为fun JdbcDatabaseContainer<*>.execute(query:DSLContext.()-> Query){
val connection = DriverManager.getConnection(this.getJdbcUrl(),this.getUsername(),this.getPassword())
val create = DSL.using(connection)
create.query().execute()
}
写了一个简短的方便扩展名：
allDataPresent现在想对其进行测试。
canInsert canInsertWithExtension插入一个不带扩展名的条目insertMultipleWithExtension一样，只是通过扩展功能allDataPresent的名称完全相同，并插入另外5个除@Transactional测试用例（因为无论如何都是只读的）以外的所有内容都被注释[ERROR] Failures:
[ERROR] InitDataIT.allDataPresent:70
Expecting:
<36>
to be equal to:
<30>
but was not.
[ERROR] InitDataIT.canInsert:90
Expecting:
<6>
to be equal to:
<1>
but was not.
[ERROR] InitDataIT.canInsertWithExtension:112
Expecting:
<6>
to be equal to:
<1>
but was not.
。
因此，我希望这些修改可以在测试方法后回滚。
发生的事情是
@Test每个@Transactional都能正常工作。因此问题必须出在@Testcontainers
@SpringBootTest(webEnvironment = SpringBootTest.WebEnvironment.RANDOM_PORT)
@ContextConfiguration(initializers = [InitDataIT.TestContextInitializer::class])
@AutoConfigureTestDatabase(replace = AutoConfigureTestDatabase.Replace.NONE)
open class InitDataIT {
companion object {
@JvmStatic
@Container
private val dbContainer = MySQLContainer<Nothing>().apply {
withDatabaseName("test")
withUsername("root")
withPassword("")
}
}
object TestContextInitializer: ApplicationContextInitializer<ConfigurableApplicationContext> {
override fun initialize(applicationContext: ConfigurableApplicationContext) {
TestPropertyValues.of(
"spring.datasource.url=${dbContainer.jdbcUrl}",
"spring.datasource.username=${dbContainer.username}",
"spring.datasource.password=${dbContainer.password}",
"spring.datasource.driver-class-name=${dbContainer.driverClassName}"
).applyTo(applicationContext)
}
}
private val create:DSLContext
@Autowired
constructor(create:DSLContext){
this.create = create
}
@Test
fun allDataPresent(){
//given
val expectedNumberOfEntries = 30
val query = create.selectCount()
.from(CUSTOMERS)
//when
val numberOfEntries = query.fetchOne{it.value1()}
//then
Assertions.assertThat(numberOfEntries).isEqualTo(expectedNumberOfEntries)
}
@Test
@Transactional
open fun canInsert(){
//given
val insertquery = create.insertInto(CUSTOMERS)
.columns(CUSTOMERS.FIRSTNAME,CUSTOMERS.LASTNAME,CUSTOMERS.EMAIL, CUSTOMERS.STATUS)
.values("Alice","Tester","Alice.Tester@somewhere.tt",CustomerStatus.Contacted.name)
val expectedNumberInOffice2 = 1
//when
insertquery.execute()
//then
val numberInOffice2 = create.selectCount()
.from(CUSTOMERS)
.where(CUSTOMERS.EMAIL.contains("somewhere"))
.fetchOne{it.value1()}
assertThat(numberInOffice2).isEqualTo(expectedNumberInOffice2)
}
@Test
@Transactional
open fun canInsertWithExtension(){
//given
dbContainer.execute {
insertInto(CUSTOMERS)
.columns(CUSTOMERS.FIRSTNAME,CUSTOMERS.LASTNAME,CUSTOMERS.EMAIL, CUSTOMERS.STATUS)
.values("Alice","Tester","Alice.Tester@somewhere.tt",CustomerStatus.Contacted.name)
}
val expectedNumberInOffice2 = 1
//when
val numberInOffice2 = create.selectCount()
.from(CUSTOMERS)
.where(CUSTOMERS.EMAIL.contains("somewhere"))
.fetchOne{it.value1()}
//then
assertThat(numberInOffice2).isEqualTo(expectedNumberInOffice2)
}
@Test
@Transactional
open fun insertMultipleWithExtension(){
//given
dbContainer.execute {
insertInto(CUSTOMERS)
.columns(CUSTOMERS.FIRSTNAME,CUSTOMERS.LASTNAME,CUSTOMERS.EMAIL, CUSTOMERS.STATUS)
.values("Alice","Make","Alice.Make@somewhere.tt", CustomerStatus.Customer.name)
.values("Bob","Another","Bob.Another@somewhere.tt", CustomerStatus.ClosedLost.name)
.values("Charlie","Integration","Charlie.Integration@somewhere.tt",CustomerStatus.NotContacted.name)
.values("Denise","Test","Denise.Test@somewhere.tt",CustomerStatus.Customer.name)
.values("Ellie","Now","Ellie.Now@somewhere.tt",CustomerStatus.Contacted.name)
}
val expectedNumberInOffice2 = 5
//when
val numberInOffice2 = create.selectCount()
.from(CUSTOMERS)
.where(CUSTOMERS.EMAIL.contains("somewhere"))
.fetchOne{it.value1()}
//then
assertThat(numberInOffice2).isEqualTo(expectedNumberInOffice2)
}
}
上。
那为什么呢？更重要的是，我如何获得回滚？
完整的测试用例（也尝试对类进行注释，没有任何区别）：
(\d{2}\s\d{2}\s\d{4})
答案 0 :(得分：2)
Spring import {
createMaterialTopTabNavigator,
createStackNavigator
} from 'react-navigation'
import MyComponent from '../some-component-folder/'
import MyHomeComponent from '../some-component-folder/'
import MyNavigator from '../some-navigator-folder/'
const TabNavigator = createMaterialTopTabNavigator(
{
Tab1: { screen: MyComponent }
Tab2: { screen: MyNavigator }
}
)
const StackNavigator = createStackNavigator(
{
Screen1: { screen: MyHomeComponent }
Screen2: { screen: TabNavigator }
}
)
注释不仅可以神奇地与您创建的forum.txtbox.Focus
JDBC连接配合使用。您的@Transactional对象应该在您的Spring托管数据源上运行。
