Wiremock：对相同 URL 和内容的多个响应？

Question

也在这里分享：https://github.com/tomakehurst/wiremock/issues/625

我正在编写一个集成测试来验证我与 REST API 交互的应用程序是否正确处理了不成功的请求。为此，我想模拟一个 GET 请求两次发送到 HTTP 端点的场景。第一次请求不成功，响应状态码为500；第二次，请求成功，响应状态码为 200。

考虑以下示例：

@Rule
public WireMockRule wireMockRule 
        = new WireMockRule(wireMockConfig().dynamicPort().dynamicHttpsPort());

@Test
public void testRetryScenario(){

    // First StubMapping
    stubFor(get(urlEqualTo("/my/resource"))
            .withHeader("Accept", equalTo("text/xml"))
            .willReturn(aResponse()
                .withStatus(500) // request unsuccessful with status code 500
                .withHeader("Content-Type", "text/xml")
                .withBody("<response>Some content</response>")));

    // Second StubMapping
    stubFor(get(urlEqualTo("/my/resource"))
            .withHeader("Accept", equalTo("text/xml"))
            .willReturn(aResponse()
                .withStatus(200)  // request successful with status code 200
                .withHeader("Content-Type", "text/xml")
                .withBody("<response>Some content</response>")));

    //Method under test that makes calls to endpoint
    doSomething();

    Thread.sleep(5000);

    //Verify GET request was made again after first attempt
    verify(exactly(2), getRequestedFor(urlEqualTo("/my/resource")));

}

有没有办法避免第二个 StubMapping 覆盖第一个 - 以确保第一次 doSomething() 发出请求时， 具有状态的响应返回代码 500，第二次 返回状态代码为 200 的不同响应？

Answer 1

这就是场景功能的用途。

您需要将两个存根放入场景中（即相同的场景名称），使第一个存根触发到新状态的转换，然后使第二个存根取决于处于第二状态的场景，并且第一个存根取决于场景处于 STARTED 状态。

使用场景功能，这样的事情很有帮助：

// First StubMapping
stubFor(get(urlEqualTo("/my/resource"))
        .withHeader("Accept", equalTo("text/xml"))
        .inScenario("Retry Scenario")
        .whenScenarioStateIs(STARTED)
        .willReturn(aResponse()
            .withStatus(500) // request unsuccessful with status code 500
            .withHeader("Content-Type", "text/xml")
            .withBody("<response>Some content</response>"))
        .willSetStateTo("Cause Success")));

// Second StubMapping
stubFor(get(urlEqualTo("/my/resource"))
        .withHeader("Accept", equalTo("text/xml"))
        .inScenario("Retry Scenario")
        .whenScenarioStateIs("Cause Success")
        .willReturn(aResponse()
            .withStatus(200)  // request successful with status code 200
            .withHeader("Content-Type", "text/xml")
            .withBody("<response>Some content</response>")));
