Interface BeforeClass
public interface BeforeClass
Sometimes several tests need to share computationally expensive setup
(like logging into a database). While this can compromise the independence of
tests, sometimes it is a necessary optimization. Annotating a
public static void
no-arg method
with
@BeforeClass
causes it to be run once before any of
the test methods in the class. The
@BeforeClass
methods of superclasses
will be run before those the current class.
For example:
public class Example {
@BeforeClass public static void onlyOnce() {
...
}
@Test public void one() {
...
}
@Test public void two() {
...
}
}
