Question

我正在尝试为预配服务编写Junit。该服务最终会调用VICE客户端并获得证书。当测试中运行Junit时，这浪费了证书，而我想模拟此外部调用。

类结构看起来像这样

class MyService {

    public void provisionTenant() {
        CLient client = generateCertificateClient(Some Params);
        client.enrollCertificate(enrollmentRequest);
    }

    //Private Method 1
    private generateCertificateCleint(Some Params) {
        return new CertClient(createSslContext(), endpoint);
    }

    //Private Method 2
    private createSslContext() {
        //Do something and return context
        return sslContext;
    }

}

// Second Class which is accessed using the new construct in the Service Class
class CertClient {

    private SSLContext;

    CertClient(SSLContext) {
        this.sslContext = ssslContext;
    }

    public enrollCertificate(enrollmentRequest) {
        final URL enrollUrl = asURL(serviceEndpointUrl, RequestType.ENROLL.value());
        executeRequest(enrollURL, enrollmentRequest, POST.value)
    }

    private byte[] executeRequest(final URL url, final Vice2Request request, final String httpMethod) {
        //Do a bunch of steps and return certificate s bytes
        HTTPConnection.writeOutPutStream();
        return getCerttificateAsBVytes(HTTPConnection);
    }

    //Return the Certificate fetched from the Generic POST call
    byte[] getCerttificateAsBytes(HTTPConnection connection) {
        try (InputStream inputStream = connection.getInputStream()) {
            return readBytes(inputStream, responseLength);
        }
    }
}

我有两个挑战，一个是我能够在两个类中的大多数代码上获得83％的覆盖率，但是如果我模拟整个客户端类，那么我将失去代码覆盖率。
有没有一种方法可以模拟第二个类（即客户端类）中的HTTPConnection post调用，客户端不是服务中的Field，但是我可以重构代码并将其设置为Field，但仍然可以通过NEW在方法调用中实例化，有没有办法模拟这个？

我尝试通过为Default CLient .class提供测试准备来尝试PowerMockito.whenNew，但该方法无效，它始终会创建一个新对象。其次，如何模拟服务->（实例化）Cleint->（实例化）HttpConnection。我该如何模拟两个级别的变量？

@Before
public void setUp() throws NoSuchFieldException {
    MockitoAnnotations.initMocks(this);
    ResponseBodyString = "<ResponseBOsy>"
}

 @Test
public void provisionKeyStoreTest() throws Exception {
    PowerMockito.mockStatic(SystemUtil.class);
    PowerMockito.when(SystemUtil.isStoreProvEnabled()).thenReturn(true);
    CertClient certClient = PowerMockito.mock(CertClient.class);
    PowerMockito.whenNew(CertClient.class).withAnyArguments().thenReturn(certClient);
SomeCaller.provisionTenant();
}

如何模拟使用new初始化的类进行的方法调用？
