Question

I want to setup my testing database with test data before I start my tests. I suppose I should run that once at the start of the unit tests instead of before each test class for function? How might I do that?

Answer 1

You can achieve that with @SuiteClasses annotation:

@RunWith(Suite.class)
@SuiteClasses({UserDaoTests.class, OrderDaoTests.class})
public class TestSuiteSetup {
    @BeforeClass
    public static void setUpDatabase() {
        // ...
    }

    @AfterClass
    public static void tearDownDatabase() {
        // ...
    }
}

Tests from UserDaoTests and OrderDaoTests will be run between setUpDatabase and tearDownDatabase methods.
