We have no success to implement gae junit test.
We use spring 2.5.6 and follow the
http://code.google.com/appengine/docs/java/howto/unittesting.html
.
public class BaseTestCase extends
AbstractDependencyInjectionSpringContextTests {
@Override
public void onSetUp() throws Exception {
ApiProxy.setEnvironmentForCurrentThread(new
TestEnvironment());
ApiProxy.setDelegate(new ApiProxyLocalImpl(new File("D:/work/
drp/src/drp/war")){});
super.onSetUp();
}
@Override
public void onTearDown() throws Exception {
super.onTearDown();
// not strictly necessary to null these out but there's no
harm either
ApiProxy.setDelegate(null);
ApiProxy.setEnvironmentForCurrentThread(null);
}
public String[] getConfigLocations() {
String[] configLocations = { "file:war/WEB-INF/
applicationContext.xml" };
return configLocations;
}
}
but when run junit test. the exception is throw
Failed to load from the backing store, D:\work\drp\src\drp\war\WEB-INF
