spring – MockRestServiceServer没有正确验证请求

2023年5月14日 221次阅读

我正在尝试为我的
spring-integration流程编写集成测试.我想用

MockRestServiceServer用于记录和匹配传出请求(使用http：outbound-gateway)到Rest服务器.但是,当我调用mockServer的verify方法时,它没有按预期验证.

我正在以下列方式编写测试：

RestTemplate restTemplate = new RestTemplate();
MockRestServiceServer mockServer = MockRestServiceServer.createServer(restTemplate);

mockServer.expect(requestTo("adfasfadf.com")).andExpect(method(HttpMethod.GET));

// Call spring integration flow here

mockServer.verify();

当我检查MockRestServiceServer的验证方法时,它没有调用RequestMatchers的匹配方法,我相信这个逻辑有问题.我在这里错过了什么吗？

/**
 * Verify that all expected requests set up via
 * {@link #expect(RequestMatcher)} were indeed performed.
 * @throws AssertionError when some expectations were not met
 */
public void verify() {
    if (this.expectedRequests.isEmpty() || this.expectedRequests.equals(this.actualRequests)) {
        return;
    }
    throw new AssertionError(getVerifyMessage());
}

最佳答案 经过数小时的调试,我意识到MockRestServiceServer在执行请求期间运行匹配器.因此,如果您有一个围绕请求执行的异常处理程序,那么您的断言永远不会被正确断言.

此代码来自运行匹配器的RequestMatcherClientHttpRequest.

@Override
public ClientHttpResponse executeInternal() throws IOException {
    if (this.requestMatchers.isEmpty()) {
        throw new AssertionError("No request expectations to execute");
    }
    if (this.responseCreator == null) {
        throw new AssertionError("No ResponseCreator was set up. Add it after request expectations, "
                + "e.g. MockRestServiceServer.expect(requestTo(\"/foo\")).andRespond(withSuccess())");
    }
    for (RequestMatcher requestMatcher : this.requestMatchers) {
        requestMatcher.match(this);
    }
    setResponse(this.responseCreator.createResponse(this));

    return super.executeInternal();
}

我认为这应该被视为一个错误,因为我认为断言必须在应用程序执行后执行.
