单元测试 - Wiremock 验证失败并出现连接错误

Question

我正在测试一个 spring-boot 应用程序并使用 wiremock 存根来模拟外部 API。在一个测试用例中，我想确保我的存根只被调用一次，但由于连接错误而失败。

我的测试文件：

@SpringBootTest
@AutoConfigureWebTestClient
@ActiveProfiles("test")
class ControllerTest {

    @Autowired
    private lateinit var webClient: WebTestClient

    private lateinit var wireMockServer: WireMockServer

    @BeforeEach
    fun setup() {
        wireMockServer = WireMockServer(8081)
        wireMockServer.start()
        setupStub()
    }

    @AfterEach
    fun teardown() {
        wireMockServer.stop()
    }

    // Stub for external API
    private fun setupStub() {
        wireMockServer.stubFor(
        WireMock.delete(WireMock.urlEqualTo("/externalApiUrl"))
            .willReturn(
                WireMock.aResponse()
                    .withHeader("Content-Type", "application/json")
                    .withStatus(204)
                    .withBodyFile("file.json")
            )
    )
    }

    @Test
    fun test_1() {

        val email = "some-email"
        val Id = 123

        webClient.post()
        .uri { builder ->
            builder.path("/applicationUrl")
                .queryParam("email", email)
                .queryParam("id", Id)
                .build()
        }
        .exchange()
        .expectStatus().isOk

        WireMock.verify(exactly(1), WireMock.deleteRequestedFor(WireMock.urlEqualTo("/externalApiUrl")))
}

当我运行此测试时，我收到以下错误：

org.apache.http.conn.HttpHostConnectException: 连接到 localhost:8080 [localhost/127.0.0.1, localhost/0:0:0:0:0:0:0:1] 失败：连接被拒绝（连接被拒绝)

请让我知道我哪里做错了。提前致谢。

您需要在特定服务器上执行验证调用，例如 wireMockServer.verify() 而不是 WireMock.verify()。
