I have an integration testing class for mine UserController. The contents of the following class:
@SpringBootTest(webEnvironment = SpringBootTest.WebEnvironment.RANDOM_PORT)
@RunWith(SpringRunner.class)
@Transactional
@Rollback
public class UserControllerTests {
private static final String ENDPOINT = "/v1/users";
@Autowired
private TestRestTemplate restTemplate;
@Autowired
private ApplicationProperties applicationProperties;
@Test
public void test_user_create() {
String token = login("test", "test");
HttpEntity<UserRequest> request = createRequest(token, "admin", "admin");
ResponseEntity<User> response = restTemplate.exchange(ENDPOINT, HttpMethod.POST, request, User.class);
assertEquals(HttpStatus.CREATED, response.getStatusCode());
}
private HttpEntity createRequest(String token) {
HttpHeaders headers = new HttpHeaders();
headers.setAccept(Collections.singletonList(MediaType.APPLICATION_JSON));
headers.set("Authorization", String.format("Bearer %s", token));
return new HttpEntity(headers);
}
private HttpEntity<UserRequest> createRequest(String token, String username, String password) {
HttpHeaders headers = new HttpHeaders();
headers.setContentType(MediaType.APPLICATION_JSON);
headers.setAccept(Collections.singletonList(MediaType.APPLICATION_JSON));
headers.set("Authorization", String.format("Bearer %s", token));
return new HttpEntity<>(new UserRequest(username, password), headers);
}
private String login(String username, String password) {
HttpHeaders headers = new HttpHeaders();
headers.setContentType(MediaType.APPLICATION_FORM_URLENCODED);
headers.setAccept(Collections.singletonList(MediaType.APPLICATION_JSON));
headers.set("Authorization", String.format("Basic %s", Base64.getEncoder().encodeToString(String.format("%s:%s", applicationProperties.getAuth().getClientId(), applicationProperties.getAuth().getClientSecret()).getBytes())));
MultiValueMap<String, String> body = new LinkedMultiValueMap<>();
body.add("grant_type", "password");
body.add("username", username);
body.add("password", password);
HttpEntity<MultiValueMap<String, String>> request = new HttpEntity<>(body, headers);
ResponseEntity<OAuth2AccessToken> response = restTemplate.exchange("/oauth/token", HttpMethod.POST, request, OAuth2AccessToken.class);
return response.getBody().getValue();
}
}
When I run this test class twice, the second time it fails, because there is already a user with a username in the database admin(unique restriction).
I am testing a database postgresthe same as in my production environment. The application uses Spring jdbcTemplatefor database operations.
The following magazines were created in my journal:
2017-10-13 14:11:31.407 INFO [iam-service,,,] 63566 --- [ main] o.s.t.c.transaction.TransactionContext : Began transaction (1) for test context
...
2017-10-13 14:11:32.050 INFO [iam-service,,,] 63566 --- [ main] o.s.t.c.transaction.TransactionContext : Rolled back transaction for test context
My application flow <request> --> <controller> --> <service with jdbcTemplate>, and services - annotation using @Transactional.
I am really stuck with this.
One solution found did not work for me, it created a PlatformTransactionManagerbean for a test configuration:
@Bean
public PlatformTransactionManager transactionManager(DataSource dataSource) {
return new DataSourceTransactionManager(dataSource);
}
