2.17 configuration.
We try exclude log jars from podam dependency but the tests say "not found LogManager" from org.apache.logging.log4j

https://logging.apache.org/log4j/2.x/log4j-api/apidocs/org/apache/logging/log4j/LogManager.html

We move to 5.4.1.RELEASE and this version is Ok

Make Podam thread-safe

Multiple instances of Podam must be able to run within the same JVM without affecting each other's results.

To the question of finding the best constructor for POJO

Podam unit tests behave differently in JDK6 and JDK7. In JDK6 for BigInteger creation
BigInteger(int numBits, Random rnd)
is picked up, however, in JDK7
BigInteger(int bitLength, int certainty, Random rnd)
is found first. The latter is really heavy call causing unit tests to do a heavy work for many minutes.

Trying to deal with this problem, I introduced a sorting for POJO constructors, in such a way, that constructors with Podam annotations will be tried first and then, if not successful, constructors with less parameters will be used. The rationale behind the change is so that in general mocking less parameters should be easier
daivanov@260dc62

However, I do understand that constructors with less parameters do not guarantee success, as meaning of parameters is not known to Podam.

Another point is that sorting will make Podam behave more predictable with different JDK versions.

Move the setNumberOfCollectionElements to interface and refactor accordingly

Pdm4PojoUnitTest fails on jdk7

While working on my fork, #24, I found that Pdm4PojoUnitTest fail on jdk7. You can see the build results here:
https://travis-ci.org/astubbs/podam/builds/14044898
Where it passes on jdk6 but fails on jdk7.

PodamFactoryImpl: Support for JAXBElement instantiation

Classes generated by the JAXB compiler, xjc, produces properties that may include a JAXBElement<T> wrapper. This wrapper is used to encapsulate information related to the XML schema such as the QName (namespace + element name), etc. The wrapper stores the actual property value in its own getValue() / setValue(...) property. Here is a patch for the manufactureAttributeValue method of the PodamFactoryImpl class to create the wrapper and generate a mock of the actual type. It is located just ahead of the exitsing test for "java" and "javax" classes.

import javax.xml.bind.JAXBElement;
import javax.xml.namespace.QName;
...
if ( realAttributeType.getName().startsWith("javax.xml.bind.JAXBElement"))
{
    @SuppressWarnings("unchecked")
    Class<Object> declaredType = (Class<Object>) genericTypeArgs[0];
    String namepaceURI = pojoClass.getPackage().getName();
    QName name = new QName(namepaceURI, attributeName);
    Object value = manufactureAttributeValue(pojoClass, pojos, declaredType, 
        annotations, attributeName, new Type[0]);
    attributeValue = new JAXBElement<Object>(name, declaredType, value);
}

Ability to exclude classes of methods.

With Jackson, it is possible to configure it to only serialize fields (or only getters/setters), see this SO question for example: http://stackoverflow.com/questions/7105745/how-to-specify-jackson-to-only-use-fields-preferably-globally

This does not seem to be possible with the current version of PODAM. Having the ability to specify exclusions rules would be really nice and would allow PODAM to be used with a much larger classes of objects than just basic DTOs/beans/dumb storage classes.

I think this will also solve #80.
