我试图在Spring Boot中运行一些集成测试。为此我相信我们应该在每次测试运行后使用@DirtiesContext
来清理数据库。
我现在尝试了几种方法,但它们都具有相同的效果。
这是我的设置:
这是完整的POM:

@Entity
@Table(name = "log")
internal data class LogEntity(

@GeneratedValue(strategy = GenerationType.AUTO)
@Column(name = "id")

@Column(name = "descriptive_message")
val descriptiveMessage: String = "",

)
@Entity
@Table(name = "log_reference")
internal class LogReferenceEntity(
@Id
@GeneratedValue(strategy = GenerationType.AUTO)
@Column(name = "id")
val id: Long? = null,
@Column(name = "name")
val Name: String = "",
@Column(name = "value")
val value: String = "",
@ManyToOne
@JoinColumn(name = "log_id")
var log: LogEntity? = null)
@Entity
@Table(name = "log_message_content")
internal data class LogMessageContentEntity(
@Id
@GeneratedValue(strategy = GenerationType.AUTO)
@Column(name = "id")
val id: Long? = null,
@Column(name = "message_content")
val messageContent: ByteArray = byteArrayOf(),
@Column(name = "create_date_time")
val createDateTime: LocalDateTime = LocalDateTime.now(),
@OneToOne(cascade = [(CascadeType.ALL)])

var log: LogEntity = LogEntity()
) {
override fun equals(other: Any?): Boolean {
if (this === other) return true
if (javaClass != other?.javaClass) return false
other as LogMessageContentEntity
if (id != other.id) return false
if (!Arrays.equals(messageContent, other.messageContent)) return false
if (createDateTime != other.createDateTime) return false
if (log != other.log) return false
return true
}
override fun hashCode(): Int {
var result = id?.hashCode() ?: 0
result = 31 * result + Arrays.hashCode(messageContent)
result = 31 * result + createDateTime.hashCode()
result = 31 * result + log.hashCode()
return result
}
}
存储库都是非常标准的
@Transactional
internal interface LogRepository : CrudRepository<LogEntity, Long>
@Transactional
internal interface LogReferenceRepository : CrudRepository<LogReferenceEntity, Long>
@Transactional
internal interface LogMessageContentRepository : CrudRepository<LogMessageContentEntity, Long>
我只有一个服务来处理Log实例,它还处理相关的LogReferenceEntity和LogMessageContentEntity对象。
@Service
@Transactional
internal class JpaLogService(
val logRepository: LogRepository,
val logReferenceRepository: LogReferenceRepository,
val logMessageContentRepository: LogMessageContentRepository) : LogService {
override fun retrieveLogs(): List<LogDTO> {
return logRepository.findAll().map { it.toDTO() }
}
override fun retrieveLog(id: Long): LogDTO? {
return logRepository.findOne(id)?.toDTO()
}
override fun addLog(logCreateDTO: LogCreateDTO): LogDTO {
val log = LogEntity.fromDto(logCreateDTO)
// Add a reference to each log instance, and persist to the database
log.references.forEach {reference ->
reference.log = log
logReferenceRepository.save(reference)
}
log.messageContent?.let {
it.log = log
logMessageContentRepository.save(it)
}
return logRepository.save(log).toDTO()
}
}
我只添加了测试类的一部分。
发生的情况是,一旦运行了一个向数据库添加实例的测试,测试完成后就不会删除该实例。在这个例子中,我遗漏了@DirtiesContext
注释,我将在下面展示我尝试过的内容。
@RunWith(SpringRunner::class)
@SpringBootTest
internal class JpaLogServiceTest {
@Autowired
lateinit var service: LogService
@Autowired
lateinit var repository: LogRepository
@Test
fun `'retrieveLogs' should retrieve empty list if repository doesn't contain entities`() {
assertThat(service.retrieveLogs()).isEmpty()
}
@Test
fun `'addLog' should return the created entity`() {
val result = service.addLog(logCreateDTO = LogCreateDTO())
assertThat(result).isNotNull()
assertThat(result.id).isNotNull()
}
}
没有任何参数的类@DirtiesContext
@RunWith(SpringRunner::class)
@SpringBootTest
@DirtiesContext
internal class JpaLogServiceTest {
...
}
在@DirtiesContext
的班级上classMode
@RunWith(SpringRunner::class)
@SpringBootTest
@DirtiesContext(classMode = DirtiesContext.ClassMode.AFTER_EACH_TEST_METHOD)
internal class JpaLogServiceTest {
...
}
@DirtiesContext
关于将实例保存到数据库的测试方法@RunWith(SpringRunner::class)
@SpringBootTest
internal class JpaLogServiceTest {
...
@Test
@DirtiesContext
fun `'addLog' should return the created entity`() {
val result = service.addLog(logCreateDTO = LogCreateDTO())
assertThat(result).isNotNull()
assertThat(result.id).isNotNull()
}
}
@DirtiesContext
关于使用methodMode
@RunWith(SpringRunner::class)
@SpringBootTest
internal class JpaLogServiceTest {
...
@Test
@DirtiesContext(methodMode = DirtiesContext.MethodMode.AFTER_METHOD)
fun `'addLog' should return the created entity`() {
val result = service.addLog(logCreateDTO = LogCreateDTO())
assertThat(result).isNotNull()
assertThat(result.id).isNotNull()
}
}
我也尝试过其他一些东西,但我觉得我并不太远。
有人能给我一个正确的方向吗?
答案 0 :(得分:2)
您不应该使用@DirtiesContext
来清除测试之间的数据库更改,尽管有时可能需要在测试类之间错误地共享应用程序上下文。
相反;您应该将测试标记为@Transactional
。这将确保每个测试方法都被Spring事务包装,无论结果如何都将回滚。
@Test
@Transactional
fun `'addLog' should return the created entity`() {
val result = service.addLog(logCreateDTO = LogCreateDTO())
assertThat(result).isNotNull()
assertThat(result.id).isNotNull()
}
