So how do we do it?pom.xml:

(junit 4.4) spring-core spring-beans

spring-test

spring-tx

265 + 451 + 216 + 174 = 1,1 MB

How?

@RunWith(SpringJUnit4ClassRunner.class)

@ContextConfiguration(locations = { "testSpring.xml" })

public class TestJUnit4WithSpringTestContextFramework {

...

Repeat@Test

@Repeat(20)

public void repeatManyTimes() throws Exception {

counter++;

int numberOfTimesToRepeat = this.

getClass().

getMethod("repeatManyTimes").

getAnnotation(Repeat.class).value();

log.trace("Running for the "+counter+"th time");

if (counter > numberOfTimesToRepeat) {

fail(

"Should not repeat more than 100 times. counter is "+counter);

}

}

Caching av contexts

// can't really come up with anything that screws the context here..

JUnit4 exception testing

/**

Then the real fun begins..

• Use Spring’s data factories – Inject with @Autowired

• @ContextConfiguration

• Transaction testing

• Kan bygges videre på med egne @TestExecutionListeners

• Uendelige muligheter!
