When I am writing unit tests in dynamically-typed Ruby or Python, I use the libraries factory_girl and factory_boy, respectively, in order to conveniently generate objects under test. They provide convenient features over direct object instantiation, for example:
What are some libraries/frameworks I could use while writing unit tests in statically-typed Java or Scala to achieve similar effects with similar benefits?
Thanks in advance!
I found a similar StackOverflow question from the past here, but unfortunately, the top answer is (paraphrased), "there is no direct equivalent because that would be pointless".
There is a project called Fixture-Factory(https://github.com/six2six/fixture-factory). It was based in the Factory-Girl's idea.
You could easily create your object's template definition:
Fixture.of(Client.class).addTemplate("valid", new Rule(){{
add("id", random(Long.class, range(1L, 200L)));
add("name", random("Anderson Parra", "Arthur Hirata"));
add("nickname", random("nerd", "geek"));
add("email", "${nickname}@gmail.com");
add("birthday", instant("18 years ago"));
add("address", one(Address.class, "valid"));
}});
And then you can easily use it in your tests:
Client client = Fixture.from(Client.class).gimme("valid");
