Your Question

im trying to make simple insert database testing, below is my test code

@Testcontainers
@SpringBootTest
@DisplayName("users testing")
@DataMongoTest(excludeAutoConfiguration = EmbeddedMongoAutoConfiguration.class)
class OrderApplicationUsersTests {
	
	@Container
	static MongoDBContainer mongoDBContainer = new MongoDBContainer(DockerImageName.parse("mongo:6.0.3"));

	@DynamicPropertySource
	static void setProperties(DynamicPropertyRegistry registry) {
		registry.add("spring.data.mongodb.uri", mongoDBContainer::getReplicaSetUrl);
	}
	
	private UserRepository userRepo;
	
	private String uriContainer = mongoDBContainer.getIpAddress();
	
	@Test
	@DisplayName("add admin")
	void isertAdmin() throws IOException {
		userRepo.deleteAll();
		URL url = new URL(uriContainer + "/users/admin");
		URLConnection conn = url.openConnection();
		InputStream in = conn.getInputStream();
		String encoding = conn.getContentEncoding();
		encoding = encoding == null ? "UTF-8" : encoding;
		String body = IOUtils.toString(in, encoding);
		MatcherAssert.assertThat(body, CoreMatchers.containsString("admin generated"));
	}
	
	@Test
	@DisplayName("add admin failed")
	void isertAdminTwice() throws IOException {
		URL url = new URL(uriContainer + "/users/admin");
		URLConnection conn = url.openConnection();
		InputStream in = conn.getInputStream();
		String encoding = conn.getContentEncoding();
		encoding = encoding == null ? "UTF-8" : encoding;
		String body = IOUtils.toString(in, encoding);
		MatcherAssert.assertThat(body, CoreMatchers.containsString("admin only generated once"));
	}
