Acai JUnit4 和 Guice 测试库

Acai 是 JUnit4 和 Guice 的测试库，可以更容易的编写应用功能测试。

主要特性：

注入测试需要的助手类

启动测试需要的任意的服务

运行测试之间的服务清理

按照正确顺序启动多个服务

创建测试作用域绑定

Acai 主要针对的是应用大型功能测试。

安装

<dependency><groupId>com.google.acai</groupId><artifactId>acai</artifactId><version>0.1</version><scope>test</scope></dependency>

使用 Acai 进行测试注入

@RunWith(JUnit4.class)publicclassSimpleTest{@RulepublicAcaiacai=newAcai(MyTestModule.class);@InjectprivateMyClassfoo;@TestpublicvoidcheckSomethingWorks(){//Usetheinjectedvalueoffoohere}privatestaticclassMyTestModuleextendsAbstractModule{@Overrideprotectedvoidconfigure(){bind(MyClass.class).to(MyClassImpl.class);}}}

使用 Acai 启动服务

@RunWith(JUnit4.class)publicclassExampleFunctionalTest{@RulepublicAcaiacai=newAcai(MyTestModule.class);@InjectprivateMyServerClientserverClient;@TestpublicvoidcheckSomethingWorks(){//Calltherunningserverandtestsomebehaviourhere.//AnystatewillbeclearedbyMyFakeDatabaseWiperaftereach//testcase.}privatestaticclassMyTestModuleextendsAbstractModule{@Overrideprotectedvoidconfigure(){//NormalGuicemoduleswhichconfigureyour//serverwithin-memoryversionsofbackends.install(MyServerModule());install(MyFakeDatabaseModule());install(newTestingServiceModule(){@OverrideprotectedvoidconfigureTestingServices(){bindTestingService(MyServerRunner.class);bindTestingService(MyFakeDatabaseWiper.class);}});}}privatestaticclassMyServerRunnerimplementsTestingService{@InjectprivateMyServermyServer;@BeforeSuitevoidstartServer(){myServer.start().awaitStarted();}}privatestaticclassMyFakeDatabaseWiperimplementsTestingService{@InjectprivateMyFakeDatabsemyFakeDatabase;@AfterTestvoidwipeDatabase(){myFakeDatabase.wipe();}}}
