我如何使用RestTemplate在集成测试中验证Wiremock故障？

Question

我编写了许多成功的测试来证明HttpStatus代码已正确返回，但是我现在正在寻找验证返回的Fault代码如下。通常我会说

 assertThat(actualResponse.getStatusCode(), is(status));

获取Http状态代码。如何验证故障代码？我目前有以下内容，但不确定如何从ActualResponse正文返回错误代码。

public void shouldReturnSuitableStatusCodeForScenario(String requestFileName,Fault fault, String actualResponseFileName) throws JSONException {
    //Given
    String createRequest = readJsonFromFile(DIRECTORY, requestFileName);

    //When
    ResponseEntity<String> actualResponse = stub.postForEntity(HTTP_LOCALHOST_8081 + "/v1/transaction/", createRequest, String.class);

    //Then
    assertThat(actualResponse, is(fault));
    JSONAssert.assertEquals(readJsonFromFile(DIRECTORY, actualResponseFileName), actualResponse.getBody(), true);
}

当前存根，省略了一些brevit代码：

.willReturn(aResponse() .withHeader(CONTENT_TYPE, APPLICATION_JSON_VALUE) .withFault(Fault.MALFORMED_RESPONSE_CHUNK) .withBodyFile("/malformed_chunk_response.json")));

在您预期有错误的情况下（我假设stub是RestTemplate），可以同时提取状态代码和错误正文的一种方法是这样的：

String statusText;
int statusCode;

stub.setErrorHandler(new ResponseErrorHandler() {
    @Override
    boolean hasError(ClientHttpResponse response) throws IOException {
        return response.statusCode.isError()
    }

    @Override
    void handleError(ClientHttpResponse response) throws IOException {
        statusText = response.getStatusText();
        statusCode = response.rawStatusCode;
    }
});

stub.postForEntity(HTTP_LOCALHOST_8081 + "/v1/transaction/", createRequest, String.class);
