Introducing Spring Framework

Chapter 7 ■ Testing Your Spring Application
Listing 7-2 shows that the tag has an attribute of profile where you can define any environment or any
string as a profile, so in this file you declared two profiles: dev and qa. So you have declared the profile dev that has
the engine and documentDAO beans, and the profile qa that has only the documentDAO bean. But how does the Spring
container know what profile to use? You are going to see that with your test class (see Listing 7-3). Also, you added the
that will search for any annotated class within the com.apress.isf.spring.service
package. This tag will play an important part for your next tests.
Now, let’s create your test class, as shown in Listing 7-3. In this test you will use a new annotation: @ActiveProfiles.
This annotation will tell the Spring container which profile to use and the beans to instantiate for their use.
Listing 7-3. MyDocumentsWithProfilesTest.java
