10年前
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) public class SimpleTest { @Rule public Acai acai = new Acai(MyTestModule.class); @Inject private MyClass foo; @Test public void checkSomethingWorks() { // Use the injected value of foo here } private static class MyTestModule extends AbstractModule { @Override protected void configure() { bind(MyClass.class).to(MyClassImpl.class); } } } 使用 Acai 启动服务
@RunWith(JUnit4.class) public class ExampleFunctionalTest { @Rule public Acai acai = new Acai(MyTestModule.class); @Inject private MyServerClient serverClient; @Test public void checkSomethingWorks() { // Call the running server and test some behaviour here. // Any state will be cleared by MyFakeDatabaseWiper after each // test case. } private static class MyTestModule extends AbstractModule { @Override protected void configure() { // Normal Guice modules which configure your // server with in-memory versions of backends. install(MyServerModule()); install(MyFakeDatabaseModule()); install(new TestingServiceModule() { @Override protected void configureTestingServices() { bindTestingService(MyServerRunner.class); bindTestingService(MyFakeDatabaseWiper.class); } }); } } private static class MyServerRunner implements TestingService { @Inject private MyServer myServer; @BeforeSuite void startServer() { myServer.start().awaitStarted(); } } private static class MyFakeDatabaseWiper implements TestingService { @Inject private MyFakeDatabse myFakeDatabase; @AfterTest void wipeDatabase() { myFakeDatabase.wipe(); } } }
