java - 重载方法的 Groovy 单元测试

Question

使用 MockFor 如何为重载方法编写单元测试。

例如

public HttpResponse execute(HttpUriRequest request, HttpContext context)

和

public HttpResponse execute(HttpHost target, HttpRequest request)

我已经写了：

        def responseMocker = new MockFor(HttpResponse.class)
        HttpResponse response = responseMocker.proxyInstance()
        def requestMocker = new MockFor(HttpUriRequest.class)
        def request = requestMocker.proxyInstance()
        def contextMocker = new MockFor(HttpContext.class)
        def context = contextMocker.proxyInstance();
        def clientMocker = new MockFor(HttpClient.class)
        clientMocker.demand.execute(request, context) { response }

        HttpClientSample client = new HttpClientSample(clientMocker.proxyInstance())

        assertEquals response, client.execute(request,context)

上面的这个测试失败了：

groovy.lang.MissingMethodException：没有方法签名：....

Answer 1

您需要像这样指定所需的方法：

mock.demand.execute { HttpUriRequest request, HttpContext context -> ... }
mock.demand.execute { HttpHost target, HttpRequest request -> ... }

这会将所需的方法绑定到适当的重载方法签名。
