WireMock WireMockRule Sınıfı - JUnit4 İçindir

Örnek

Şöyle yaparız

@Rule
public WireMockRule wireMockRule = new WireMockRule(int port);

Açıklaması şöyle

We can integrate a WireMock server into JUnit test cases by using the @Rule annotation. This allows JUnit to manage the life cycle, starting the server prior to each test method and stopping it after the method returns.

Similar to the programmatically managed server, a JUnit managed WireMock server can be created as a Java object with the given port number:

If no arguments are supplied, server port will take the default value, 8080. Server host, defaulting to localhost, and other configurations may be specified using the Options interface.

dropConnectionPercentage - network failures

Örnek

Elimizde şöyle bir kod olsun

@RunWith(SpringRunner.class)
@SpringBootTest(webEnvironment = SpringBootTest.WebEnvironment.RANDOM_PORT)
public class NetworkFailureTest {
  @Autowired
  private TestRestTemplate restTemplate;
  @Rule
  public WireMockRule wireMockRule = new WireMockRule(wireMockConfig()
    .dynamicPort()
    .networkLatency(1000, TimeUnit.MILLISECONDS)
    .dropConnectionPercentage(50));
  ...
}

Testleri şöyle yaparız

@Test
public void testGreeting() {
  String response = restTemplate.getForObject("/greeting", String.class);
  assertEquals("Hello, world!", response);
}
@Test
public void testTimeout() {
  wireMockRule.stubFor(get(urlEqualTo("/greeting"))
    .willReturn(aResponse()
      .withStatus(200)
      .withFixedDelay(2000)));

  assertThrows(RestClientException.class, () -> {
    restTemplate.getForObject("/greeting", String.class);
  });
}

shutdownServer metodu

Şöyle yaparız

@Test
public void testConnectionError() {
  wireMockRule.shutdownServer();

  assertThrows(RestClientException.class, () -> {
    restTemplate.getForObject("/greeting", String.class);
  });
}

    .willReturn(aResponse()
        .withFault(Fault.CONNECTION_RESET_BY_PEER)));

Örnek

Şöyle yaparız
