在 Axon-SpringBoot 应用程序中,我有一个聚合,它在某些命令处理程序中使用注入(inject)的 DAO。
例如:
@Aggregate
class MyAggregate {
@CommandHandler
public MyAggregate (CreateMyAggregateCommand command, @Autowired MyAggregateDao dao) {
final SomeProperty = command.getSomePoprtery();
if (dao.findBySomeProperty(someProperty) == null) {
AggregateLifeCycle.apply(
new MyAggregateCreatedEvent(command.getIdentifier(),
someProperty);
} else {
// Don't create, already exits with some property
// report ...
}
}
}
像这样的标准测试
@Test
void creationSucceeds () {
aggregateTestFixture = new AggregateTestFixture<>(MyAggregate.class);
final CreateMyAggregateCommand command = new CreateMyAggregateCommand(...);
final MyAggregateCreatedEvent = new MyAggregateCreatedEvent(...);
aggregateTestFixture
.givenNoPriorActivity()
.when(command)
.expectEvents(event);
}
失败:
org.axonframework.test.FixtureExecutionException: No resource of type
[com.xmpl.MyAggregateDao] has been registered. It is required
for one of the handlers being executed.
我如何提供测试实现?
最佳答案
解决方案1:模拟
由于这是关于单元测试并且我的问题涉及数据库调用(外部服务),因此只要测试仅涉及孤立的聚合行为,模拟似乎就适用。
@Test
void creationSucceeds () {
aggregateTestFixture = new AggregateTestFixture<>(MyAggregate.class);
aggregateTestFixture.registerInjectableResource(
Mockito.mock(MyAggregateDao.class));
}
解决方案 2:真实注入(inject)(jUnit 5)
这个对我有用:
- 从 this github repo 获取用于 Spring jUnit5 测试支持的小型库
注释测试类:
@SpringBootTest(classes = {SpringTestConfig.class}) @ExtendWith(SpringExtension.class) public class MyAggregateTest { // ... }
将 application.properties 放入 src/test/resources
编写启动功能齐全的 Spring 容器的 Spring 测试配置:
@EnableAutoConfiguration public class SpringTestConfig { // Set up whatever you need @Bean @Autowired MyAggregateDao myDao (DataSource dataSource) { // ... } @Bean @Autowired EventStorageEngine eventStorageEngine () { return new InMemoryEventStorageEngine(); } }
直接注入(inject)到您的测试中,配置
AggregateTestFixture
private AggregateTestFixture<MyAggregate> aggregateTestFixture; @Autowired private MyAggregateDao myDao; @BeforeEach void beforeEach () { aggregateTestFixture = new AggregateTestFixture<>(MyAggregate.class); // We still need to register resources manually aggregateTestFixture.registerInjectableResource(myDao); }
使用 jUnit 4
设置一个使用 jUnit 4 启动 Spring 容器的测试配置有点不同,但有足够的文档。开始here
