How can I gracefully shut down a Spring Boot application after an integration test when @SpringBootTest does not properly terminate the application?
I’m running integration tests for a Spring Boot application. After the tests finish, the application does not automatically shut down when using the @SpringBootTest annotation, and I have to manually kill the process.
My environment:
- Spring Boot v: 2.6.2
- JUnit v: 5.8.1
- Java v: 17
Example:
@SpringBootTest
public class MyIntegrationTest {
@Test
public void testSomething() {
// Test code
}
}
Attempts:
- Explicitly shut down the Spring application using `SpringApplication.exit()`.
- Using the `@DirtiesContext `annotation.
What could be causing the application to not shut down automatically after the tests, and how can I gracefully resolve this issue? Are there any specific configuration settings or code implementations that I should consider?
It can be caused because of any long-running resources(active threads, db connections… etc) or test configuration issues. Custom configurations or listeners could interfere with the normal shutdown process. Another reason can be with the @SpringBootTest context management or an incorrect @DirtiesContext.
One way to shutdown is to use in a @AfterEach method:
@SpringBootTest
public class MyIntegrationTest {
@Autowired
private ConfigurableApplicationContext applicationContext;
@Test
public void testSomething() {
// Test code
}
@AfterEach
public void tearDown() {
if (applicationContext != null) {
applicationContext.close();
}
}
}
Note: Consider upgrading to a newer version of Spring Boot and JUnit if possible. There could be bug fixes and improvements related to application shutdown and test execution.
