This class is deprecated.
Use ERROR(/android.support.test.espresso.idling.CountingIdlingResource)
instead.
This class has been moved to a different module to avoid a dependency on espresso-contrib in your
production code. This class will be removed in a future release.
An implementation of IdlingResource
that determines idleness by maintaining an internal
counter. When the counter is 0 - it is considered to be idle, when it is non-zero it is not
idle. This is very similar to the way a Semaphore
behaves.
The counter may be incremented or decremented from any thread. If it reaches an illogical state (like counter less than zero) it will throw an IllegalStateException.
This class can then be used to wrap up operations that while in progress should block tests from accessing the UI.
public interface FooServer {
public Foo newFoo();
public void updateFoo(Foo foo);
public DecoratedFooServer implements FooServer {
private final FooServer realFooServer;
private final CountingIdlingResource fooServerIdlingResource;
public DecoratedFooServer(FooServer realFooServer,
CountingIdlingResource fooServerIdlingResource) {
this.realFooServer = checkNotNull(realFooServer);
this.fooServerIdlingResource = checkNotNull(fooServerIdlingResource);
}
public Foo newFoo() {
fooServerIdlingResource.increment();
try {
return realFooServer.newFoo();
} finally {
fooServerIdlingResource.decrement();
}
}
public void updateFoo(Foo foo) {
fooServerIdlingResource.increment();
try {
realFooServer.updateFoo(foo);
} finally {
fooServerIdlingResource.decrement();
}
}
}
}
Then in your test setup:
public void setUp() throws Exception {
super.setUp();
FooServer realServer = FooApplication.getFooServer();
CountingIdlingResource countingResource = new CountingIdlingResource("FooServerCalls");
FooApplication.setFooServer(new DecoratedFooServer(realServer, countingResource));
Espresso.registerIdlingResource(countingResource);
}

Decrements the count of in-flight transactions to the resource being monitored. If this operation results in the counter falling below 0 - an exception is raised.
