Wiremock重置方法：如何在Cucumber测试开始时重置Mock

要在Cucumber测试开始时重置WireMock，确保每次场景的Stub调用次数统计不受之前测试的影响，有两种常用实现方式：

方法一：利用Cucumber的@Before Hook直接调用WireMock API #

在Cucumber的钩子类里添加前置方法，每次测试场景启动前重置WireMock的请求记录（或全部状态）。

Java示例代码 #

import io.cucumber.java.Before;
import com.github.tomakehurst.wiremock.WireMockServer;

public class WireMockTestHooks {
    private final WireMockServer wireMockServer;

    // 这里假设WireMockServer实例通过依赖注入或单例方式获取
    public WireMockTestHooks(WireMockServer wireMockServer) {
        this.wireMockServer = wireMockServer;
    }

    @Before
    public void resetWireMockBeforeScenario() {
        // 仅重置请求调用记录，保留已配置的Stub（推荐用于复用Stub的场景）
        wireMockServer.resetRequests();
        
        // 如果需要完全重置Stub配置+请求记录，用下面的方法：
        // wireMockServer.resetAll();
    }
}

方法二：通过WireMock管理HTTP API重置（适合远程WireMock服务） #

如果你的WireMock是独立部署的远程服务，无法直接调用Java API，可以通过发送HTTP请求到WireMock的管理端点完成重置。

Java示例代码 #

import io.cucumber.java.Before;
import java.net.URI;
import java.net.http.HttpClient;
import java.net.http.HttpRequest;
import java.net.http.HttpResponse;

public class WireMockRemoteHooks {
    private static final String WIREMOCK_ADMIN_URL = "http://your-wiremock-host:port/__admin";

    @Before
    public void resetRemoteWireMock() throws Exception {
        HttpClient client = HttpClient.newHttpClient();
        
        // 仅重置请求记录的接口
        HttpRequest resetRequest = HttpRequest.newBuilder()
                .uri(URI.create(WIREMOCK_ADMIN_URL + "/requests/reset"))
                .POST(HttpRequest.BodyPublishers.noBody())
                .build();
        
        client.send(resetRequest, HttpResponse.BodyHandlers.discarding());
        
        // 如果要完全重置Stub+请求记录，调用这个接口：
        // URI.create(WIREMOCK_ADMIN_URL + "/reset")
    }
}

验证调用次数 #

重置完成后，在测试步骤里就可以准确统计当前场景的Stub调用次数了：

import io.cucumber.java.en.Then;
import static com.github.tomakehurst.wiremock.client.WireMock.*;

public class TestStepDefinitions {
    @Then("the stub for path {string} should be called {int} times")
    public void checkStubInvocationCount(String targetPath, int expectedTimes) {
        verify(expectedTimes, getRequestedFor(urlEqualTo(targetPath)));
    }
}
