如何模拟具有lambda表达式的方法

Question

        ClientBuilder builder = ResteasyClientBuilder.newBuilder();
        builder = builder.sslContext(sslContext);
        builder = builder.hostnameVerifier((s1,s2)-> true);

我想模拟builder.hostnameVerifier

我以不同的方式尝试了它，

对于前2行，我可以模拟。我的代码如下：

    PowerMockito.mockStatic(ResteasyClientBuilder.class);
    PowerMockito.when(ResteasyClientBuilder.newBuilder()).thenReturn(clientBuilder);
    PowerMockito.when(clientBuilder.sslContext(sslContext)).thenReturn(clientBuilder);
    PowerMockito.when(this.verifier.verify(Matchers.anyString(), Matchers.anyObject())).thenReturn(true);
    PowerMockito.when(clientBuilder.hostnameVerifier(this.verifier)).thenReturn(clientBuilder);
