Data-driven tests with jUnit

Question

What do you use for writing data-driven tests in jUnit?

(My definition of) a data-driven test is a test that reads data from some external source (file, database, ..

Answer 1

Even though this is quite an old topic, i still thought of contributing my share. I feel JUnit's support for data driven testing is to less and too unfriendly. for eg. in order to use parameterized, we need to write our constructor. With Theories runner we do not have control over the set of test data that is passed to the test method.

There are more drawbacks as identified in this blog post series: http://www.kumaranuj.com/2012/08/junits-parameterized-runner-and-data.html

There is now a comprehensive solution coming along pretty nicely in the form of EasyTest which is a a framework extended out of JUnit and is meant to give a lot of functionality to its users. Its primary focus is to perform Data Driven Testing using JUnit, although you are not required to actually depend on JUnit anymore. Here is the github project for refernece: https://github.com/anujgandharv/easytest
