运行 使用 Micronaut 应用程序在 JUnit5 中对每个 Unit/Integration 测试进行一次 TestContainer
Running TestContainer once for each Unit/Integration test in JUnit5 with Micronaut application
我在 Micronaut 应用程序中使用带有 JUnit 5 的测试容器。我有很多集成测试,我想为每个集成测试创建并 运行 一次测试容器。
**对不同文件的第一次测试**
@TestInstance(TestInstance.Lifecycle.PER_CLASS)
@MicronautTest
public class DiscountGetListenerTest extends TestContainerFixture {
@Inject
static IDiscountProducer iDiscountProducer;
@Test
@DisplayName("Should return the discount based on the specified id")
void shouldReturnTheDiscountBasedOnTheSpecifiedId() {
}
}
对不同文件的第二次测试
@TestInstance(TestInstance.Lifecycle.PER_CLASS)
@MicronautTest
public class DiscountListenerTest extends TestContainerFixture {
@Inject
IDiscountProducer iDiscountProducer;
@Test
@DisplayName("Should return discounts list")
void shouldReturnDiscountsList() {
var item = iDiscountProducer.Find(new DiscountCriteriaCommand(null)).blockingGet();
assertTrue(item.size() == 0);
}
}
测试容器夹具
@Testcontainers
public class TestContainerFixture {
@Container
public GenericContainer mongoDBContainer = new GenericContainer(DockerImageName.parse("mongo:4.0.10"))
.withExposedPorts(27017);
@Container
public GenericContainer rabbitMQContainer = new GenericContainer(DockerImageName.parse("rabbitmq:3-management-alpine"))
.withExposedPorts(5672);
}
当我 运行 应用程序在每个集成测试中创建并启动容器时,但是,我想创建一次并启动一次容器
例如
在每个测试用例中创建并启动容器...我怎样才能创建并启动一次容器??
也许你可以尝试这里解释的单例容器模式:https://www.testcontainers.org/test_framework_integration/manual_lifecycle_control/
所以对于您的代码:
public abstract class TestContainerFixture {
public static final GenericContainer mongoDBContainer;
public static final GenericContainer rabbitMQContainer;
static {
mongoDBContainer = new GenericContainer(DockerImageName.parse("mongo:4.0.10"))
.withExposedPorts(27017);
rabbitMQContainer = new GenericContainer(DockerImageName.parse("rabbitmq:3-management-alpine"))
.withExposedPorts(5672);
mongoDbContainer.start();
rabbitMQContainer.start();
}
}
当您在测试中扩展此摘要 class 时,也许会奏效。
