Scala or Java equivalent of Ruby factory_girl or Python factory_boy (convenient factory pattern for unit testing)
factory-bot, factory-boy, java, scala, unit-testing
Solution
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");`
Problem
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: - factory inheritance and overrides - field defaults and overrides - lazily-computed dependent/derived fields - construction of dependent/related other objects - implicit lazy field dependency resolution 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".
