From b8c1ca531321dbcee3ae237bad20fa8691b31f83 Mon Sep 17 00:00:00 2001 From: Tavian Barnes Date: Sat, 4 Oct 2014 12:24:51 -0400 Subject: contextual: Make ContextSensitiveBinder work with requireExplicitBindings(). Same as regular toProvider() bindings, an explicit binding for the provider is *not* required, unless to provider itself is injected somewhere. This is accomplished by generating a unique linked-key binding for each ContextSensitiveProvider. --- .../contextual/ContextSensitiveBinderTest.java | 21 +++++++++++++++++++++ 1 file changed, 21 insertions(+) (limited to 'sangria-contextual/src/test/java/com/tavianator') diff --git a/sangria-contextual/src/test/java/com/tavianator/sangria/contextual/ContextSensitiveBinderTest.java b/sangria-contextual/src/test/java/com/tavianator/sangria/contextual/ContextSensitiveBinderTest.java index 1e2ab49..68250cb 100644 --- a/sangria-contextual/src/test/java/com/tavianator/sangria/contextual/ContextSensitiveBinderTest.java +++ b/sangria-contextual/src/test/java/com/tavianator/sangria/contextual/ContextSensitiveBinderTest.java @@ -28,6 +28,7 @@ import com.google.inject.Guice; import com.google.inject.Injector; import com.google.inject.Key; import com.google.inject.MembersInjector; +import com.google.inject.Module; import com.google.inject.Provider; import com.google.inject.ProvisionException; import com.google.inject.TypeLiteral; @@ -40,6 +41,7 @@ import org.junit.Rule; import org.junit.Test; import org.junit.rules.ExpectedException; +import static com.tavianator.sangria.test.SangriaMatchers.*; import static org.hamcrest.Matchers.*; import static org.junit.Assert.*; @@ -54,6 +56,10 @@ public class ContextSensitiveBinderTest { public @Rule ExpectedException thrown = ExpectedException.none(); private static class SelfProvider implements ContextSensitiveProvider { + @Inject + SelfProvider() { + } + // For testing getInjectionPoints() in the SPI below @SuppressWarnings("unused") @Inject Injector injector; @@ -191,6 +197,21 @@ public class ContextSensitiveBinderTest { assertThat(hasSelf.selfProvider.get(), equalTo("")); } + @Test + public void testBestPractices() { + Module module = new AbstractModule() { + @Override + protected void configure() { + ContextSensitiveBinder.create(binder()) + .bind(String.class) + .annotatedWith(Names.named("self")) + .toContextSensitiveProvider(SelfProvider.class); + } + }; + assertThat(module, is(atomic())); + assertThat(module, followsBestPractices()); + } + private static class RequiredContextProvider implements ContextSensitiveProvider { @Override public String getInContext(InjectionPoint injectionPoint) { -- cgit v1.2.3
