I hope someone can help as I'm starting to pull my hair out. I'm using
a Guice module in the class I'm testing to return back some instances
of lists. Guice injects the types in the list. Anyway, here is a
snippet of the code in the class I'm testing:
Injector srcInjector = Guice.createInjector(new
SourcesModule(serverProps));
inputSources = srcInjector.getInstance(Key.get(new TypeLiteral
<List<InputSourceStringImpl>>(){}));
outputSources = srcInjector.getInstance(Key.get(new TypeLiteral
<List<OutputSourceStringImpl>>(){}));
I need to be able to override the SourcesModule to inject some mock
sources for proper testing. I've tried the following in my tests but
the override is not working as the sources are still injected by
SourcesModule:
Injector injector = Guice.createInjector( new AbstractModule(){
@Override
protected void configure() {
bind(new
TypeLiteral<List<String>>() {}).toInstance(servers);
bind(ListenerDAO.class).to(MockDAO.class);
bind(new
TypeLiteral<List<ServerProperties>>()
{}).toInstance(listDefaultServerProperties);
}
}
,Modules.override(new
SourcesModule(Arrays.asList(defaultServerProperties))).with(
new AbstractModule(){
@Override
protected void
configure() {
}
@SuppressWarnings("unused")
@Provides
private
List<InputSourceStringImpl> provideInputSources(){
return
injectedInputs;
}
}));
ListenerController controller =
injector.getInstance(ListenerController.class);
injectedInputs is a List of my mock sources.
Am I just going about the override incorrectly or is my implementation
of Guice with the SourcesModule incompatible with testing? Any help
would be appreciated.
Thanks,
Carl.
