Returning to the previous hello world example, let's change the implementation to log the call using a monitor service:
| Code Block |
|---|
|
public interface HelloWorldMonitor {
void onHello(String name);
}
|
The code for the service implementation class is changed to incorporate the call to the above service:
| Code Block |
|---|
|
public class HelloWorldImpl implements HelloWorld {
@Reference
protected HelloWorldMonitor monitor;
public String sayHello(String name) {
monitor.onHello(name);
return "Hello " + name;
}
}
|
The HelloWorldMonitor can be mocked in the test composite as follows:
| Code Block |
|---|
|
<composite name="TestComposite" targetNamespace="urn:fabric3.org" ...>
<component name="HelloWorldTest">
<f3:junit class="...HelloWorldITest"{color}/>
<reference name="helloWorld" target="HelloWorldComponent"/>
</component>
<component name={color:#378d00}"MockComponent"{color}>
<f3:implementation.mock>
HelloWorldMonitor
</f3:implementation.mock>
</component>
<include name="HelloWorldComposite/>
</composite>
|
...
Once this is setup, the JUnit test component can be modified to use the Easymock API to verify the right number of calls are made to the monitor service by the HelloWorldImpl component.
| Code Block |
|---|
|
public class HelloWorldITest extends TestCase {
@Reference
protected HelloWorld helloWorld;
@Reference
protected IMocksControl control;
@Reference
protected HelloWorldMonitor monitor;
public void testSayHello() {
control.reset();
monitor.onSayHello("Foo");
control.replay();
assertEquals("Hello Foo", helloWorld.sayHello("Fred"));
control.verify();
}
}
|
Before the test is run, be sure to add Easymock as a project dependency and the Fabric3 mock extension to the runtime configuration:
| Code Block |
|---|
