Java Object transformation to list

[albilu]

Is Java object transformation to list possible??

From the documentation here https://www.datafaker.net/documentation/schemas/#java-object-transformation it seems only singleton is posssible unless i missed something.

Please advise. Here is my iomplementation:

Faker faker = new Faker();

Schema<Object, ?> schema = Schema.of(
                Field.field("name", () -> faker.name().firstName()),
                Field.field("email", () -> faker.internet().emailAddress())
        );

BaseFaker bfaker = new BaseFaker();
Client client = bfaker.populate(Client.class, schema); //Here i would like to have a collection of fake Clients instead

you could use FakeCollection or FakeSequence https://www.datafaker.net/documentation/sequences/
and just use populate as a supplier for these Collection/Sequence
to do it like

List<DefaultPerson> list = new FakeCollection.Builder<DefaultPerson>()
            .suppliers(() -> Faker.populate(DefaultPerson.class)).generate();

        System.out.println(list);

so in your case it could be something like

Faker faker = new Faker();

Schema<Object, ?> schema = Schema.of(
                Field.field("name", () -> faker.name().firstName()),
                Field.field("email", () -> faker.internet().emailAddress())
        );

BaseFaker bfaker = new BaseFaker();
List<Client> list = new FakeCollection.Builder<Client>()
            .suppliers(() -> Faker.populate(Client.class, schema)).len(<min>, <max>).generate();

@snuyanzin Thanks for the feedback.
Issue now is the Client objects have the same fields values. Goal is to have random value for each instance.

List<Client> client = new FakeCollection.Builder<Client>().suppliers(()
                -> Faker.populate(Client.class, schema))
                .len(5).generate();

client2.forEach((t) -> {
            System.out.println(t.getName() + " " + t.getEmail());

        });

Output

Hellen [email protected]
Hellen [email protected]
Hellen [email protected]
Hellen [email protected]

Although it works with simple Collection generation

List<String> names = 
    faker.collection(
            () -> faker.name().firstName(), 
            () -> faker.name().lastName())
        .len(5)
        .generate();

Output

Corkery
Otha
Moore
Tisa
Sawayn

Can you share the complete code snippet?

Hi @albilu , could you give the snapshot release a try?
